Diachronic modeling of the population within the medieval Greater Angkor Region settlement complex

9 pagesAngkor is one of the world’s largest premodern settlement complexes (9th to 15th centuries CE), but to date, no comprehensive demographic study has been completed, and key aspects of its population and demographic history remain unknown. Here, we combine lidar, archaeological excavation data, radiocarbon dates, and machine learning algorithms to create maps that model the development of the city and its population growth through time. We conclude that the Greater Angkor Region was home to approximately 700,000 to 900,000 inhabitants at its apogee in the 13th century CE. This granular, diachronic, paleodemographic model of the Angkor complex can be applied to any ancient civilization.We wish to thank the APSARA National Authority for permission to conduct remote sensing and collaborative field investigations.

Trajectories of Urbanism in the Angkorian World

International audienceThe Angkorian World explores the history of Southeast Asia's largest ancient state from the first to mid-second millennium CE. Chapters by leading scholars combine evidence from archaeology, texts, and the natural sciences to introduce the Angkorian state, describe its structure, and explain its persistence over more than six centuries. Comprehensive and accessible, this book will be an indispensable resource for anyone studying premodern Asia. The volume's first of six sections provides historical and environmental contexts and discusses data sources and the nature of knowledge production. The next three sections examine the anthropogenic landscapes of Angkor (agrarian, urban, and hydraulic), the state institutions that shaped the Angkorian state, and the economic foundations on which Angkor operated. Part V explores Angkorian ideologies and realities, from religion and nation to identity. The volume's last part reviews political and aesthetic Angkorian legacies in an effort to explain why the idea of Angkor remains central to its Cambodian descendants. Maps, graphics, and photographs guide readers through the content of each chapter. Chapters in this volume synthesise more than a century of work at Angkor and in the regions it influenced. The Angkorian World will satisfy students, researchers, academics, and the knowledgeable layperson who seeks to understand how this great Angkorian Empire arose and functioned in the premodern world
