## Resource

When you think of Angkor's collapse, you probably think of drought, invasion, or religious upheaval. But what if the key was one massive engineering failure that cascaded into catastrophe? In this episode, Lucas and Luna investigate the mysterious West Baray — a 16-square-kilometer reservoir that stopped working in the 14th century, at the worst possible moment. They trace the baray's construction under Suryavarman II, its role in irrigating Angkor's rice fields and stabilizing the water table, and the evidence from lidar scans and tree-ring studies that shows how siltation and channel shifts turned a life-giving reservoir into a death sentence. They also explore the little-known figure of King Jayavarman VIII, whose Hindu reaction after Jayavarman VII's Buddhist revolution may have accelerated the neglect of the baray system. By the end, you'll see that Angkor's water crisis wasn't just about too little rain — it was about a system too brittle to survive its own success. #WestBaray #Angkor #KhmerEmpire #JayavarmanVIII #SuryavarmanII #WaterManagement #LidarArchaeology #MegaDrought #Siltation #TonleSap #AngkorWat #TheravadaBuddhism #Devaraja #GreaterAngkorProject #Hydraulics #Collapse #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo
