Chedi Kingdom
Shishupala was the malevolent son of the King Damaghosha (1,189). He had another name viz Sunitha. His mother was Shrutakirti, who was the sister of Kunti, the mother of Pandavas. Both Kunti and Shrutakirti were sisters of Vasudeva the father of Vasudeva Krishna. However Shishupala developed enmity with Krishna (2,44), though he was affectionate to the Pandava Bhima. During his military campaign to collect tribute for Pandava king Yudhishthira's Rajasuya sacrifice, Bhima stayed at the palace of Shishupala for a month as a guest.  He also accepted Yudhishthira's sway over his kingdom and gave Bhima tribute (2,28). During the midst of Yudhishthira's Rajasuya ceremony, a dispute arose between Shishupala and Vasudeva Krishna. Pandavas tried to mediate. He also rebuked the Pandavas and Kuru grandsire Bhishma along with Krishna. Then Krishna, extremely provoked, decapitated Shishupala. (2,44).
