This compilation of original research articles highlight the important cross-regional, cross-chronological, and comparative approaches to political and economic landscapes in ancient South Asia and its neighbors. Focusing on the Indus Valley period and Iron Age India, this volume incorporates new research in South Asia within the broader universe of archaeological scholarship. Contributions focus on four major themes: reinterpreting material culture; identifying domains and regional boundaries; articulating complexity; and modeling interregional interaction. These studies develop theoretical models that may be applicable researchers studying cultural complexity elsewhere in the world.
