Angkor's Vietnamese Campaigns and the Shifting Southeast Asian Balance

This episode of Fexingo History explores a little-known turning point in the decline of the Khmer Empire: the devastating Vietnamese campaigns of the 14th and 15th centuries. Hosts Lucas and Luna discuss how the Dai Viet under the Tran and Later Le dynasties exploited Khmer weakness, launching raids that destabilized the eastern frontier and diverted resources from the growing Tai threat. They examine the 1372 Cham-Khmer alliance against Dai Viet, the 1421 Vietnamese occupation of Vijaya, and the long-term demographic shifts that drained Angkor's population. The episode also considers how the Khmer script and Theravada Buddhism survived despite political collapse, and why modern Cambodian identity still carries the scars of these forgotten wars. Specific figures include King Ponhea Yat, Le Loi, and the Cham king Che Bong Nga.
