The Vrishnis (Brahmi: vri-shņi) were an ancient Vedic Indian Pastoral-Cowherd Tribe who were believed to be the descendants of Vrishni. It is believed that Vrishni was the son of Satvata, a descendant of Yadu, the son of Yayati. He had two wives, Gandhari and Madri. He has a son named Devamidhusha by his wife Madri. Vasudeva, the father of Krishna was the grandson of Devamidhusha. According to the Puranas, the Vrishnis were residents of Dvaraka.
Jarasandha, father-in-law of Kamsa, invaded Mathura with a vast army; and though Krishna destroyed his army of demons, another asura, Kalayavan by name, surrounded Mathura with another army of thirty million monstrous fiends. Then Krishna thought it well to depart to Dwaraka.
After the death of Duryodhana in Mahabharata, Krishna received the curse of Gandhari. She bewailed the death of her son and of friend and foe; then recognizing Hari as the Prime Mover, the One behind All, she cursed him for letting such things befall. This was her curse: that after 36 years Krishna should perish alone miserably and his people, the Vrishnis, should be destroyed. These things in due time came to pass. A madness seized the people of Dwaraka so that they fell upon one another and were slain, together with all sons and grandsons of Krishna. Only the women and Krishna and Balarama remained alive. Then Balarama went to the forest, and Krishna first sent a messenger to the Kuru city, to place the city and women of Dwaraka under the Pandavas protection, and then took leave of his father; afterward he himself sought the forest, where Balarama awaited him. Krishna discovered his brother seated under a mighty tree on the edge of the forest; he sat like a yogi, and behold, there came forth from his mouth a mighty snake, the thousand headed naga, Ananta, and glided away to ocean. Ocean himself and the sacred rivers and many divine nagas came to meet him. Thus Krishna beheld his brother depart from human world, and he wandered alone in forest.
