Among the problems that have since arisen, one is related to the established view that the Indo-Aryan speaking people came from across the northwestern borders and settled in north India. It was earlier believed that this took the form of an invasion, a theory that few would support today. But that they came as migrants has been endorsed by many scholars. However, the demands of exclusionist national ideologies, the world over, require that the founders of their histories be indigenous. Hence the attempts that are being made to prove this for the Aryans in India.
