Jayavarman II (802–835) is widely regarded as a king who set the foundations of the Angkor period in Cambodian history, beginning with a grandiose consecration ritual that he conducted in 802 on the sacred Mount Mahendraparvata, now known as Phnom Kulen, to celebrate the independence of Kambuja from a place inscriptions call "Java" At that ceremony Prince Jayavarman II was proclaimed a universal monarch (Cambodian: "Kamraten jagad ta Raja") or God King (Sanskrit: "Deva Raja"). He declared himself Chakravartin in a ritual taken from the Hindu tradition, thereby not only becoming the divinely appointed and therefore uncontested ruler, but also simultaneously declaring the independence of his kingdom from Java. According to some sources, Jayavarman II had resided for some time in Java during the reign of Sailendras, or "The Lords of Mountains", hence the concept of Deva Raja or God King was ostensibly imported from Java. At that time, Sailendras allegedly ruled over Java, Sumatra, the Malay Peninsula and parts of Cambodia, around the Mekong delta.
