What are the resons for migration of aryans to gangatic place |
|
Answer» Indo-Aryan migration models[note 1] discuss scenarios around the theory of an origin from outside the Indian subcontinent of Indo-Aryan peoples, an ascribed ethnolinguistic group that spoke Indo-Aryan languages, the predominant languages of North India. Proponents of Indo-Aryan origin outside of the Indian subcontinent generally consider migrations into the region and Anatolia (ancient Mitanni) from Central Asia to have started around 1500 BCE, as a slow diffusion during the Late Harappan period, which led to a language shift in the northern Indian subcontinent. The Iranian languages were brought into Iran by the Iranians, who were closely related to the Indo-Aryans. The Proto-Indo-Iranians, from which the Indo-Aryans and the Iranians developed, formed as a distinguishable culture on the Central Asian steppes north of the Caspian Sea as the Sintashta culture (2100–1800 BCE)[2][3][4] in present-day Russia and Kazakhstan, and developed further as the Andronovo culture (1800–1400 BCE),[5] around the Aral Sea. The proto-Indo-Iranians then migrated southwards to the Bactria-Margiana Culture, from which they borrowed their distinctive religious beliefs and practices. The Indo-Aryans split off around 1800–1600 BCE from the Iranians,[6] whereafter the Indo-Aryans migrated into Anatolia and the northern part of the South Asia (modern Afghanistan, Bangladesh, India, PAKISTAN and Nepal), while the Iranians moved into Iran, both bringing with them the Indo-Iranian languages. Migration by an Indo-European people was first hypothesized in the late 18th century, following the discovery of the Indo-European language family, when similarities between western and Indian languages had been noted. Given these similarities, a single source or origin was proposed, which was diffused by migrations from some original homeland. This linguistic argument is supported by archeological, anthropological, genetical, literary and ecological research. Genetic research reveals that those migrations form part of a complex genetic puzzle on the origin and spread of the various components of the Indian population. Literary research reveals similarities between various, geographically distinct, Indo-Aryan historical cultures. Ecological STUDIES reveal that in the second millennium BCE widespread aridization lead to water shortages and ecological changes in both the Eurasian steppes and the Indian subcontinent,[web 1] CAUSING the collapse of sedentary urban cultures in south central Asia, Afghanistan, Iran, and India, and triggering large-scale migrations, resulting in the merger of migrating peoples with the post-urban cultures.[web 1] The Indo-Aryan migrations started in approximately 1800 BCE, after the invention of the WAR chariot, and also brought Indo-Aryan languages into the Levant and POSSIBLY Inner Asia. It was part of the diffusion of Indo-European languages from the proto-Indo-European homeland at the Pontic–Caspian steppe, a large area of grasslands in far Eastern Europe, which started in the 5th to 4th millennia BCE, and the Indo-European migrations out of the Eurasian Steppes, which started approximately in 2000 BCE.[7][1] The theory posits that these Indo-Aryan speaking people may have been a genetically diverse group of people who were united by shared cultural norms and language, referred to as aryā, "noble". 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. pls mark me as brainliest |
