Quick facts

Shift
Hindu-Mahayana kingship to Theravada Buddhism
Period
13th-14th century CE

What happened

Over the 13th and 14th centuries, Khmer religious practice shifted decisively away from the blend of Hinduism and Mahayana Buddhism that had underpinned centuries of devaraja kingship, toward Theravada Buddhism, a tradition emphasizing personal reflection, simplicity, and social equality. The National Library of Australia's account of the decline states this presented a direct challenge to the traditional class structure and divine authority of the kings, since Theravada teaching offered little support for the idea that a monarch was a living god. Tensions grew between Theravada's spiritual ideals and the rigid hierarchies of royal power that the devaraja cult and monumental temple-building had depended on. Columbia Magazine's reporting on Angkor scholarship notes that some researchers, including historian Victor Lieberman, argue Angkor's political structure disintegrated as Buddhism swept through the region in the 13th century, precisely because Angkor's rulers had built their authority on being earthly representations of Hindu gods.

Why it matters

A religious shift is not usually thought of as a cause of imperial collapse, but here it directly undercut the ideological basis for why kings could command the enormous labor forces needed to build and, crucially, maintain the barays and temples. Some historians connect the decline in that maintenance capacity to this same religious change, while others weigh it against economic and climate explanations instead.

How we know

The shift is tracked through the archaeological and inscriptional record: dedications to Hindu deities and the devaraja cult grow rare in later centuries while Theravada Buddhist imagery becomes more common, though the exact pace and causes of the religious change remain debated among scholars, some of whom favor economic or climate explanations over a purely religious one.
