Indo-Aryan peoples are a diverse collection of Indo-European peoples speaking Indo-Aryan languages in the Indian subcontinent. Historically, Aryans were the Indo-Iranian speaking pastoralists who migrated from Central Asia into South Asia and introduced the Proto-Indo-Aryan language. Today, the Indo-Aryan language speakers are found across the modern-day regions of Bangladesh, Nepal, eastern-Pakistan, Sri Lanka, Maldives and northern-India.
History
Proto-Indo-Iranians
The introduction of the Indo-Aryan languages in the Indian subcontinent was the result of a migration of Indo-Aryan people from Central Asia into the northern Indian subcontinent (modern-day Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka). These migrations started approximately 1,800 BCE, after the invention of the war chariot, and also brought Indo-Aryan languages into the Levant and possibly Inner Asia. Another group of the Indo-Aryans migrated further westward and founded the Mitanni kingdom in northern Syria; (c. 1500–1300 BC) the other group were the Vedic people. Christopher I. Beckwith suggests that the Wusun, an Indo-European Caucasoid people of Inner Asia in antiquity, were also of Indo-Aryan origin.
The Proto-Indo-Iranians, from which the Indo-Aryans developed, are identified with the Sintashta culture (2100–1800 BCE), and the Andronovo culture, which flourished ca. 1800–1400 BCE in the steppes around the Aral Sea, present-day Kazakhstan, Turkmenistan, and Uzbekistan. The Proto-Indo-Aryan split off around 1800–1600 BCE from the Iranians, moved south through the Bactria-Margiana Culture, south of the Andronovo culture, borrowing some of their distinctive religious beliefs and practices from the BMAC, and then migrated further south into the Levant and north-western India. The migration of the Indo-Aryans was part of the larger diffusion of Indo-European languages from the Proto-Indo-European homeland at the Pontic–Caspian steppe which started in the 4th millennia BCE. The GGC, Cemetery H, Copper Hoard, OCP, and PGW cultures are candidates for cultures associated with Indo-Aryans.
The Indo-Aryans were united by shared cultural norms and language, referred to as aryā 'noble'. Over the last four millennia, the Indo-Aryan culture has evolved particularly inside India itself, but its origins are in the conflation of values and heritage of the Indo-Aryan and indigenous people groups of India. Diffusion of this culture and language took place by patron-client systems, which allowed for the absorption and acculturation of other groups into this culture, and explains the strong influence on other cultures with which it interacted.
While the Indo-Aryan linguistic group occupies mainly northern parts of India, genetically, all South Asians across the Indian subcontinent are descendants of a mix of South Asian hunter-gatherers, Iranian hunter-gatherers, and Central Asian steppe pastoralists in varying proportion. Additionally, Austroasiatic and Tibeto-Burmese speaking people contributed to the genetic make-up of South Asia.
Indigenous Aryanism propagates the idea that the Indo-Aryans were indigenous to the Indian subcontinent, and that the Indo-European languages spread from there to central Asia and Europe. Contemporary support for this idea is ideologically driven, and has no basis in objective data and mainstream scholarship.
