In the past quarter century, Champa scholarship has been seeking ways out of the interpretative framework inherited from Georges Maspero’s Le royaume de Champa, which portrayed Champa as a unitary kingdom of provinces ruled by “absolute” kings. Scholars have since been working to revise this portrait, to develop new thinking about the way the kingdom and its territories were structured, and also to critique Maspero’s decision to end his history of Champa with the 1471 capture of the Chà Bàn citadel and fall of Vijaya. Much new data has been produced in recent decades, thanks especially to the access to Champa field sites enjoyed since the 1990s by international scholars under Vietnam’s open door policy, and to the resources for research and discussion now available to Vietnamese scholars. Several long-term joint projects have, moreover, brought Vietnamese and overseas expertise to bear on archaeological sites or collections of documents related to Champa. The production of knowledge about Champa is thus thriving. The result is an incremental, multi-disciplinary mosaic of information on Champa’s past. Some of this scholarship was published in two recent volumes: Champa and the Archaeology of Mỹ Sơn (Hardy et al. 2009) and The Cham of Vietnam (Trần Kỳ Phương & Lockhart 2011). The present volume stands in the same tradition, as a book of ground-breaking data that contributes to the renewal of Cham-pa studies. As these data are gradually sorted, new patterns that transform our understanding of Champa are becoming discernible. One of the most striking pertains to maps. This book offers a new framework for general discussion of Champa’s space, and several new maps that amount to a template for cartographical representations of the kingdom and its territories at specific historical moments. Another contribution of this volume is the publication of new data that yield ground-breaking insights into the nature of Champa’s presence in the highlands. Part I of the book focuses on the territories that constituted Champa, making use of data from recent excavations, archaeological and ethnographic surveys, inscriptions, and Cham-language manuscripts from the post-1471 period. In Part II, we turn to Champa as a kingdom, using data from epigraphy and Vietnamese chronicles, but also from architectural-archaeological study of a royal temple foundation at Mỹ Sơn. Three authors present new data and analysis of the Champa kingdom in the 15th century, grappling with the issue of the kingdom’s tendency toward fragmentation and eventual decline. Part III focusses on the regional connectedness of Champa. These include diplomatic and cultural ex-changes with China and India, artistic and trading relations with mainland Southeast Asian countries, and language links with the Malay World.
