What is "vidyanandana"

Vidyanandana, Shri Suryavarmadeva, or Suryavarman, was a Cham prince in Cambodia, who in 1182 put down a revolt that broke out at Malyang against Jayavarman VII. He arrived in Jayavarman VII's court in 1182 from Tumpraukvijaya, and was educated as a prince "in all branches of knowledge and all weapons". In 1190 he took part in the war against Champa and seized the capital Vijaya, capturing King Jaya Indravarman IV. Adopting the title of Shri Suryavarmadeva, he made himself king of Panduranga. 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 Viajaya drove Suryajayavarman back to Cambodia and enthroned Jaya Indravarman V. Vidyanandana revolted against Cambodia, occupied Viajaya, killed both Jaya Indravarman IV and Jaya Indravarman V, then "reigned without opposition over the Kingdom of Champa."

Suryavarman sent an embassy to the Dai Viet in 1194 and was recognized by emperor Lý Cao Tông in 1199. He resisted many attempts by Cambodia to dislodge him, until he was defeated by his paternal uncle, Yuvaraja Mnagahna On Dhanapati Grama. In 1203 he was expelled from Champa, sought refuge in Cửa Lò, but departed by sea, and disappeared without a trace.
