Quote: "In a not dissimilar way the various cow-keeping castes of northern India were combining in 1931 to use the common term of Yadava for their various castes, Ahir, Goala, Gopa, etc., and to claim a Rajput origin of extremely doubtful authenticity."
Christophe Jaffrelot (2003) (in en). India's silent revolution: the rise of the lower castes in North India. London: C. Hurst & Co.. பக். 187-188. பன்னாட்டுத் தரப்புத்தக எண்:978-1-85065-670-8. https://books.google.com/books?id=OAkW94DtUMAC. "[187] The term "Yadav" covers many castes which initially had different names: Ahir in the Hindi belt, Punjab and Gujarat, Gavli in Maharashtra, Gola in Andhra Pradesh and Karnataka etc. Their traditional common function, all over India, was that of herdsman, cowherds and milksellers. [188] In practice, the Yadavs today spend most of their time tilling the land. At the turn of the century in the Central Provinces two-thirds of Ahirs were already cultivators and labourers while less than one third raised cattle and dealt with milk and milk products."
