Yadu was the progenitor of the race to which Sri Krishna belonged. The Yadavas descended from Yadu. Yadu was the eldest son of Yayati and Devayani, daughter of Shukracharya. Yaduvamsa or Yadukula belongs to the lunar race.
The eldest son of Yadu was Sahasrajit. The ninth generation from him was Kartavirya Arjuna.
Krostu was Yadu’s second don. Vrishni, Madhu and Sattvata were some of the well-known descendents of Yadu lineage through Krostu.
Since Lord Krishna was a descendant of this branch of the family, he was known as Yadava, Varshneya, Madhava and Sattvata.
