Yadu (legendary king)

Yadu (यदु) is the founder of the Yadu dynasty in Hinduism. He is described to be the eldest son of King Yayati, and his queen, Devayani. He married five daughters of Nāga king.

Legend
According to a narrative found in the Mahabharata, and the Vishnu Purana, Yadu refused to exchange his years of youth with his father, Yayati, when the latter was cursed with senility by his father-in-law, Shukra. Thus, he was cursed by Yayati to have his progeny disinherited of the dominion. Due to this proclamation, Yadu was replaced by his half-brother, Puru, as the heir to the throne of the Chandravamsha dynasty. Yadu founded his own cadet branch of the dynasty, called the Yaduvamsha.

Descendants
The Agni Purana states that Yadu's lineage was continued by his eldest son, Sahasrajit. Sahasrajit had three sons: Haihaya, Renuhaya, and Haya.

A historical dynasty called the Traikutaka claimed descent from Haihaya.

According to Historian T Padmaja, the Ahirs migrated to Tamil Nadu and established their kingdoms and in inscriptions these Ahirs mention they are from Yadu lineage.

By the 1910s, Goalas, Ahirs, Gops, Gopals, and Sadgops were claiming descent from Yadu under a newly-claimed Yadav identity.
