In the Mahabharata, Dwaraka meaning "the many-gated (city)".Sometimes transcribed as Dwaravati is the capital of the Yadus who ruled the Anarta Kingdom. The city was situated on the western point of Gujarat, and is submerged in the sea as per the volume 16 of the epic Mahabharata.
It was founded by a clan of Yadu chiefs who fled from the Surasena Kingdom to lead a peaceful life which they can't have if they remain in Surasena kingdom because of king Jarasandha of Magadha.
