Differing theories about the Indo-Aryans and the origins of Vedic culture exist.
Last Updated: 27 Jan. 2014
There are several conflicting theories about the Indo -Aryans who spoke the Sanskrit language and the origins of Vedic culture. These fall into two broad categories: (1) The Indo-Aryans migrated into the subcontinent (either through invasion or peacefully) and eventually merged with the local Indus valley population or (2) They were already a part of the indigenous population and the ensuing Vedic culture emerged through series of cultural transformations.
A popular theory is that the Indo-Aryans were a group of warrior nomads and cattle breeders who migrated from Central Asia between 2000 to 1500 BC passing through Iran and Turkey into what is modern day Pakistan. They moved in small groups over time and initially settled along the Swat, Gomal, Kurram, and Kabul Rivers. In line with this theory it is believed that Aryans encountered the people of the Indus Valley Civilization from whom they learned about farming techniques. Eventually the Aryans took over farm and grazing lands, as they had weapons, metal armor and horse drawn chariots. As time passed, the Aryans settled down to become an agrarian people. Support for this theory comes from archeological evidence, bronze and copper tools and weapons, found in this region with striking similarities to those found in Tajikistan and Uzbekistan.
Another theory is that there was no migration or invasion rather the Indo-Aryans were originally a part of the indigenous population. Vedic culture emerged through a process of several cultural transformations or adjustments. This is supported by what appears to be lack of evidence of an Aryan conquest such as the remains of horses and chariots.
