Abhira
According to a theory advanced by A. P. Karmakar, Abhiras were a Proto-Dravidian tribe, derived from Dravidian Ayir, which means cowherd. He concludes from the Padma Purana, where Vishnu informed Abhiras, "I shall be born among you, O Abhiras, at Mathura in my eighth birth". D. R. Bhandarkar supports the non-Aryan origin theory, directly relating Krishna to Rig Veda's "Krishna Drapsah", where he fights the Aryan god Indra. Abhiras were the people of Yadava community. Yadu was the eldest son of Yayati and Devyani, who was the daughter of Shukracharya. All the territory of Mathura belonged to Abhiras. Further, Mahabharata describes Abhira as forming one of the seven republics, Samsaptak Gunas, and as a friend of Matsyas, a pre-vedic tribe.
