Ujung Kulon Kingdom is located in the Ujung Kulon region and was founded by Senapati Bahadura Harigana Jayasakti (Dewawarman I's younger brother). When this kingdom was led by Darma Satyanagara, the king married the daughter of Dewawarman III and later became the 4th king in the Kingdom of Salakanagara. When Tarumanagara grew into a large kingdom, Purnawarman (the third Tarumanagara king) conquered the Ujung Kulon Kingdom. Eventually Ujung Kulon Kingdom became the subordinate kingdom of Tarumanagara. More than that, the Ujung Kulon Royal troops also helped the troops of Wisnuwarman (the fourth king of Tarumanagara) to quell the Cakrawarman rebellion.
