Kamsa was the tyrant ruler of the Vrishni kingdom, with its capital at Mathura. He is variously described in Hindu literature as either a human or an asura; The Puranas describe him as an asura, while the Harivamśa describes him as an asura reborn in the body of a man. His royal house was called Bhoja; thus, another of his names was Bhojapati. He was the cousin of Devaki, the mother of the deity Krishna; Krishna ultimately fulfilled a prophecy by slaying Kamsa.
