During the early to mid 12th century, the Kingdom of Champa and Khmer Empire intermittently warred over territory and influence in Southeast Asia.
During the revolt, Harivarman, known as his formal name Sivänandana, a noble from Panduranga, became the de facto leader of the rebel forces.
[8][6] In 1150 he defeated the combined army of Dai Viet lend troops and his rebelling brother-in-law Vamsaraja's forces at the Battle of Mỹ Sơn.
In addition to his military campaigns, Harivarman refurbished the temple complex at Po Nagar.
[9] In religious imagery, Harivarman depicted himself as an avatar of the semi-divine Cham ancestor Uroja, and claimed to be a reincarnation of four previous kings.
