The Water Crisis That Drowned Angkor: Drought and the Khmer Collapse
Description
Lucas and Luna explore the role of climate and water management in the fall of the Khmer Empire. While previous episodes focused on invasions, religious shifts, and trade, this episode dives into the environmental catastrophe that may have been the final blow. Drawing on tree-ring data from Vietnam and Cambodia, the hosts discuss the decades-long drought in the 1300s and 1400s, followed by extreme monsoon floods that overwhelmed Angkor's massive hydraulic network of barays and canals. They examine how the devaraja's divine legitimacy depended on controlling water, and how the failure of that system eroded trust in the king. The episode also touches on the engineering marvels of the West Baray and the East Baray, and the recent lidar discoveries of water channels. Lucas notes that the shift to Theravada Buddhism offered a more personal salvation that appealed to a populace abandoned by a failed state. The conversation ends with a reflection on how environmental factors, often overlooked, may have been as decisive as any army.
