What explains the spread of Theravada Buddhism? And how is it entangled with the identity shifts that over the next four hundred years gave rise to the Buddhist state now called Cambodia? Early Theravadin Cambodia sheds light on one of the outstanding questions of Southeast Asian history: the nature and timing of major cultural and political shifts in the territory that was to become Cambodia, starting in the 13th century. This important collection challenges the conventional picture of Theravada as taking root in the void left by the collapse of Angkor and its Hindu-Buddhist power structure. Written by a diverse group of scholars from Cambodia, Thailand, the United States, France, Australia, and Japan, this volume is a sustained, collaborative discussion of evidence from art and archaeology, and how it relates to questions of Buddhist history, regional exchange networks, and ethnopolitical identities. Accessibly written and vividly illustrated, the book will be a crucial reference for historians of Southeast Asia and scholars of Buddhism.
