The Water Crisis That Helped Bring Down Angkor

Angkor Wat is the world's largest religious monument, but the Khmer Empire that built it collapsed around the same time as the cathedral-building era in Europe. This episode digs into a less-known factor in the empire's decline: its water management system. The Khmer kings engineered an enormous network of canals, reservoirs called barays, and embankments to control the monsoon floods and sustain rice agriculture for a population of nearly a million. But by the 14th century, climate change—prolonged droughts followed by intense monsoon rains—pushed that system past its limits. Sedimentation choked the canals, the barays silted up, and the elaborate waterworks became more of a liability than an asset. We look at the evidence from tree-ring studies and sediment cores from the Tonlé Sap lake, and how the shift to Theravada Buddhism and the rise of Ayutthaya accelerated the move of the capital south to the riverine trade routes near modern Phnom Penh. The stone temples survived; the hydraulic state did not. #Angkor #KhmerEmpire #WaterManagement #Baray #TonleSap #AngkorWat #ClimateChange #Drought #SoutheastAsianHistory #HydraulicEngineering #TheravadaBuddhism #Ayutthaya #Sedimentation #TreeRingDating #GreaterAngkorProject #Collapse #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo
