This is a list of ancient Indo-Aryan peoples and tribes that are mentioned in the literature of Indian religions.
From the second or first millennium BCE, ancient Indo-Aryan peoples and tribes turned into most of the population in the northern part of the Indian subcontinent – Indus Valley (roughly today's Pakistani Punjab and Sindh), Western India, Northern India, Central India, Eastern India and also in areas of the southern part like Sri Lanka and the Maldives through and after a complex process of migration, assimilation of other peoples and language shift.
