What happened
In 802, a Khmer leader named Jayavarman II, who inscriptions say had returned from exile in a place called Java, held a consecration ceremony on Phnom Kulen, a sandstone plateau known in Sanskrit inscriptions as Mahendraparvata, the mountain of the great Indra. There he was proclaimed chakravartin, universal ruler, and took the title devaraja, god-king, according to the Sdok Kak Thom inscription cited in UNESCO's tentative-list documentation for the site. World History Encyclopedia notes this 802 date is the one historians use to mark the empire's beginning, after Jayavarman II had spent years subjugating the patchwork of smaller Khmer kingdoms through military campaigns and alliances. Archaeological survey of the plateau has found around 40 brick temples, ancient reservoirs, dykes, channels, and platforms, evidence of a real settlement rather than a purely symbolic mountaintop.
Why it matters
The devaraja title became the ideological backbone of Khmer kingship for the next six centuries: every major temple that followed, including Angkor Wat and the Bayon, was built partly to embody a king's claim to be a living god's earthly presence. Historians still debate what "Java" meant in the inscriptions, whether it names the island of Java, a Cham kingdom, or something else, which is a reminder that even the empire's founding moment survives only through a later inscription, not a contemporary record.
How we know
The primary evidence is the Sdok Kak Thom inscription, carved more than two centuries after Jayavarman II's death, which explicitly links the 802 ceremony to the founding of the devaraja cult. Lidar and ground survey by the Cambodian Archaeology and Development Foundation, published by archaeologist Jean-Baptiste Chevance and colleagues, has since mapped the grid-planned city around the ceremonial site.
