Aryan invasion theory

Aryan invasion theory or Indo-Aryan migration theory is a hypothesis which came into light in the 19th century. It theorises an outside origin of the of the Sanskrit language. This theory refers to this group as Indo-Aryans, who allegedly brought Sanskrit or its proto form into South Asia around 1500 BCE. The earliest known form of Sanskrit is known as Vedic Sanskrit which belongs to the 12th branch of the Indo European language family as modeled by linguists, namely Indo-Iranian branch. Almost all the modern North Indian (subcontinent) languages including Pakistan and Bangladesh are a part of this Indo-Aryan branch which is a sub-branch of the Indo-Iranian branch. The origin of the Indo European language family or its predecessor the Proto Indo European language is still an unresolved question. There are several hypothesis for its origin including South Russian steppes, Bactria–Margiana Archaeological Complex (short BMAC), Anatolian region and North-west India.

Proponents of Indo-Aryan origin outside of India generally consider migrations into South Asia and Anatolia (ancient Mittani and Kassites) from Central Asia to be around 1500 BCE and 1800 BCE respectively, as a slow diffusion during the Late Harappan period, which led to a language shift in northern India. Further studies by Shrikant Talageri and Koenraad Elst revealed that the Mitannis and Kassites do not belong to the Pre-Rigvedic period but in fact their cultural, linguistic similarity is detected in the late Rigvedic period and is completely absent in the old Rigvedic period. This is concluded based on the study of Rigveda which is composed entirely in India as accepted by all scholars including both proponents and opponents of the Aryan invasion/migration theory.

Scholars such as Koenraad Elst, Michael Danino, Shrikant Talageri and Igor A Tonoyan-Belyayev suggests that the linguistics and textual evidence rather indicates an out of India migration of IE languages. Mitanni and Kassite kingdon archaeologically dated to 16th and 17th century BCE were the Indo-Aryan, particularly Vedic, who belonged to the Late Rigvedic period. Based on this scholars concluded that they must have left the Indian region around 2000BCE. This conclusively falsifies the Aryan invasion/migration theory. If the late Rigvedic period already existed around 2000BCE then the old Rigvedic period must have be dated between 3000-2500 BCE as per Shrikant Talageri and Koenraad Elst. This decisively places the origin of Indo-European languages in north-west India.

Aryan invasion or migration suffers from grave flaws such as the complete absence of evidence in archaeology, cultural change, linguistics and textual. Majority scholars seems to have a consensus that there is almost no cultural change detected in India from mature Harappan period to late or post Harappan period. The modern South Asian population, on average has 12.6% of steppe ancestry with a few communities showing as high as 29.8% in Kalash and 28.1% in Pathan community in western Pakistan. Some scholar claim that this is a proof of Aryan migration into South Asia. But Indian geneticist such as Niraj Rai and Gyaneshwar Chaubey suggest that this population mix is a very recent phenomena and definitely did not occur in second millennium BCE.

Scholars have also pointed out that if Sanskrit had come from outside into India then the river names or the place names in north India should have non-Sanskrit names which is not the case as also admitted by the prominent Aryan invasionist Michael Witzel. Since the Indo-Aryans are supposed to have started composing Rigveda as soon as they arrived in India, even in that earliest Rigvedic period, it shows no traces of rivers or places having non-Sanskrit names. This is the scenario which is not seen anywhere else in the Indo European world. In contrast, many rivers of Europe have non-Indo European names, their origin is found in languages spoken prior to the arrival of Indo European languages. This is not the case in India, which as per some scholars is an evidence that Aryans and Sanskrit were native to North India and did not come from outside. As per Shrikant Talageri, there is not a single river or place name found in Rigveda which is of non Indo European origin.

Terminology

The Aryan invasion theory (AIT) is more recently also known as the Aryan migration theory (AMT) or Indo-Aryan migration theory. Earlier models were built on the belief of an invasion of Aryans, but since the discovery of the Indus Valley Civilization and due to the lack of evidence for any invasion, Witzel and others now prefer the term 'migration'. Indologist Koenraad Elst writes:

The theory of which we are about to discuss the linguistic evidence, is widely known as the ‘Aryan invasion theory’ (AIT). I will retain this term even though some scholars object to it, preferring the term ‘immigration’ to ‘invasion’. They argue that the latter term represents a long-abandoned theory of Aryan warrior bands attacking and subjugating the peaceful Indus civilization..... What makes an immigration into an invasion is not the means used but the end achieved: after an invasion, the former outsiders are not merely in, as in an immigration, but they are also in charge. If the newcomers end up imposing their (cultural, religious, linguistic) identity rather than adopting the native identity, the result is the same as it would have been in the case of a military conquest, viz. that outsiders have made the country their own, and that natives who remain true to their identity (such as Native Americans in the US) become strangers or second-class citizens in their own country.” ....It is entirely reasonable to call this development an ‘invasion’ and to speak of the prevalent paradigm as the ‘Aryan invasion theory’.”

Fundaments of the Indo-Aryan Migration theory

The Indo-Aryan Migration theory is part of a larger theoretical framework. This framework intends to explain the migration of Indo European language from a common homeland.A common homeland is a place where all 12 or more branches of the Indo European languages lived together. The study of these languages and their hypothesised migration models generally combines linguistic, archaeological, culture and anthropological research.[1][2] This provides an overview of the development of indo-European languages, and the spread of these Indo-European languages by migration and acculturation.[2] In recent time, genetics have also come into the picture where migration patterns have been linked with the migration of languages.

Linguistics: relationships between languages

The linguistic part traces the connections between the various Indo-European languages, and reconstructs proto-Indo-European. This is possible because the processes that change languages are not random, but follow strict patterns. Especially sound shifts, the changing of vowels and consonants, are important, although grammar (especially morphology) and the lexicon (vocabulary) may also be significant. Historical-comparative linguistics thus makes it possible to see great similarities between languages which at first sight might seem very different.[2] This idea of common homeland of all the IE languages is widely accepted among the scholars. Significant amount of efforts have been made to locate this homeland but scholarly consensus do not seem to point to a single location.

Archaeology

The archaeology seems to provide evidence of cultural changes which then can be corroborated with other fields to science to help determine the movement of people and perhaps languages. During the invasion of Central and western Europe by the people of Yamnaya culture along with spread of IE languages made the Bell Beaker pottery widespread between 2750 BC and 2500 BC.[3] This way migrations bring in a change in culture which is clearly reflected in the archaeological record. But no such change is seen in the Indus region that could even hint of any such migration in the second millenium BCE. It is evidence from the Rakhigarhi DNA publication that even genetically no such migration occurred into the Indian subcontinent prior to second millennium BC either. Eastward emerged the Sintashta culture (2100–1800 BCE), from which developed the Andronovo culture (1800–1400 BCE). This culture interacted with the Bactria-Margiana Culture (2300–1700 BCE)

Genetics

While genetics have been able to solve the puzzle of languages from South Russian steppes referred to as Yamnaya culture post 3000 BCE into Europe. Where we find large population replacements. Britain showing 100% Y chromosome replacement with 90% whole genome replacement and Ibera (present day spain and Portugal) showing similar 100% Y-chromosome replacement and 40% whole genome replacement. This large scale invasion of Europe leading to population replacement presents a conclusive evidence of language replacement in Europe around 2500 BCE. This invasion came with a new culture referred to as the Bell Beaker culture. While this has been the case in Europe but no such thing is found in the Indian subcontinent or South Asia. Due to the tropical weather in India and geochemistry of the soil, many DNA samples found had been in contaminated state, which resulted in DNA samples being useless. For the first time in Rakhigarhi (Harappan site) a relatively working DNA sample was sequenced and the findings were published in Sept 2019 in Cell Journal. This paper made some surprising conclusions as outlined below.

• The Indus Valley is the single largest source of ancestry of modern South Asians.
• Indus Valley people and the ancient Iranians had a common ancestor who lived more than 12,000 years ago.
• The farming in India is indigenous.

Narasimhan et al 2019, further concluded that the Indus Valley genome is the single largest ancestry of present day South Asians with 87.4% of ancestry coming directly from the Indus Valley. In genetics it is accepted that north and south Indians share a common maternal ancestry. While the Narasimhan et al 2019, after studying the DNA samples samples found at SWAT Valley (North-west Pakistan) dating to around 1000BC finds that these samples represent a mixture of Indus Valley people and some population with steppe ancestry. This genomic admixture has been dated to have occurred between 1900BC and 1400BC. Although the route of that ancestry is not known as asserted by Narasimhan et al. Based on this, the paper seemed to have concluded that the steppe ancestry among modern South Asians came with a steppe migration to South Asia between 2000-1500 BCE. Although after the analysis of their published supplementary data, it is found that the steppe population who mixed with SWAT Valley population is different from the population whose ancestry is found in the modern day South Asians. The absence of steppe R1a gene in the SWAT Valley aDNA raises more questions to the origin of that steppe population which seemed to have mixed with Indus people living on the periphery of South Asia in SWAT Valley. On average modern South Asian have 12.6% steppe ancestry component, which in contrast is too small in comparison to what has been seen in Europe with incoming of Bell Beaker culture. Regardless, Narsimhan et al 2019, seems to have inferred that this is when the Sanskrit arrived in India with Steppe migrations despite all other disciplines of science providing evidence against any such language shift in the vast landscape of the northern South Asia. The Rigveda which as per the Aryan Invasionists is the text which the Aryans started to write as soon as they arrived in South Asia, shows not a faintest trace of the presence of any other language in the region. This is being criticised by Indian scholars to be an example of working with a preconceived notion that Indo European languages originated elsewhere in Central Asia contrary to what the evidence suggests. Some Indian geneticists such as Niraj Rai (who also co-authored Narasimhan et al 2019) and Gyandesndra Chaubey suggests that based on their ongoing unpublished studies on the Indian Genome project, the steppe ancestry seems to have entered the South Asia much later, post 1000BCE.

Development of the Aryan Migration theory

Similarities between Sanskrit, Greek, Latin, Persian, Celtic and German

When the British started to colonize India in the 18th century, they had to impose a legal system on both the British merchants and the Indians. The Indians already had a legal system, which was unknown to the British colonizers. To integrate these systems, the British had to learn Sanskrit, a task which was given to Sir William Jones. He learned Sanskrit, and studied Sanskrit texts, at the ancient Hindu university at Nadiya. He noted the similarities of Sanskrit with Persian, English, Latin, Greek and Gothic. After three years of studies, in an announcement to the Asiatic Society of Bengal, he made the famous statement:

The Sanskrit language, whatever be its antiquity, is of a wonderful structure; more perfect than the Greek, more copious than the Latin, and more exquisitely refined than either, yet bearing to both of them a stronger affinity, both in the roots of verbs and in the forms of grammar, than could possibly have been produced by accident; so strong indeed, that no philologer could examine them all three, without believing them to have sprung from some common source, which, perhaps, no longer exists: there is a similar reason, though not quite so forcible, for supposing that both the Gothic and the Celtic, though blended with a very different idiom, had the same origin with the Sanskrit; and the old Persian might be added to the same family, if this were the place for discussing any question concerning the antiquities of Persia.

Jones concluded that all these languages originated from the same source.

Homeland

Most scholars assumed a homeland either in Europe or in Western Asia, and Sanskrit must in this case have reached India by a language transfer from west to east.

Some scholars favoured an Indian "homeland". In 19th century Indo-European studies, the language of the Rigveda was the most archaic Indo-European language known to scholars, indeed the only records of Indo-European that could reasonably claim to date to the Bronze Age. This primacy of Sanskrit inspired some scholars, such as Friedrich Schlegel, to assume that the locus of the Proto-Indo-European Urheimat (primary homeland) had been in India, with the other dialects spread to the west by historical migration. This was however never a mainstream position even in the 19th century.

With the 20th-century discovery of Bronze-Age attestations of Indo-European (Anatolian, Mycenaean Greek), Vedic Sanskrit lost its special status as the most archaic Indo-European language known.

Aryan race

File:Aryans entering India.jpg

A 1910 depiction of Aryan's entering India from Hutchinson's History of the Nations

In the 1850s Max Müller introduced the notion of two Aryan races, a western and an eastern one, who migrated from the Caucasus into Europe and India respectively. Müller dichotomized the two groups, ascribing greater prominence and value to the western branch. Nevertheless, this "eastern branch of the Aryan race was more powerful than the indigenous eastern natives, who were easy to conquer." By the 1880s, his ideas had been "hijacked" by racist ethnologists. For example, as an exponent of race science, colonial administrator Herbert Hope Risley (1851 – 1911) used the ratio of the width of a nose to its height to divide Indian people into Aryan and Dravidian races, as well as seven castes.

Müller's work contributed to the developing interest in Aryan culture, which often set Indo-European ('Aryan') traditions in opposition to Semitic religions. He was "deeply saddened by the fact that these classifications later came to be expressed in racist terms," as this was far from his intention. For Müller the discovery of common Indian and European ancestry was a powerful argument against racism, arguing that "an ethnologist who speaks of Aryan race, Aryan blood, Aryan eyes and hair, is as great a sinner as a linguist who speaks of a dolichocephalic dictionary or a brachycephalic grammar" and that "the blackest Hindus represent an earlier stage of Aryan speech and thought than the fairest Scandinavians". In his later work, Max Müller took great care to limit the use of the term "Aryan" to a strictly linguistic one.

"Aryan invasion"

The excavation of the Harappa, Mohenjo-daro and Lothal sites of the Indus Valley Civilization (IVC) in the 1920, showed that northern India already had an advanced culture when the Indo-Aryans migrated into the area. The theory changed from a migration of advanced Aryans towards a primitive aboriginal population, to a migration of nomadic people into an advanced urban civilization, comparable to the Germanic migrations during the Fall of the Western Roman Empire, or the Kassite invasion of Babylonia.

This possibility was for a short time seen as a hostile invasion into northern India. The decline of the Indus Valley Civilisation at precisely the period in history in which the Indo-Aryan migrations probably took place, seemed to provide independent support of such an invasion. This argument was proposed by the mid-20th century archaeologist Mortimer Wheeler, who interpreted the presence of many unburied corpses found in the top levels of Mohenjo-daro as the victims of conquest wars, and who famously stated that the god "Indra stands accused" of the destruction of the Civilisation.

This position was soon left by the scholarly community, noticing that no evidence was found, and that the skeletons were found to be hasty interments, not massacred victims. Wheeler himself also nuanced this interpretation in later publications, stating "This is a possibility, but it can't be proven, and it may not be correct." Wheeler further notes that the unburied corpses may indicate an event in the final phase of human occupation of Mohenjo-Daro, and that there-after the place was uninhabited, but that the decay of Mohenjo-Daro has to be ascribed to structural causes such as salinisation.

Nevertheless, although "no informed Western scholar speaks of 'invasions' anymore," critics of the Indo-Aryan Migration theory continue to present the theory as an "Aryan Invasion Theory", presenting it as a racist and colonialist discourse:

The theory of an immigration of IA speaking Arya ("Aryan invasion") is simply seen as a means of British policy to justify their own intrusion into India and their subsequent colonial rule: in both cases, a "white race" was seen as subduing the local darker colored population.

Aryan migration

In the later 20th century, ideas were refined along with data accrual, and migration and acculturation were seen as the methods whereby Indo-Aryans and their language and culture spread into northwest India around 1500 BC. The term "invasion" is only being used nowadays by opponents of the Indo-Aryan Migration theory. Michael Witzel:

...it has been supplanted by much more sophisticated models over the past few decades [...] philologists first, and archaeologists somewhat later, noticed certain inconsistencies in the older theory and tried to find new explanations, a new version of the immigration theories.

These changes were thought to be in line with changes in thinking about language transfer in general, such as the migration of the Greeks into Greece (between 2100 and 1600 BC) and their adoption of a syllabic script, Linear B, from the pre-existing Linear A, with the purpose of writing Mycenaean Greek, or the Indo-Europeanization of Western Europe (in stages between 2200 and 1300 BC).

Future directions

Mallory notes that with the development and the growing sophistication of the knowledge on the Indo-European migrations and their purported homeland, new questions arise, and that "it is evident that we still have a very long way to go." One of those questions is the origin of the shared agricultural vocabulary, and the earliest dates for agriculturalism in areas settled by the Indo-Europeans. Those dates seem to be too late too account for the shared vocabulary, and raise the question what their origin is. In 2016, publications are expected on DNA-analysis of Harappans, which may answer the question to which non-Indian populations they were related.

Linguistics: relationships between languages

Linguistic research traces the connections between the various Indo-European languages, and reconstructs proto-Indo-European. Accumulated linguistic evidence points to the Indo-Aryan languages as intrusive into South Asia, some time in the 2nd millennium BC. The language of the Rigveda, the earliest stratum of Vedic Sanskrit, is assigned to about 1500–1200 BC.

Comparative method

Connections between languages can be traced because the processes that change languages are not random, but follow strict patterns. Especially sound shifts, the changing of vowels and consonants, are important, although grammar (especially morphology) and the lexicon (vocabulary) may also be significant. Historical-comparative linguistics thus makes it possible to see great similarities between languages which at first sight might seem very different.

Linguistics use the comparative method to study the development of languages by performing a feature-by-feature comparison of two or more languages with common descent from a shared ancestor, as opposed to the method of internal reconstruction, which analyses the internal development of a single language over time. Ordinarily both methods are used together to reconstruct prehistoric phases of languages, to fill in gaps in the historical record of a language, to discover the development of phonological, morphological, and other linguistic systems, and to confirm or refute hypothesized relationships between languages.

The comparative method aims to prove that two or more historically attested languages are descended from a single proto-language by comparing lists of cognate terms. From them, regular sound correspondences between the languages are established, and a sequence of regular sound changes can then be postulated, which allows the proto-language to be reconstructed. Relation is deemed certain only if at least a partial reconstruction of the common ancestor is feasible, and if regular sound correspondences can be established with chance similarities ruled out.

The comparative method was developed over the 19th century. Key contributions were made by the Danish scholars Rasmus Rask and Karl Verner and the German scholar Jacob Grimm. The first linguist to offer reconstructed forms from a proto-language was August Schleicher, in his Compendium der vergleichenden Grammatik der indogermanischen Sprachen, originally published in 1861.

Proto-Indo-European

Proto-Indo-European (PIE) is the linguistic reconstruction of the common ancestor of the Indo-European languages. PIE was the first proposed proto-language to be widely accepted by linguists. Far more work has gone into reconstructing it than any other proto-language, and it is by far the best understood of all proto-languages of its age. During the 19th century, the vast majority of linguistic work was devoted to reconstruction of Proto-Indo-European or its daughter proto-languages such as Proto-Germanic, and most of the current techniques of linguistic reconstruction in historical linguistics (e.g., the comparative method and the method of internal reconstruction) were developed as a result. These methods supply all of our knowledge concerning PIE, since there is no written record of the language.

Scholars estimate that PIE may have been spoken as a single language (before divergence began) around 3500 BC, though estimates by different authorities can vary by more than a millennium. A number of hypotheses have been proposed for the origin and spread of the language, the most popular among linguists being the Kurgan hypothesis, which postulates an origin in the Pontic–Caspian steppe of Eastern Europe. Features of the culture of the speakers of PIE, known as Proto-Indo-Europeans, have also been reconstructed based on the shared vocabulary of the early attested Indo-European languages.

The existence of PIE was first postulated in the 18th century by Sir William Jones, who observed the similarities between Sanskrit, Ancient Greek, and Latin. By the early 20th century, well-defined descriptions of PIE had been developed that are still accepted today (with some refinements). The largest developments of the 20th century were the discovery of the Anatolian and Tocharian languages and the acceptance of the laryngeal theory. The Anatolian languages have also spurred a major re-evaluation of theories concerning the development of various shared Indo-European language features and the extent to which these features were present in PIE itself. Relationships to other language families, including the Uralic languages, have been proposed but remain controversial.

PIE is thought to have had a complex system of morphology that included inflectional suffixes as well as ablaut (vowel alterations, as preserved in English sing, sang, sung). Nouns and verbs had complex systems of declension and conjugation respectively.

Arguments against an Indian origin of proto-Indo-European

Diversity

According to the linguistic center of gravity principle, the most likely point of origin of a language family is in the area of its greatest diversity. By this criterion, Northern India, home to only a single branch of the Indo-European language family (i. e., Indo-Aryan), is an exceedingly unlikely candidate for the Indo-European homeland, compared to Central-Eastern Europe, for example, which is home to the Italic, Venetic, Illyrian, Albanian, Germanic, Baltic, Slavic, Thracian and Greek branches of Indo-European.

Both mainstream Urheimat solutions locate the Proto-Indo-European homeland in the vicinity of the Black Sea.

Dialectical variation

File:Indo-European isoglosses.png

Indo-European isoglosses, including the centum and satem languages (blue and red, respectively), augment, PIE *-tt- > -ss-, *-tt- > -st-, and m-endings.

It has been recognized since the mid-19th century, beginning with Schmidt and Schuchardt, that a binary tree model cannot capture all linguistic alignments; certain areal features cut across language groups and are better explained through a model treating linguistic change like waves rippling out through a pond. This is true of the Indo-European languages as well. Various features originated and spread while Proto-Indo-European was still a dialect continuum. These features sometimes cut across sub-families: for instance, the instrumental, dative and ablative plurals in Germanic and Balto-Slavic feature endings beginning with -m-, rather than the usual -*bh-, e.g. Old Church Slavonic instrumental plural synъ-mi 'with sons', despite the fact that the Germanic languages are centum, while Balto-Slavic languages are satem.

The strong correspondence between the dialectical relationships of the Indo-European languages and their actual geographical arrangement in their earliest attested forms makes an Indian origin, as suggested by the Out of India Theory, unlikely.

Substrate influence

Dravidian and other South Asian languages share with Indo-Aryan a number of syntactical and morphological features that are alien to other Indo-European languages, including even its closest relative, Old Iranian. Phonologically, there is the introduction of retroflexes, which alternate with dentals in Indo-Aryan; morphologically there are the gerunds; and syntactically there is the use of a quotative marker (iti). These are taken as evidence of substratum influence.

It has been argued that Dravidian influenced Indic through "shift", whereby native Dravidian speakers learned and adopted Indic languages. The presence of Dravidian structural features in Old Indo-Aryan is thus plausibly explained, that the majority of early Old Indo-Aryan speakers had a Dravidian mother tongue which they gradually abandoned. Even though the innovative traits in Indic could be explained by multiple internal explanations, early Dravidian influence is the only explanation that can account for all of the innovations at once – it becomes a question of explanatory parsimony; moreover, early Dravidian influence accounts for several of the innovative traits in Indic better than any internal explanation that has been proposed.

A pre-Indo-European linguistic substratum in South Asia would be a good reason to exclude India as a potential Indo-European homeland. However, several linguists, all of whom accept the external origin of the Aryan languages on other grounds, are still open to considering the evidence as internal developments rather than the result of substrate influences, or as adstratum effects.

The Sintashta, Andronovo, Bactria-Margiana and Yaz cultures have been associated with Indo-Iranian migrations in Central Asia. The Gandhara Grave, Cemetery H, Copper Hoard and Painted Grey Ware cultures are candidates for subsequent cultures within south India associated with Indo-Aryan movements. The decline of the Indus Valley Civilisation predates the Indo-Aryan migrations, but archeological data show a cultural continuity in the archeological record. Together with the presence of Dravidian loanwords in the Rig veda, this argues in favor of an interaction between post-Harappan and Indo-Aryan cultures.

Stages of migrations

About 6,000 years ago the Indo-Europeans started to spread out from their proto-Indo-European homeland in Central Eurasia, between the southern Ural Mountains, the North Caucasus, and the Black Sea. About 4,000 years ago Indo-European speaking peoples started to migrate out of the Eurasian steppes.

Diffusion from the "Urheimat"

File:Yamna-en.svg

Yamna culture

Most scholars regard the middle Volga, which was the location of the Samara culture (late 6th and early 5th millennium BCE), and the Yamna culture, to be the "Urheimat" of the Indo-Europeans, as described by the Kurgan hypothesis. From this "Urheimat", Indo-European languages spread throughout the Eurasian steppes between ca. 4,500 and 2,500 BCE, forming the Yamna culture.

Anthony - Multiple migrations

David Anthony gives an elaborate overview of the sequence of migrations.

The oldest attested Indo-European language is Hittite, which belongs to the oldest written Indo-European languages, the Anatolian branch. Although the Hittites are placed in the 2nd millennium BCE, the Anatolian branch seems to predate Proto-Indo-European, and may have developed form an older Pre-Proto-Indo-European ancestor. If it separated from Proto-Indo-European, it is likely to have done so between 4500-3500 BCE.

A migration of archaic Proto-Indo-European speaking steppe herders took place into the lower Danube valley about 4200-4000 BCE, either causing or taking advantage of the collapse of Old Europe.

According to Mallory and Adams, migrations southward founded the Maykop culture (c. 3500–2500 BCE), and eastward the Afanasevo culture (c. 3500–2500 BCE), which developed into the Tocharians (c. 3700–3300 BCE).

According to Anthony, between 3100-2800/2600 BCE, a real folk migration of Proto-Indo-European speakers from the Yamna-culture took place toward the west, into the Danube Valley. These migrations probably split off Pre-Italic, Pre-Celtic and Pre-Germanic from Proto-Indo-European. According to Anthony, this was followed by a movement north, which split away Baltic-Slavic c. 2800 BCE. Pre-Armenian split off at the same time. According to Parpola, this migration is related to the appearance of Indo-European speakers from Europe in Anatolia, and the appearance of Hittite.

The Corded Ware culture in Middle Europe (ca. 2900–2450/2350 cal. BC), has been associated with some of the Indo-European family of languages. According to Haak et al. (2015) a massive migration took place from the Eurasian steppes to Central Europe. This migration is closely associated with the Corded Ware culture.

The Indo-Iranian language and culture emerged in the Sintashta culture (c. 2100–1800 BCE), where the chariot was invented. Allentoft et al. (2015) found close autosomal genetic relationship between peoples of Corded Ware culture and Sintashta culture, which "suggests similar genetic sources of the two," and may imply that "the Sintashta derives directly from an eastward migration of Corded Ware peoples."

The Indo-Iranian language and culture was further developed in the Andronovo culture (c. 1800–1400 BCE), and influenced by the Bactria–Margiana Archaeological Complex (c. 2300–1700 BCE). The Indo-Aryans split off around 1800–1600 BCE from the Iranians, whereafter Indo-Aryan groups moved to the Levant (Mitanni), northern India (Vedic people, c. 1500 BCE), and China (Wusun). Thereafter the Iranians migrated into Iran.

Central Asia: formation of Indo-Iranians

Indo-Iranian peoples are a grouping of ethnic groups consisting of the Indo-Aryan, Iranian, Dardic and Nuristani peoples; that is, speakers of Indo-Iranian languages, a major branch of the Indo-European language family.

The Proto-Indo-Iranians are commonly identified with the Andronovo culture, that flourished ca. 1800–1400 BCE in an area of the Eurasian steppe that borders the Ural River on the west, the Tian Shan on the east. The older Sintashta culture (2100–1800), formerly included within the Andronovo culture, is now considered separately, but regarded as its predecessor, and accepted as part of the wider Andronovo horizon.

The Indo-Aryan migration was part of the Indo-Iranian migrations from the Andronovo culture into Anatolia, Iran and South-Asia.

Sintashta-Petrovka culture

The Sintashta culture, also known as the Sintashta-Petrovka culture or Sintashta-Arkaim culture, is a Bronze Age archaeological culture of the northern Eurasian steppe on the borders of Eastern Europe and Central Asia, dated to the period 2100–1800 BCE. The Sintashta culture is probably the archaeological manifestation of the Indo-Iranian language group.

The Sintashta culture emerged from the interaction of two antecedent cultures. Its immediate predecessor in the Ural-Tobol steppe was the Poltavka culture, an offshoot of the cattle-herding Yamnaya horizon that moved east into the region between 2800 and 2600 BCE. Several Sintashta towns were built over older Poltovka settlements or close to Poltovka cemeteries, and Poltovka motifs are common on Sintashta pottery. Sintashta material culture also shows the influence of the late Abashevo culture, a collection of Corded Ware settlements in the forest steppe zone north of the Sintashta region that were also predominantly pastoralist. Allentoft et al. (2015) also found close autosomal genetic relationship between peoples of Corded Ware culture and Sintashta culture.

The earliest known chariots have been found in Sintashta burials, and the culture is considered a strong candidate for the origin of the technology, which spread throughout the Old World and played an important role in ancient warfare. Sintashta settlements are also remarkable for the intensity of copper mining and bronze metallurgy carried out there, which is unusual for a steppe culture.

Because of the difficulty of identifying the remains of Sintashta sites beneath those of later settlements, the culture was only recently distinguished from the Andronovo culture. It is now recognised as a separate entity forming part of the 'Andronovo horizon'.

Andronovo culture

File:Indo-Iranian origins.png

Archaeological cultures associated with Indo-Iranian migrations and Indo-Aryan migrations (after EIEC). The Andronovo, BMAC and Yaz cultures have often been associated with Indo-Iranian migrations. The GGC, Cemetery H, Copper Hoard and PGW cultures are candidates for cultures associated with Indo-Aryan migrations.

The Andronovo culture is a collection of similar local Bronze Age Indo-Iranian cultures that flourished ca. 1800–1400 BCE in western Siberia and the west Asiatic steppe. It is probably better termed an archaeological complex or archaeological horizon. The name derives from the village of Andronovo (), where in 1914, several graves were discovered, with skeletons in crouched positions, buried with richly decorated pottery. The older Sintashta culture (2100–1800), formerly included within the Andronovo culture, is now considered separately, but regarded as its predecessor, and accepted as part of the wider Andronovo horizon.

Sub-cultures have been distinguished:

• Alakul (1800–1400 BCE)
• Fedorovo (1700–1300 BCE)
• Alekseyevka (1200–1000 BCE)

The geographical extent of the culture is vast and difficult to delineate exactly. On its western fringes, it overlaps with the approximately contemporaneous, but distinct, Srubna culture in the Volga-Ural interfluvial. To the east, it reaches into the Minusinsk depression, with some sites as far west as the southern Ural Mountains, overlapping with the area of the earlier Afanasevo culture. Additional sites are scattered as far south as the Koppet Dag (Turkmenistan), the Pamir (Tajikistan) and the Tian Shan (Kyrgyzstan). The northern boundary vaguely corresponds to the beginning of the Taiga. In the Volga basin, interaction with the Srubna culture was the most intense and prolonged, and Federovo style pottery is found as far west as Volgograd.

Towards the middle of the 2nd millennium, the Andronovo cultures begin to move intensively eastwards. They mined deposits of copper ore in the Altai Mountains and lived in villages of as many as ten sunken log cabin houses measuring up to 30m by 60m in size. Burials were made in stone cists or stone enclosures with buried timber chambers.

In other respects, the economy was pastoral, based on cattle, horses, sheep, and goats. While agricultural use has been posited, no clear evidence has been presented.

Most researchers associate the Andronovo horizon with early Indo-Iranian languages, though it may have overlapped the early Uralic-speaking area at its northern fringe, including the Turkic-speaking area at its northeastern fringe.

Based on its use by Indo-Aryans in Mitanni and Vedic India, its prior absence in the Near East and Harappan India, and its 19-20th century BC attestation at the Andronovo site of Sintashta, Kuzmina (1994) argues that the chariot corroborates the identification of Andronovo as Indo-Iranian. Klejn (1974) and Brentjes (1981) find the Andronovo culture much too late for an Indo-Iranian identification since chariot-wielding Aryans appear in Mitanni by the 15th to 16th century BC. However, Anthony & Vinogradov (1995) dated a chariot burial at Krivoye Lake to about 2000 BC and a Bactria-Margiana burial that also contains a foal has recently been found, indicating further links with the steppes.

Mallory (as cited in Bryant 2001:216) notes the difficulties of making a case for expansions from Andronovo to northern India, and that attempts to link the Indo-Aryans to such sites as the Beshkent and Vakhsh cultures "only gets the Indo-Iranian to Central Asia, but not as far as the seats of the Medes, Persians or Indo-Aryans". However he has also developed the "kulturkugel" model that has the Indo-Iranians taking over Bactria-Margiana cultural traits but preserving their language and religion while moving into Iran and India.

Bactria-Margiana Culture

File:BMAC.png

The extent of the Bactria-Margiana Culture (after EIEC).

The Bactria-Margiana Culture, also called "Bactria-Margiana Archaeological Complex", was a non-Indo-European culture which influenced the Indo-Iranians. It was centered in what is nowadays northwestern Afghanistan and southern Turkmenistan. Proto-Indo-Iranian arose due to this influence.

The Indo-Iranians also borrowed their distinctive religious beliefs and practices from this culture. According to Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the contact zone between the Zeravshan River (present-day Uzbekistan) and (present-day) Iran. It was "a syncretic mixture of old Central Asian and new Indo-European elements", which borrowed "distinctive religious beliefs and practices" from the Bactria–Margiana Culture. At least 383 non-Indo-European words were borrowed from this culture, including the god Indra and the ritual drink Soma.

The characteristically Bactria-Margiana (southern Turkmenistan/northern Afghanistan) artifacts found at burials in Mehrgarh and Baluchistan are explained by a movement of peoples from Central Asia to the south. The Indo-Aryan tribes may have been present in the area of the BMAC from 1700 BC at the latest (incidentally corresponding with the decline of that culture).

From the BMAC, the Indo-Aryans moved into south Asia. According to Bryant, the Bactria-Margiana material inventory of the Mehrgarh and Baluchistan burials is "evidence of an archaeological intrusion into the subcontinent from Central Asia during the commonly accepted time frame for the arrival of the Indo-Aryans".

Two waves of Indo-Iranian migration

The Indo-Iranian migrations took place in two waves, belonging to the second and the third stage of Beckwith's description of the Indo-European migrations. The first wave consisted of the Indo-Aryan migration into the Levant, founding the Mitanni kingdom in northern Syria (ca.1500-1300 BCE), and the migration south-eastward of the Vedic people, over the Hindu Kush into northern India. Christopher I. Beckwith suggests that the Wusun, an Indo-European Europoid people of Inner Asia in antiquity, were also of Indo-Aryan origin. The second wave is interpreted as the Iranian wave.

First wave - Indo-Aryan migrations

Mittani

File:Near East 1400 BCE.png

Map of the Near East ca. 1400 BC showing the Kingdom of Mitanni at its greatest extent

Mitanni (Hittite cuneiform KUR^URUMi-ta-an-ni), also Mittani (Mi-it-ta-ni) or Hanigalbat (Assyrian Hanigalbat, Khanigalbat cuneiform Ḫa-ni-gal-bat) or Naharin in ancient Egyptian texts was a Hurrian-speaking state in northern Syria and south-east Anatolia from ca. 1500 BC–1300 BC.

Founded by an Indo-Aryan ruling class governing a predominately Hurrian population, Mitanni came to be a regional power after the Hittite destruction of Amorite Babylon and a series of ineffectual Assyrian kings created a power vacuum in Mesopotamia. At the beginning of its history, Mitanni's major rival was Egypt under the Thutmosids. However, with the ascent of the Hittite empire, Mitanni and Egypt made an alliance to protect their mutual interests from the threat of Hittite domination.

At the height of its power, during the 14th century BC, Mitanni had outposts centered on its capital, Washukanni, whose location has been determined by archaeologists to be on the headwaters of the Khabur River. Their sphere of influence is shown in Hurrian place names, personal names and the spread through Syria and the Levant of a distinct pottery type. Eventually, Mitanni succumbed to Hittite and later Assyrian attacks, and was reduced to the status of a province of the Middle Assyrian Empire.

The earliest written evidence for an Indo-Aryan language is found not in Northwestern India and Pakistan, but in northern Syria, the location of the Mitanni kingdom. The Mitanni kings took Old Indic throne names, and Old Indic technical terms were used for horse-riding and chariot-driving. The Old Indic term r'ta, meaning "cosmic order and truth", the central concept of the Rigveda, was also employed in the Mitanni kingdom. Old Indic gods, including Indra, were also known in the Mitanni kingdom.

Migration into northern India

File:Rigvedic geography.jpg

Geography of the Rigveda, with river names; the extent of the Swat and Cemetery H cultures are indicated.

The standard model for the entry of the Indo-European languages into India is that Indo-Aryan migrants went over the Hindu Kush, forming the Gandhara grave culture or Swat culture, in present-day Swat valley, either into the headwaters of the Indus or the Ganges (probably both). The Gandhara grave culture, which emerged c. 1600 BC, and flourished from c. 1500 BCE to 500 BCE in Gandhara, modern-day Pakistan and Afghanistan, is thus the most likely locus of the earliest bearers of Rigvedic culture.

Based on this Parpola postulates a first wave of immigration from as early as 1900 BC, corresponding to the Cemetery H culture, and an immigration to the Punjab ca. 1700-1400 BCE.

According to Kochhar there were three waves of Indo-Aryan immigration that occurred after the mature Harappan phase:

1. the "Murghamu" (Bactria-Margiana Culture) related people who entered Baluchistan at Pirak, Mehrgarh south cemetery, and other places, and later merged with the post-urban Harappans during the late Harappans Jhukar phase (2000-1800 BCE);
2. the Swat IV that co-founded the Harappan Cemetery H phase in Punjab (2000-1800 BCE);
3. and the Rigvedic Indo-Aryans of Swat V that later absorbed the Cemetery H people and gave rise to the Painted Grey Ware culture (PGW) (to 1400 BCE).

Gandhara grave culture

About 1800 BC, there is a major cultural change in the Swat Valley with the emergence of the Gandhara grave culture. With its introduction of new ceramics, new burial rites, and the horse, the Gandhara grave culture is a major candidate for early Indo-Aryan presence. The two new burial rites—flexed inhumation in a pit and cremation burial in an urn—were, according to early Vedic literature, both practiced in early Indo-Aryan society. Horse-trappings indicate the importance of the horse to the economy of the Gandharan grave culture. Two horse burials indicate the importance of the horse in other respects. Horse burial is a custom that Gandharan grave culture has in common with Andronovo, though not within the distinctive timber-frame graves of the steppe.

Spread of Vedic-Brahmanic culture

During the Early Vedic Period (ca.1500-800 BCE) the Vedic culture was centered in the northern Punjab, or Sapta Sindhu. During the Later Vedic Period (ca.800-500 BCE) the Vedic culture started to extend into the western Ganges Plain, centering on Kuru and Panchala, and had some influence at the central Ganges Plain after 500 BCE. Sixteen Mahajanapada developed at the Ganges Plain, of which the Kuru and Panchala became the most notable developed centers of Vedic culture, at the western Ganges Plain

The Central Ganges Plain, were Magadha gained prominence, forming the base of the Mauryan Empire, was a distinct cultural area, with new states arising after 500 BCE during the so-called "Second urbanisation". It was influenced by the Vedic culture, but differed markedly from the Kuru-Panchala region. It "was the area of the earliest known cultivation of rice in South Asia and by 1800 BCE was the location of an advanced neolithic population associated with the sites of Chirand and Chechar". In this region the Shramanic movements flourished, and Jainism and Buddhism originated.

Indus Valley Civilization

The Indo-Aryan migration into the northern Punjab started shortly after the decline of the Indus-Valley civilization (IVC). According to the "Aryan Invasion Theory" this decline was caused by "invasions" of barbarich and violent Aryans who conquered the IVC. This "Aryan Invasion Theory" is not supported by the archeological and genetic data, and is not representative of the "Indo-Aryan migration theory."

Decline of Indus Valley Civilisation

The decline of the IVC from about 1900 BC started before the onset of the Indo-Aryan migrations. A regional cultural discontinuity occurred during the second millennium BC and many Indus Valley cities were abandoned during this period, while many new settlements began to appear in Gujarat and East Punjab and other settlements such as in the western Bahawalpur region increased in size.

Jim Shaffer and Lichtenstein contend that in the second millennium BCE considerable "location processes" took place. In the eastern Punjab 79.9% and in Gujarat 96% of sites changed settlement status. According to Shaffer & Lichtenstein,

It is evident that a major geographic population shift accompanied this 2nd millennium BCE localisation process. This shift by Harappan and, perhaps, other Indus Valley cultural mosaic groups, is the only archaeologically documented west-to-east movement of human populations in South Asia before the first half of the first millennium B.C.

Continuity

According to Erdosy, the ancient Harappans were not markedly different from modern populations in Northwestern India and present-day Pakistan. Craniometric data showed similarity with prehistoric peoples of the Iranian plateau and Western Asia, although Mohenjodaro was distinct from the other areas of the Indus Valley.

According to Kennedy, there is no evidence of "demographic disruptions" after the decline of the Harappa culture. Kenoyer notes that no biological evidence can be found for major new populations in post-Harappan communities. Hemphill notes that "patterns of phonetic affinity" between Bactria and the Indus Valley Civilisation are best explained by "a pattern of long-standing, but low-level bidirectional mutual exchange."

According to Kennedy, the Cemetery H culture "shows clear biological affinities" with the earlier population of Harappa. The archaeologist Kenoyer noted that this culture "may only reflect a change in the focus of settlement organization from that which was the pattern of the earlier Harappan phase and not cultural discontinuity, urban decay, invading aliens, or site abandonment, all of which have been suggested in the past." Recent excavations in 2008 at Alamgirpur, Meerut District, appeared to show an overlap between the Harappan and PGW pottery indicating cultural continuity.

Relation with Indo-Aryan migrations

According to Kenoyer, the decline of the Indus Valley Civilisation is not explained by Aryan migrations, which took place after the decline of the Indus Valley Civilisation. Yet, according to Erdosy,

Evidence in material culture for systems collapse, abandonment of old beliefs and large-scale, if localised, population shifts in response to ecological catastrophe in the 2nd millennium B.C. must all now be related to the spread of Indo-Aryan languages.

Erdosy, testing hypotheses derived from linguistic evidence against hypotheses derived from archaeological data, states that there is no evidence of "invasions by a barbaric race enjoying technological and military superiority", but "some support was found in the archaeological record for small-scale migrations from Central to South Asia in the late 3rd/early 2nd millennia BC." According to Erdosy, the postulated movements within Central Asia can be placed within a processional framework, replacing simplistic concepts of "diffusion", "migrations" and "invasions".

Some scholars have argued that the historical Vedic culture is the result of an amalgamation of the immigrating Indo-Aryans with the remnants of the indigenous civilization, such as the Ochre Coloured Pottery culture. Such remnants of IVC culture are not prominent in the Rigveda, with its focus on chariot warfare and nomadic pastoralism in stark contrast with an urban civilization.

Inner Asia - Wusun and Yuezhi

File:Yueh-ChihMigrations.jpg

The migrations of the Yuezhi through Central Asia, from around 176 BCE to 30 CE

According to Christopher I. Beckwith the Wusun, an Indo-European Caucasian people of Inner Asia in antiquity, were also of Indo-Aryan origin. From the Chinese term Wusun, Beckwith reconstructs the Old Chinese *âswin, which he compares to the Old Indic aśvin "the horsemen," the name of the Rigvedic twin equestrian gods. Beckwith suggests that the Wusun were an eastern remnant of the Indo-Aryans, who had been suddenly pushed to the extremeties of the Eurasian Steppe by the Iranian peoples in the 2nd millennium BCE.

The Wusun are first mentioned by Chinese sources as vassals in the Tarim Basin of the Yuezhi, another Indo-European Caucasian people of possible Tocharian stock. Around 175 BCE, the Yuezhi were utterly defeated by the Xiongnu, also former vassals of the Yuezhi. The Yuezhi subsequently attacked the Wusun and killed their king (Kunmo Chinese: 昆彌 or Kunmi Chinese: 昆莫) Nandoumi (Chinese: 難兜靡), capturing the Ili Valley from the Saka (Scythians) shortly afterwards. In return the Wusun settled in the former territories of the Yuezhi as vassals of the Xiongnu.

The son of Nandoumi was adopted by the Xiongnu king and made leader of the Wusun. Around 130 BCE he attacked and utterly defeated the Yuezhi, settling the Wusun in the Ili Valley. After the Yuezhi were defeated by the Xiongnu, in the 2nd century BCE, a small group, known as the Little Yuezhi, fled to the south, while the majority migrated west to the Ili Valley, where they displaced the Sakas (Scythians). Driven from the Ili Valley shortly afterwards by the Wusun, the Yuezhi migrated to Sogdia and then Bactria, where they are often identified with the Tókharoi (Τοχάριοι) and Asioi of Classical sources. They then expanded into northern South Asia, where one branch of the Yuezhi founded the Kushan Empire. The Kushan empire stretched from Turfan in the Tarim Basin to Pataliputra on the Gangetic plain at its greatest extent, and played an important role in the development of the Silk Road and the transmission of Buddhism to China.

Soon after 130 BCE the Wusun became independent of the Xiongnu, becoming trusted vassals of the Han Dynasty and powerful force in the region for centuries. With the emerging steppe federations of the Rouran, the Wusun migrated into the Pamir Mountains in the 5th century CE. They are last mentioned in 938 when a Wusun chieftain paid tribute to the Liao dynasty.

Influence on China

The Indo-European eastward expansion in the 2nd millennium BCE had a significant influence on Chinese culture. It is little doubt that the chariot entered China through the Central Asia and the Northern Steppe, possibly indicating some form of contact with the Indo-Europeans. Recent archaeological finds have shown that the late Shang Dynasty used horses, chariots, bows and practiced horse burials very similar to the steppe peoples to the west. Indo-European technological influence on Chinese culture at the time include the introduction of the domesticated horse, iron technology. and wheeled vehicles Other cultural influences resulting from Indo-European influence include fighting styles, head-and-hoof rituals, art motifs and myths. These significant Indo-European influences on China at the time have led the Sinologist Christopher I. Beckwith to propose that the "idea of writing" in Shang China might have been a result of Indo-European influence, that Indo-Europeans "may even have been responsible for the foundation of the Shang Dynasty," and that Old Chinese of the Oracle bone script contained influences from Indo-European languages. While the Old Chinese word for honey is generally accepted as a loanword from Tocharian, Beckwith suggests that many more Old Chinese words are of Tocharian origin, claiming a similar Indo-European influence on Tibeto-Burman.

Beckwith proposes that the name of the Qiang, the main foreign enemies of the Shang Dynasty, has an Indo-European etymology. From the modern Chinese Qiang (Chinese: 羌; pinyin: Qiāng; Wade–Giles: Ch'iang), Sinologist Edwin G. Pulleyblank reconstructs the Old Chinese *klaŋ, which Beckwith compares to the Tocharian word klānk, meaning "to ride, go by wagon", as in "to ride off to hunt from a chariot", so that Qiang could actually mean "charioteer". The Oracle Bones note that the Qiang were skilled charioteers and makers of Oracle Bones. According to Beckwith, it is possible that the clan (Jiang) of Jiang Yuan, mother of Houji, founder of the Zhou dynasty, which succeeded the Shang, was related or identical to the Qiang.

Pulleyblank has suggested that the Yuezhi, the Wusun the Dayuan, the Kangju and the people of Yanqi, could have been Tocharian-speaking. Of these the Yuezhi are generally held to have been Tocharians. The Yuezhi were originally settled in the arid grasslands of the eastern Tarim Basin area, in what is today Xinjiang and western Gansu, in China. After the Yuezhi were defeated by the Xiongnu, in the 2nd century BCE, a small group, known as the Little Yuezhi, fled to the south, later spawning the Jie people who dominated the Later Zhao until their complete extermination by Ran Min in the Wei–Jie war. The majority of the Yuezhi however migrated west to the Ili Valley, where they displaced the Sakas (Scythians). Driven from the Ili Valley shortly afterwards by the Wusun, the Yuezhi migrated to Sogdia and then Bactria, where they are often identified with the Tókharoi (Τοχάριοι) and Asioi of Classical sources. They then expanded into northern South Asia, where one branch of the Yuezhi founded the Kushan Empire. The Kushan empire stretched from Turfan in the Tarim Basin to Pataliputra on the Gangetic plain at its greatest extent, and played an important role in the development of the Silk Road and the transmission of Buddhism to China. Tocharian languages continued to be spoken in the city-states of the Tarim Basin, only becoming extinct in the Middle Ages.

Second wave - Iranians

The first Iranians to reach the Black Sea may have been the Cimmerians in the 8th century BC, although their linguistic affiliation is uncertain. They were followed by the Scythians, whom would dominate the area, at their height, from the Carpathian Mountains in the west, to the eastern-most fringes of Central Asia in the east. For most of their existence, they were based in what is modern-day Ukraine and southern European Russia. Sarmatian tribes, of whom the best known are the Roxolani (Rhoxolani), Iazyges (Jazyges) and the Alani (Alans), followed the Scythians westwards into Europe in the late centuries BCE and the 1st and 2nd centuries of the Common Era (The Age of Migrations). The populous Sarmatian tribe of the Massagetae, dwelling near the Caspian Sea, were known to the early rulers of Persia in the Achaemenid Period. In the east, the Saka occupied several areas in Xinjiang, from Khotan to Tumshuq.

The Medes, Parthians and Persians begin to appear on the western Iranian plateau from c. 800 BC, after which they remained under Assyrian rule for several centuries, as it was with the rest of the peoples in the Near East. The Achaemenids replaced Median rule from 559 BC. Around the first millennium of the Common Era (AD), the Kambojas, the Pashtuns and the Baloch began to settle on the eastern edge of the Iranian plateau, on the mountainous frontier of northwestern and western Pakistan, displacing the earlier Indo-Aryans from the area.

In Central Asia, the Turkic languages have marginalized Iranian languages as a result of the Turkic expansion of the early centuries AD. In Eastern Europe, Slavic and Germanic peoples assimilated and absorbed the native Iranian languages (Scythian and Sarmatian) of the region. Extant major Iranian languages are Persian, Pashto, Kurdish, and Balochi, besides numerous smaller ones.

Anthropology: elite recruitment and language change

Elite dominance

Small groups can change a larger cultural area, and elite male dominance by small groups may have led to a language shift in northern India. According to Parpola, local elites joined "small but powerfull groups" of Indo-European speaking migrants. These migrants had an attractive social system and good weapons, and luxury goods which marked their status and power. Joining these groups was attractive for local leaders, since it strengthened their position, and gave them additional advantages. These new members were further incorporated by matrimonial alliances.

Renfrew: models of "linguistic replacement"

Basu et al. refer to Renfrew, who described four models for "linguistic replacement":

1. The demographic-subsistence model, exemplified by the process of agricultural dispersal, in which the incoming group has exploitive technologies which makes them dominant. It may lead to significant gene flow, and significant genetic changes in the population. But it may also lead to acculturalisation, in which case the technologies are taken over, but there is less change in the genetic composition of the population;
2. The existence of extended trading systems which lead to the development of a lingua franca, in which case some gene flow is to be expected;
3. The elite dominance model, in which "a relatively small but well-organized group [...] take[s] over the system." Given the small size of the elite, its genetic influence may also be small, though "preferential access to marriage partners" may result in a relatively strong influence on the gene pool. Sexual asymmetry may also be of influence: incoming elites often consist mostly of males, who have no influence on the mitochondrial DNA of the gene pool, but may influence the Y chromosomes of the gene pool;
4. System collapse, in which territorial boundaries are changed, and elite dominance may appear for a while.

David Anthony: elite recruitment

David Anthony, in his "revised Steppe hypothesis" notes that the spread of the Indo-European languages probably did not happen through "chain-type folk migrations," but by the introduction of these languages by ritual and political elites, which are emulated by large groups of people. Anthony gives the example of the Luo-speaking Acholi in northern Uganda in the 17th and 18th century, whose language spread rapidly in the 19th century. Anthony notes that "Indo-European languages probably spread in a similar way among the tribal societies of prehistoric Europe," carried forward by "Indo-European chiefs" and their "ideology of political clientage." Anthony notes that "elite recruitment" may be a suitable term for this system.

Michael Witzel: small groups and acculturation

Michael Witzel refers to Ehret’s model "which stresses the osmosis, or a "billiard ball," or Mallory’s Kulturkugel, effect of cultural transmission." According to Ehret, ethnicity and language can shift with relatively easy in small societies, due to the cultural, economic and military choices made by the local population in question. The group bringing new traits may initially be small, contributing features that can be fewer in number than those of the already local culture. The emerging combined group may then initiate a recurrent, expansionist process of ethnic and language shift.

Witzel notes that "arya/ārya does not mean a particular "people" or even a particular 'racial' group but all those who had joined the tribes speaking Vedic Sanskrit and adhering to their cultural norms (such as ritual, poetry, etc.)." According to Witzel, "there must have been a long period of acculturation between the local population and the "original" immigrants speaking Indo-Aryan." Witzel also notes that the speakers of Indo-Aryan and the local population must have been bilingual, speaking each other's languages and interacting with each other, before the Rg Veda was composed in the Punjab.

Salmons: systematic changes in community structure

Joseph Salmons notes that Anthony presents scrace concrete evidence or arguments. Salmons is critical about the notion of "prestige" as a central factor in the shift to Indo-European languages, referring to Milroy who notes that "prestige" is "a cover term for a variety of very distinct notions." Instead, Milroy offers "arguments built around network structure," though Salmons also notes that Anthony includes several of those arguments, "Including political and technological advantages." According to Salmons, the best model is offered by Fishman, who

... understands shift in terms of geographical, social, and cultural "dislocation" of language communities. Social dislocation, to give the most relevant example, involves "siphoning off the talented, the enterprising, the imaginative and the creative" ([Fishman] 1991: 61), and sounds strikingly like Anthony's 'recruitment' scenario.

Salmons himself argues that

... systematic changes in community structure are what drive language shift, incorporating Milroy's neywork structures as well. The heart of the view is the quintessential element of modernization, namely a shift from local community-internal organization to regional (state or national or international, in modern settings), extra-community organizations. Shift correlates with this move from pre-dominantly 'horizontal' community structures to more 'vertical' ones.

Genetics: ancient ancestry and multiple gene flows

India has one of the most genetically diverse populations in the world, and the history of this genetic diversity is the topic of continued research and debate. The Indo-Aryan migrations form part of a complex genetical puzzle on the origin and spread of the various components of the Indian population, including various waves of admixture and language shift. The genetic impact of the Indo-Aryans may have been marginal, but this is not at odds with the cultural and linguistic influence, since language shift is possible without a change in genetics.

Ancestral groups

Common maternal ancestry

Sahoo et al. (2006) states that "there is general agreement that Indian caste and tribal populations share a common late Pleistocene maternal ancestry in India."

Kivisild et al. (1999) concluded that there is "an extensive deep late Pleistocene genetic link between contemporary Europeans and Indians" via the mitochondrial DNA, that is, DNA which is inherited from the mother. According to them, the two groups split at the time of the peopling of Asia and Eurasia and before modern humans entered Europe. Kivisild et al. (2000) note that "the sum of any recent (the last 15,000 years) western mtDNA gene flow to India comprises, in average, less than 10 per cent of the contemporary Indian mtDNA lineages."

Kivisild et al. (2003) and Sharma (2005) note that north and south Indians share a common maternal ancenstry: Kivisild et al. (2003) further note that "these results show that Indian tribal and caste populations derive largely from the same genetic heritage of Pleistocene southern and western Asians and have received limited gene flow from external regions since the Holocene.

"Ancestral North Indians" and "Ancestral South Indians"

Reich et al. (2009), in a collaborative effort between the Harvard Medical School and the Centre for Cellular and Molecular Biology (CCMB), examined the entire genomes worth 560,000 single nucleotide polymorphisms (SNPs), as compared to 420 SNPs in prior work. They also cross-compared them with the genomes of other regions available in the global genome database. Through this study, they were able to discern two genetic groups in the majority of populations in India, which they called "Ancestral North Indians" (ANI) and "Ancestral South Indians" (ASI). They found that the ANI genes are close to those of Middle Easterners, Central Asians and Europeans whereas the ASI genes are dissimilar to all other known populations outside India. These two distinct groups, which had split ca. 50,000 years ago, formed the basis for the present population of India.

The two groups mixed between 1,900 and 4,200 years ago (100 CE-2200 BCE), where-after a shift to endogamy took place and admixture became rare. Speaking to Fountain Ink, David Reich stated, "Prior to 4,200 years ago, there were unmixed groups in India. Sometime between 1,900 to 4,200 years ago, profound, pervasive convulsive mixture occurred, affecting every Indo-European and Dravidian group in India without exception." Reich pointed out that their work does not show that a substantial migration occurred during this time.

Metspalu et al. (2011), representing a collaboration between the Estonian Biocenter and CCMB, confirmed that the Indian populations are characterized by two major ancestry components. One of them is spread at comparable frequency and haplotype diversity in populations of South and West Asia and the Caucasus. The second component is more restricted to South Asia and accounts for more than 50% of the ancestry in Indian populations. Haplotype diversity associated with these South Asian ancestry components is significantly higher than that of the components dominating the West Eurasian ancestry palette.

Additional components

ArunKumar et al. (2015) discern three major ancestry components, which they call "Southwest Asian," "Southeast Asian" and "Northeast Asian." The Southwest Asian component seems to be a native Indian component, while the Southeast Asian component is related to East Asian populations. Brahmin populations "contained 11.4 and 10.6% of Northern Eurasian and Mediterranean components, thereby suggesting a shared ancestry with the Europeans." They note that this fits with earlier studies which "suggested similar shared ancestries with Europeans and Mediterraneans." They further note that

Studies based on uni-parental marker have shown diverse Y-chromosomal haplogroups making up the Indian gene pool. Many of these Y-chromosomal markers show a strong correlation to the linguistic affiliation of the population. The genome-wide variation of the Indian samples in the present study correlated with the linguistic affiliation of the sample.

They conclude that, while there may have been an ancient settlement in the subcontinent, "male-dominated genetic elements shap[ed] the Indian gene pool," and that these elements "have earlier been correlated to various languages," and further note "the fluidity of female gene pools when in a patriarchal and patrilocal society, such as that of India."

Basu et al. (2016) extend the study of Reich et al. (2009) by postulating two other populations in addition to the ANI and ASI: "Ancestral Austro-Asiatic" (AAA) and "Ancestral Tibeto-Burman" (ATB), corresponding to the Austro-Asiatic and Tibeto-Burman language speakers. According to them, ancestral populations seem to have occupied geographically separated habitats. The ASI and the AAA were early settlers, who possibly arrived via the southern wave out of Africa. The ANI are related to Central South Asians and entered India through the northwest, while the ATB are related to East Asians and entered India through northeast corridors. They further note that

The asymmetry of admixture, with ANI populations providing genomic inputs to tribal populations (AA, Dravidian tribe, and TB) but not vice versa, is consistent with elite dominance and patriarchy. Males from dominant populations, possibly upper castes, with high ANI component, mated outside of their caste, but their offspring were not allowed to be inducted into the caste. This phenomenon has been previously observed as asymmetry in homogeneity of mtDNA and heterogeneity of Y-chromosomal haplotypes in tribal populations of India as well as the African Americans in United States.

Male-mediated migration

Reich et al. (2009), citing Kivisild et al. (1999), indicate that there has been a low influx of female genetic material since 50,000 years ago, but a "male gene flow from groups with more ANI relatedness into ones with less."

ArunKumar et al. (2015) "suggest that ancient male-mediated migratory events and settlement in various regional niches led to the present day scenario and peopling of India."

North-south cline

According to Metspalu et al. (2011) there is "a general principal component cline stretching from Europe to south India." This northwest component is shared with populations from the Middle East, Europe and Central Asia, and is thought to represent at least one ancient influx of people from the northwest. According to Saraswathy et al. (2010), there is "a major genetic contribution from Eurasia to North Indian upper castes" and a "greater genetic inflow among North Indian caste populations than is observed among South Indian caste and tribal populations." According to Basu et al. (2003) and Saraswathy et al. (2010) certain sample populations of upper caste North Indians show a stronger affinity to Central Asian caucasians, whereas southern Indian Brahmins show a less stronger affinity.

Scenarios

While Reich notes that the onset of admixture coincides with the arrival of Indo-European language, according to Metspalu (2011), the commonalities of the ANI with European genes cannot be explained by the influx of Indo-Aryans at ca. 3,500 YBP alone. They state that the split of ASI and ANI predates the Indo-Aryan migration, both of these ancestry components being older than 3,500 YBP." Moorjani (2013) states that "We have further shown that groups with unmixed ANI and ASI ancestry were plausibly living in India until this time." Moorjani (2013) describes three scenarios regarding the bringing together of the two groups:

1. "migrations that occurred prior to the development of agriculture [8,000–9,000 years before present (BP)]. Evidence for this comes from mitochondrial DNA studies, which have shown that the mitochondrial haplogroups (hg U2, U7, and W) that are most closely shared between Indians and West Eurasians diverged about 30,000–40,000 years BP."
2. "Western Asian peoples migrated to India along with the spread of agriculture [...] Any such agriculture related migrations would probably have begun at least 8,000–9,000 years BP (based on the dates for Mehrgarh) and may have continued into the period of the Indus civilization that began around 4,600 years BP and depended upon West Asian crops."
3. "migrations from Western or Central Asia from 3,000 to 4,000 years BP, a time during which it is likely that Indo-European languages began to be spoken in the subcontinent. A difficulty with this theory, however, is that by this time India was a densely populated region with widespread agriculture, so the number of migrants of West Eurasian ancestry must have been extraordinarily large to explain the fact that today about half the ancestry in India derives from the ANI."

Pre-agricultural migrations

Metspalu et al. (2011) detected a genetic component in India, k5, which "distributed across the Indus Valley, Central Asia, and the Caucasus." According to Metspalu et al. (2011), k5 "might represent the genetic vestige of the ANI," though they also note that the geographic cline of this component within India "is very weak, which is unexpected under the ASI-ANI model," explaining that the ASI-ANI model implies an ANI contribution which decreases toward southern India. According to Metspalu et al. (2011), "regardless of where this component was from (the Caucasus, Near East, Indus Valley, or Central Asia), its spread to other regions must have occurred well before our detection limits at 12,500 years." Speaking to Fountain Ink, Metspalu said, "the West Eurasian component in Indians appears to come from a population that diverged genetically from people actually living in Eurasia, and this separation happened at least 12,500 years ago." Moorjani et al. (2013) refer to Metspalu (2011) as "fail[ing] to find any evidence for shared ancestry between the ANI and groups in West Eurasia within the past 12,500 years." CCMB researcher Thangaraj believes that "it was much longer ago," and that "the ANI came to India in a second wave of migration that happened perhaps 40,000 years ago."

Agricultural migrations

Near-Eastern migrations

Kivisild et al. (1999) note that "a small fraction of the 'Caucasoid-specific' mtDNA lineages found in Indian populations can be ascribed to a relatively recent admixture." at ca. 9,300 ± 3,000 years before present, which coincides with "the arrival to India of cereals domesticated in the fertile Crescent" and "lends credence to the suggested linguistic connection between Elamite and Dravidic populations."

According to Gallego Romero et al. (2011), their research on lactose tolerance in India suggests that "the west Eurasian genetic contribution identified by Reich et al. (2009) principally reflects gene flow from Iran and the Middle East." Gallego Romero notes that Indians who are lactose-tolerant show a genetic pattern regarding this tolerance which is "characteristic of the common European mutation." According to Romero, this suggests that "the most common lactose tolerance mutation made a two-way migration out of the Middle East less than 10,000 years ago. While the mutation spread across Europe, another explorer must have brought the mutation eastward to India – likely traveling along the coast of the Persian Gulf where other pockets of the same mutation have been found." In contrast, Allentoft et al. (2015) found that lactose-tolerance was absent in the Yamnaya culture, noting that while "the Yamnaya and these other Bronze Age cultures herded cattle, goats, and sheep, they couldn’t digest raw milk as adults. Lactose tolerance was still rare among Europeans and Asians at the end of the Bronze Age, just 2000 years ago."

According to Lazaridis et al. (2016), "farmers related to those from Iran spread northward into the Eurasian steppe; and people related to both the early farmers of Iran and to the pastoralists of the Eurasian steppe spread eastward into South Asia." They further note that ANI "can be modelled as a mix of ancestry related to both early farmers of western Iran and to people of the Bronze Age Eurasian steppe."

Haplogroup R1a and related haplogroups

File:R1a. Info-19.05.2014.jpg

R1a1a clades

The distribution and proposed origin of haplogroup R1a, more specifically R1a1a1b, is often being used as an argument pro or contra the Indo-Aryan migrations. It is found in high frequencies in Eastern Europe (Z282) and south Asia (Z93), the areas of the Indo-European migrations. The place of origin of this haplogroup may give an indication of the "homeland" of the Indo-Europeans, and the direction of the first migrations.

Cordeaux et al. (2004), based on the spread of a cluster of haplogroups (J2, R1a, R2, and L) in India, with higher rates in northern India, argue that agriculture in south India spread with migrating agriculturalists, which also influenced the genepool in south India.

Sahoo et al. (2006), in response to Cordeaux et al. (2004), suggest that those haplogroups originated in India, based on the spread of these various haplogroups in India. According to Sahoo et al. (2006), this spread "argue[s] against any major influx, from regions north and west of India, of people associated either with the development of agriculture or the spread of the Indo-Aryan language family." They further propose that "the high incidence of R1* and R1a throughout Central Asian and East European populations (without R2 and R* in most cases) is more parsimoniously explained by gene flow in the opposite direction," which according to Sahoo et al. (2006) explains the "sharing of some Y-chromosomal haplogroups between Indian and Central Asian populations."

Sengupta et al. (2006) also comment on Cordeaux et al. (2004), stating that "the influence of Central Asia on the pre-existing gene pool was minor," and arguing for "a peninsular origin of Dravidian speakers than a source with proximity to the Indus and with significant genetic input resulting from demic diffusion associated with agriculture."

Sharma et al. (2009) found a high frequency of R1a1 in India. They therefore argue for an Indian origin of R1a1, and dispute "the origin of Indian higher most castes from Central Asian and Eurasian regions, supporting their origin within the Indian subcontinent."

Underhill et al. (2014/2015) conclude that R1a1a1, the most frequent subclade of R1a, split into Z282 (Europe) and Z93 (Asia) at circe 5,800 before present. According to Underhill et al. (2014/2015), "[t]his suggests the possibility that R1a lineages accompanied demic expansions initiated during the Copper, Bronze, and Iron ages." They further note that the diversification of Z93 and the "early urbanization within the Indus Valley also occurred at this time and the geographic distribution of R1a-M780 (Figure 3d) may reflect this."

Palanichamy et al. (2015), while responding to Cordeaux et al. (2004), Sahoo et al. (2006) and Sengupta et al. (2006), elaborated on Kivisild et al.'s (1999) suggestion that West Eurasian haplogroups "may have been spread by the early Neolithic migrations of proto-Dravidian farmers spreading from the eastern horn of the Fertile Crescent into India." They conclude that "the L1a lineage arrived from western Asia during the Neolithic period and perhaps was associated with the spread of the Dravidian language to India," indicating that "the Dravidian language originated outside India and may have been introduced by pastoralists coming from western Asia (Iran)." They further conclude that two subhalogroups originated with the Dravidian speaking peoples, and may have come to South India when the Dravidian language spread.

Poznik et al. (2016) note that 'striking expansions' occurred within R1a-Z93 at ~4,500-4,000 years ago, which "predates by a few centuries the collapse of the Indus Valley Civilisation." Mascarenhas et al. (2015) note that the expansion of Z93 from Transcaucasia into South Asia is compatible with "the archeological records of eastward expansion of West Asian populations in the 4th millennium BCE culminating in the socalled Kura-Araxes migrations in the post-Uruk IV period."

Indo-European migrations

Genetic impact of Indo-Aryan migrations

The impact, or absence of such an impact, of the Indo-Aryan migrations on the Indian genepool is a matter of ongoing debate.

Zerjal et al. (2002) argue that "multiple recent events" may have reshaped "this genetic landscape."

Bamshad et al. (2001), Wells et al. (2002) and Basu et al. (2003) argue for an influx of Indo-European migrants into the Indian subcontinent, but not necessarily an "invasion of any kind". Bamshad et al. (2001) notice that the correlation between caste-status and West Eurasian DNA may be explained by subsequent male immigration into the Indian subcontinent. Basu et al. (2003) argue that the Indian subcontinent was subjected to a series of Indo-European migrations about 1500 BC.

Metspalu et al. (2011) note that "any nonmarginal migration from Central Asia to South Asia should have also introduced readily apparent signals of East Asian ancestry into India," which is not the case, and conclude that if there was a major migration of Eurasians into India, this happened before the rise of the Yamna culture. Based on Metspalu (2011), Lalji Singh, a co-author of Metspalu, concludes that "[t]here is no genetic evidence that Indo-Aryans invaded or migrated to India".

Moorjani et al. (2013) notes that the period of 4,200-1,900 years BP was a time of dramatic changes in northern India, and coincides with the "likely first appearance of Indo-European languages and Vedic religion in the subcontinent." Moorjani further notes that there must have been multiple waves of admixture, which had more impact on higher-caste and northern Indians and took place more recently. This may be explained by "additional gene flow," related to the spread of languages:

...at least some of the history of population mixture in India is related to the spread of languages in the subcontinent. One possible explanation for the generally younger dates in northern Indians is that after an original mixture event of ANI and ASI that contributed to all present-day Indians, some northern groups received additional gene flow from groups with high proportions of West Eurasian ancestry, bringing down their average mixture date.

Palanichamy et al. (2015), elaborating on Kivisild et al. (1999) conclude that "A large proportion of the west Eurasian mtDNA haplogroups observed among the higher-ranked caste groups, their phylogenetic affinity and age estimate indicate recent Indo-Aryan migration to India from west Asia. According to Palanichamy et al. (2015), "the west Eurasian admixture was restricted to caste rank. It is likely that Indo-Aryan migration has influenced the social stratification in the pre-existing populations and helped in building the Hindu caste system, but it should not be inferred that the contemporary Indian caste groups have directly descended from Indo-Aryan immigrants.

Jones et al. (2015) state that CHG was "a major contributor to the Ancestral North Indian component." According to Jones et al. (2015), it "may be linked with the spread of Indo-European languages," but they also note that "earlier movements associated with other developments such as that of cereal farming and herding are also plausible."

Basu et al. (2016) note that the ANI are inseparable from Central-South Asian populations in present-day Pakistan. They hypothesise that "the root of ANI is in Central Asia."

According to Lazaridis et al. (2016) ANI "can be modelled as a mix of ancestry related to both early farmers of western Iran and to people of the Bronze Age Eurasian steppe."

East-European origins of R1a-Z93

File:R1a1a1 Migrations.jpg

R1a1a1 steppe origins and migrations

Ornella Semino et al. (2000) proposed Ukrainian origins of R1a1, and a postglacial spread of the R1a1 gene during the Late Glacial Maximum, subsequently magnified by the expansion of the Kurgan culture into Europe and eastward. Spencer Wells proposes central Asian origins, suggesting that the distribution and age of R1a1 points to an ancient migration corresponding to the spread by the Kurgan people in their expansion from the Eurasian steppe. According to Pamjav et al. (2012), "Inner and Central Asia is an overlap zone for the R1a1-Z280 and R1a1-Z93 lineages [which] implies that an early differentiation zone of R1a1-M198 conceivably occurred somewhere within the Eurasian Steppes or the Middle East and Caucasus region as they lie between South Asia and Eastern Europe." Silva et al. (2017) state that "the recently refined Y-chromosome tree strongly suggests that R1a is indeed a highly plausible marker for the long-contested Bronze Age spread of Indo-Aryan speakers into South Asia."

Literary research: similarities, geography, and references to migration

Similarities

Mitanni

The oldest inscriptions in Old Indic, the language of the Rig Veda, is found not in India, but in northern Syria in Hittite records regarding one of their neighbors, the Hurrian-speaking Mitanni. In a treaty with the Hittites, the king of Mitanni, after swearing by a series of Hurrian gods, swears by the gods Mitrašil, Uruvanaššil, Indara, and Našatianna, who correspond to the Vedic gods Mitra, Varuṇa, Indra, and Nāsatya (Aśvin). Contemporary equestrian terminology, as recorded in a horse-training manual whose author is identified as "Kikkuli the Mitannian," contains Indo-Aryan loanwords. The personal names and gods of the Mitanni aristocracy also bear significant traces of Indo-Aryan. Because of the association of Indo-Aryan with horsemanship and the Mitanni aristocracy, it is presumed that, after superimposing themselves as rulers on a native Hurrian-speaking population about the 15th-16th centuries BC, Indo-Aryan charioteers were absorbed into the local population and adopted the Hurrian language.

Brentjes argues that there is not a single cultural element of central Asian, eastern European, or Caucasian origin in the Mitannian area; he also associates with an Indo-Aryan presence the peacock motif found in the Middle East from before 1600 BC and quite likely from before 2100 BC.

Most scholars reject the possibility that the Indo-Aryans of Mitanni came from the Indian subcontinent as well as the possibility that the Indo-Aryans of the Indian subcontinent came from the territory of Mitanni, leaving migration from the north the only likely scenario. The presence of some Bactria-Margiana loan words in Mitanni, Old Iranian and Vedic further strengthens this scenario.

Iranian Avesta

The religious practices depicted in the Rgveda and those depicted in the Avesta, the central religious text of Zoroastrianism—the ancient Iranian faith founded by the prophet Zarathustra—have in common the deity Mitra, priests called hotṛ in the Rgveda and zaotar in the Avesta, and the use of a ritual substance that the Rgveda calls soma and the Avesta haoma. However, the Indo-Aryan deva 'god' is cognate with the Iranian daēva 'demon'. Similarly, the Indo-Aryan asura 'name of a particular group of gods' (later on, 'demon') is cognate with the Iranian ahura 'lord, god,' which 19th and early 20th century authors such as Burrow explained as a reflection of religious rivalry between Indo-Aryans and Iranians.

Most linguists such as Burrow argue that the strong similarity between the Avestan language of the Gāthās—the oldest part of the Avesta—and the Vedic Sanskrit of the Rgveda pushes the dating of Zarathustra or at least the Gathas closer to the conventional Rgveda dating of 1500–1200 BC, i.e. 1100 BC, possibly earlier. Boyce concurs with a lower date of 1100 BC and tentatively proposes an upper date of 1500 BC. Gnoli dates the Gathas to around 1000 BC, as does Mallory (1989), with the caveat of a 400-year leeway on either side, i.e. between 1400 and 600 BC. Therefore, the date of the Avesta could also indicate the date of the Rigveda.

There is mention in the Avesta of Airyan Vaejah, one of the '16 the lands of the Aryans'. Gnoli's interpretation of geographic references in the Avesta situates the Airyanem Vaejah in the Hindu Kush. For similar reasons, Boyce excludes places north of the Syr Darya and western Iranian places. With some reservations, Skjaervo concurs that the evidence of the Avestan texts makes it impossible to avoid the conclusion that they were composed somewhere in northeastern Iran. Witzel points to the central Afghan highlands. Humbach derives Vaējah from cognates of the Vedic root "vij," suggesting the region of fast-flowing rivers. Gnoli considers Choresmia (Xvairizem), the lower Oxus region, south of the Aral Sea to be an outlying area in the Avestan world. However, according to Mallory & Mair (2000), the probable homeland of Avestan is, in fact, the area south of the Aral Sea.

Geographical location of Rigvedic rivers

File:IVC Map.png

Cluster of Indus Valley Civilization site along the course of the Indus River in Pakistan. See this ^[archive] for a more detailed map.

The geography of the Rigveda seems to be centered on the land of the seven rivers. While the geography of the Rigvedic rivers is unclear in some of the early books of the Rigveda, the Nadistuti hymn is an important source for the geography of late Rigvedic society.

The Sarasvati River is one of the chief Rigvedic rivers. The Nadistuti hymn in the Rigveda mentions the Sarasvati between the Yamuna in the east and the Sutlej in the west, and later texts like the Brahmanas and Mahabharata mention that the Sarasvati dried up in a desert.

Most scholars agree that at least some of the references to the Sarasvati in the Rigveda refer to the Ghaggar-Hakra River, while the Afghan river Haraxvaiti/Harauvati Helmand is sometimes quoted as the locus of the early Rigvedic river. Whether such a transfer of the name has taken place from the Helmand to the Ghaggar-Hakra is a matter of dispute. Identification of the early Rigvedic Sarasvati with the Ghaggar-Hakra before its assumed drying up early in the second millennium would place the Rigveda BC, well outside the range commonly assumed by Indo-Aryan migration theory.

A non-Indo-Aryan substratum in the river-names and place-names of the Rigvedic homeland would support an external origin of the Indo-Aryans. However, most place-names in the Rigveda and the vast majority of the river-names in the north-west of South Asia are Indo-Aryan. Non-Indo-Aryan names are, however, frequent in the Ghaggar and Kabul River areas, the first being a post-Harappan stronghold of Indus populations.

Textual references to migrations

Rigveda

File:Late Vedic Culture (1100-500 BCE).png

Probable geographic expansion of late Vedic culture.

Just as the Avesta does not mention an external homeland of the Zoroastrians, the Rigveda does not explicitly refer to an external homeland or to a migration. Later Hindu texts, such as the Brahmanas, Mahabharata, Ramayana, and Puranas, are centered in the Ganges region (rather than Haryana and the Punjab) and mention regions still further to the south and east, suggesting a later movement or expansion of the Vedic religion and culture to the east. There is no clear indication of general movement in either direction in the Rigveda itself; searching for indirect references in the text, or by correlating geographic references with the proposed order of composition of its hymns, has not led to any consensus on the issue.

Srauta Sutra of Baudhayana

According to Romila Thapar, the Srauta Sutra of Baudhayana "refers to the Parasus and the arattas who stayed behind and others who moved eastwards to the middle Ganges valley and the places equivalent such as the Kasi, the Videhas and the Kuru Pancalas, and so on. In fact, when one looks for them, there are evidence for migration."

Later Vedic and Hindu texts

Texts like the Puranas and Mahabharata belong to a much later period than the Rigveda, making their evidence less than sufficient to be used for or against the Indo-Aryan migration theory.

Later Vedic texts show a shift of location from the Panjab to the East. According to the Yajur Veda, Yajnavalkya (a Vedic ritualist and philosopher) lived in the eastern region of Mithila. Aitareya Brahmana 33.6.1. records that Vishvamitra's sons migrated to the north, and in Shatapatha Brahmana 1:2:4:10 the Asuras were driven to the north. In much later texts, Manu was said to be a king from Dravida. In the legend of the flood he stranded with his ship in Northwestern India or the Himalayas. The Vedic lands (e.g. Aryavarta, Brahmavarta) are located in Northern India or at the Sarasvati and Drsadvati River. However, in a post-Vedic text the Mahabharata Udyoga Parva (108), the East is described as the homeland of the Vedic culture, where "the divine Creator of the universe first sang the Vedas." The legends of Ikshvaku, Sumati and other Hindu legends may have their origin in South-East Asia.

The Puranas record that Yayati left Prayag (confluence of the Ganges & Yamuna) and conquered the region of Sapta Sindhu. His five sons Yadu, Druhyu, Puru, Anu and Turvashu correspond to the main tribes of the Rigveda.

The Puranas also record that the Druhyus were driven out of the land of the seven rivers by Mandhatr and that their next king Gandhara settled in a north-western region which became known as Gandhara. The sons of the later Druhyu king Pracetas are supposed by some to have 'migrated' to the region north of Afghanistan though the Puranic texts only speak of an "adjacent" settlement.

Controversy

The debate about the origin of Indo-Aryan peoples is controversial in the Indian subcontinent. It is seen as an oppressive colonial construct, which undermines Indian narratives of the ancientness and indigenous origins of Indian people, language, culture and religion. The theory has been increasingly criticised in India with the growing popularity of Hindutva-politics in the 1990s.

"Indigenous Aryans"

Opponents of the Indo-Aryan migration theory question it and instead promote the notion of Indigenous Aryans, which claims that speakers of Indo-Iranian languages (sometimes called Aryan languages) are "indigenous" to the Indian subcontinent. Within India, several such alternative ideas of the origins of the Indo-Iranian languages and cultures have been developed that purport to show indigenous origins. They are rejected by mainstream scholars, who point out that they neglect linguistic research, and are contradicted by a broad range of research on Indo-European migration.

The proposed "Indigenous Aryans" scenario is based on specific interpretations of archaeological, genetic, and linguistic data and on literary interpretations of the Rigveda. Standard arguments supporting the "Indigenous Aryans" theory or opposing the mainstream Indo-Aryan migration theory include the following:

• Questioning the Indo-Aryan migration theory:

• Presenting the Indo-Aryan migration theory as an "Indo-Aryan invasion theory";
• Questioning the methodology of linguistics;
• Reinterpretation of the linguistic data, arguing for the ancient, indigenous origins of Sanskrit;
• Pointing to the supposed lack of genetic and archaeological evidence to support such an "invasion" into North West India;
• Contesting the possibility that small groups can change culture and languages in a major way;

• Redating India's chronology, re-establishing the Vedic-Puranic chronology:

• Dating the Rg Veda and the Vedic people to the 3rd millennium BCE or earlier;
• Identifying the Sarasvati River with the Ghaggar-Hakra River, which dried-up at ca. 2000 BCE;
• Identifying the Vedic people with the Harappan Civilisation;
• Equating the Harappan Civilisation, Vedic Culture and the Vedic-Puranic chronology.

Mainstream scholarship refuse to accept these argumentsfn|Witzel|2001}}

Hindu nationalism

Nationalistic movements in India oppose the idea that Hinduism has partly endogenous origins. For the founders of the contemporary Hindutva movement, the Aryan migration theory presented a problem. The Hindutva-notion that the Hindu-culture originated in India was threatened by the notion that the Aryans originated outside India. Later Indian writers regarded the Aryan migration theory to be a product of colonialism, aimed to denigrate Hindus. According to them, Hindus had existed in India from times immemorial, as expressed by M. S. Golwalkar:

Undoubtedly ... we Hindus have been in undisputed and undisturbed possession of this land for over 8 or even 10 thousand years before the land was invaded by any foreign race. (Golwakar [1939] 1944)

Racism

The debate inflamed issues around racism and the idea of race, as the origin of the theory was intertwined with the desire of many in the Western world to find the origin of a pure Aryan race, the division of castes by racial basis, and the idea of an Indo-Aryan and Dravidian relating to language families rather than race.

Dalit response

The Dalit and Self-Respect Movement bases much of its identity on the idea of the indigenous origin of Dalits as opposed to transgressing Indo-Aryans.
