Nanda

Nanda (also known as Mandaladhish Nanda Rai or Nanda Baba), according to the "Harivamsha" and the "Puranas", was the head of the Gopas tribe of Yadava cowherds referred as "Holy Gwals". Nanda was a Kshatriya and a King. He is popularly known as the foster-father of Krishna. Nandvanshi Ahirs are descendants of Nanda. 
Nanda was the Chief or Mandaladhish of Gokul Mandal that was one of the most powerful Divisional area of Yadava. Nanda was brother (cousin) of King Vasudeva. Vasudeva, took his new-born son Krishna to Nanda on the night of the child's birth so that Nanda could raise him. Nanda, who was married to Yasoda, brought up both Krishna and Balarama. Krishna derives his name "Nandanandana" (meaning son of Nanda) from him.
