Ugrasena

thumb|Balarama and [[Krishna being received at the court of the King Ugrasena at Mathura]] Ugrasena () is a character mentioned in the Hindu epic, Mahabharata. He is the King of Mathura, a kingdom that was established by the Vrishni tribes from the Yadavamsha clan. His son Kamsa was a cousin of Krishna's mother, Devaki. King Ugrasena was overthrown by Kamsa, and was sentenced to life in prison, along with Kamsa's cousin, Devaki, and her husband, Vasudeva. Krishna reinstalled Ugrasena as the ruler of Mathura once more after defeating his wicked uncle.

== History == According to the Puranas, Kamsa issued an order for the execution of his own father once he grew paranoid of the valour of Krishna and Balarama in Mathura, observing them slay wild elephants that he had released for their murder. He ordered his father to be thrown in the river Kalindi, bound hand and foot. This was among the many reasons that would lead to his nephew slaying him.
