## Resource

In this episode, Lucas and Luna explore a fresh theory about the Khmer Empire's collapse: not war, not drought alone, but a cascading infrastructure failure tied to Angkor's massive moat system. Drawing on recent LiDAR data and sediment core studies, they discuss how the moats around Angkor Thom and Angkor Wat — once symbols of divine power and hydraulic control — may have become vectors for disease and political fragmentation when monsoon patterns shifted in the 14th century. The episode examines the role of the baray system, the breakdown of the devaraja cult, and a pivotal 1380s inscription from the Preah Khan temple that hints at a climate-driven crisis. Lucas also tells the story of a forgotten Khmer engineer, Virak Srei, whose name appears in a single stela (K. 1051) as the last recorded superintendent of Angkor's canals — a figure who may have witnessed the system's final failure. #KhmerEmpire #AngkorMoat #AngkorThom #AngkorWat #devaraja #baray #LiDAR #PreahKhan #VirakSrei #K1051 #ClimateChange #HydraulicCollapse #SoutheastAsia #Archaeology #Cambodia #14thCentury #Infrastructure #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo
