Angkor's Final Collapse: The Climate-Economy Death Spiral

In this episode of The Khmer Empire's Sudden Collapse Explained, we explore the final decades of Angkor through a lens we haven't used before: the economic and ecological death spiral that followed the megadroughts of the 14th and 15th centuries. Lucas and Luna examine how the breakdown of the baray irrigation system led not just to water scarcity, but to a cascade of failures—crop loss, famine, erosion of the devaraja cult, and the rise of competing trade networks controlled by Ayutthaya. We focus on the lesser-known figure of King Ponhea Yat, who moved the capital to Phnom Penh in 1431 after the Siamese sack of Angkor Thom, and we discuss recent archaeological evidence from the site of Banteay Chhmar that suggests a slow, grinding abandonment rather than a sudden exodus. The episode also touches on the role of Theravada Buddhism's rise in undermining the divine authority of the Khmer kings, and how the loss of ritual control over water may have been the final blow. Specifics include: the role of the Tonle Sap's flood pulse, the collapse of the West Baray, the shift from Sanskrit to Pali inscriptions, and the pivot to maritime trade via the Mekong Delta. This is a story of interconnected systems—water, faith, power, and trade—falling apart in slow motion. #KhmerEmpire #AngkorCollapse #PonheaYat #Ayutthaya #Megadrought #BaraySystem #Devaraja #TheravadaBuddhism #TonleSap #PhnomPenh #BanteayChhmar #MekongDelta #ClimateHistory #Archaeology #SoutheastAsiaHistory #EconomicCollapse #History #FexingoHistory #AngkorWat #SuryavarmanII Keep every episode free: buymeacoffee.com/fexingo
