Indo-Aryan peoples
The theory propounded by German comparative philologists in the 1840s and 1850s "maintained that the speakers of Indo-European languages in India, Persia, and Europe were of the same culture and race." This led to a distinction between the Indo-Aryan peoples of northern India and the Dravidian peoples, located mostly in southern India with pockets in the Baluchistan Province in the northwest and in the eastern corner of the Bihar Province.
