In 1190, the Khmer king Jayavarman VII appointed a Cham prince named Vidyanandana, who had defected to Jayavarman in 1182 and had been educated at Angkor, to lead the Khmer army. Vidyanandana defeated the Chams, and proceeded to occupy Vijaya and captured Jaya Indravarman IV, whom he sent back to Angkor as a prisoner.^[43] Adopting the title of Shri Suryavarmadeva (or Suryavarman), Vidyanandana made himself king of Panduranga, which became a Khmer vassal. He made Prince In, a brother-in-law of Jayavarman VII, "King Suryajayavarmadeva in the Nagara of Vijaya" (or Suryajayavarman). In 1191, a revolt at Vijaya drove Suryajayavarman back to Cambodia and enthroned Jaya Indravarman V. Vidyanandana, assisted by Jayavarman VII, retook Vijaya, killing both Jaya Indravarman IV and Jaya Indravarman V, then "reigned without opposition over the Kingdom of Champa,"^[44] declaring his independence from the Khmer Empire. Jayavarman VII responded by launching several invasions of Champa in 1192, 1195, 1198–1199, 1201-1203. Khmer armies under Jayavarman VII continued campaigning against Champa until the Chams were finally defeated in 1203.^[45] A Cham renegade-Prince ong Dhanapatigräma, overthrew and expelled his ruling nephew Vidyanandana to Dai Viet, completing the Khmer conquest of Champa.^[46] From 1203 to 1220, Champa as a Khmer province was ruled by a puppet government led by either ong Dhanapatigräma and then prince Angsaräja, son of Harivarman I. In 1207, Angsaräja accompanied a Khmer army with Burmese and Siamese mercenacy contingents to battle against the Yvan (Dai Viet) army.^[47] Following the dwindling Khmer military presence and voluntary Khmer evacuation of Champa in 1220, Angsaräja took over the reins of government peacefully, proclaiming himself Jaya Paramesvaravarman II, and restored Champa's independence.^[48]
