Gomanta

 

The Yadavas of Mathura, the capital of Surasena Kingdom, fled from there due to the continuous attack of Magadha king Jarasandha. They have reached as far south as Gomanta, the modern Indian state called Goa.

He attacked the kinsmen of Krishna. The Surasena Yadavas, consisting of the eighteen younger branches of the Yadavas with their 18000 brothers and cousins, arrived at the conclusion that even if they fight continually they still could be unable to do anything unto Jarasandha even in 300 years. They fled from Mathura, towards west. They rebuilt the old town of Kusasthali(see:Cortalim), and renamed it Dwaraka. It was a Yadava stronghold.

Yet, due to the oppressions of Jarasandha, Yadavas where obliged to migrate further south, to the mountains of Gomanta, measuring three Yojanas (a unit of length) in length. Within each yojana were established, 21 posts of armed men. And at intervals of each yojana were 100 gates with arches which were defended by valiant heroes engaged in guarding them. Innumerable Kshatriyas invincible in war, belonging to the eighteen younger branches of the Yadavas, were employed in defending these works. (2,14)

Bhoja Dynasty that ruled Goa from at least 3rd century AD to the 6th century AD are sometime identified as descendants of the Yadavas, and are also mentioned in Bhavishya Purana.
