This book contains an analysis of the rise of the settlement system in the heartland of the Minangkabau region in the highlands of West Sumatra, Indonesia. The essays explore the regional settlement pattern arising from Adityavarman's highland interregnum and attempt to place the archaeological remains and the landscape of Tanah Datar in a cultural historic synthesis. The book consists of studies of metal, ceramics and glass finds by laboratory-based specialists and descriptions of stone, clay and other finds.
