Ahir
The Ahir or Abhir (also transliterated as Aheer and Abhira) also called Yaduvanshi is an Yadav caste found in India and Nepal, They consider themselves descendants of Krishna of the Yaduvamsha and traditionally call themselves Yaduvanshi and use their surname Yadav. The Ahir word is derived from the Sanskrit word Abhira which means Fearless or Cowherd (Gopa), who were once found in different parts of India and Nepal, and who wielded political power in several places. The Abhiras are equated with Ahirs, Gopas and Gollas, and all of them are considered Yadavas. It appears, Ahir caste believes that their dynasty is derived from Yadu dynasty, meanwhile Day (12) points out that 'Bishwaparwa' mythology of Mahabharata (it is a section of sacred text 'Mahabharata') reveals that the second name of 'Yadu' was Ahir because he killed 'Ahi' (snake). Madhu say all the territory of Mathura belongs to Abhira (Ahir and the Abhira often used synonymously).
