Indo-Aryan peoples, also known as Indic peoples, are a diverse collection of peoples predominantly found in South Asia, who (traditionally) speak Indo-Aryan languages. Historically, Aryans were the pastoralists who spoke Indo-Iranian languages, migrated from Central Asia into South Asia, and introduced the Proto-Indo-Aryan language. The early Indo-Aryan peoples were known to be closely related to the Iranian group that have resided west of the Indus River; an evident connection in cultural, linguistic, and historical ties. Today, Indo-Aryan speakers are found south of the Indus, across the modern-day regions of Bangladesh, Nepal, Pakistan (east of Indus River), Sri Lanka, Maldives and northern half of India.
