The term Ahir is derived from Abhira, a clan mentioned several times in inscriptions and Hindu revered books. The term Ahir is often seen as synonymous with Yadav.[1][2] The Mahabharata and other authori-tative works use the three terms-Ahir, Yadav and Gopa synonymous.[3][4]
However, most books publiced as recently as 2001, 2005, propagates the dubious theories generated based on old new paper articles and court records, that present day Yadav caste is merely renamed Ahirs who switched their identity in 1922 to Yadav as part of Sanskritization movement of certain Hindu castes. The facts mentioned in the Ahir taken a false identity of Yadav is incorrect. And these false informations are propagated in recently published books, which no authority in subject. The book contents are based on news paper articles and courts records, whose validities are as genuine as a lawyer's statement.
The British census in 1881, half century before any Sanskritization movement, the census mentions Yadavs as Ahirs. It says "The Yadavs, who in their turn are identified with the Ahirs and Gaolis, were the dominant race at that time.[5]
Hemachandra, in the Dyashraya-Kavya, describe the Ahir King Graharipu, ruling at Vanthali near Junagadh, as an Ahir and a Yadav. Again, many remains of Khandesh (historical stronghold of Ahirs) are popularly believed to be of Gawli Raj, which archaeologically belongs to the Yadvas of Devgiri. Hence, it is concluded that Yadavs of Devagiri were actually Ahirs. This receives some support from the fact that Yaduvanshis even now are one of the most important sub-divisions of the Ahirs.[6]
According to Historian T Padmaja, the Ahirs migrated to Tamil Nadu and established their kingdoms and in inscriptions these Ahirs mention they are from Yadav lineage.[7]
