Claude Markovits' book charts the development of two merchant communities in the province of Sind from the precolonial period, through colonial conquest and up to indepedence. Based on previously neglected archival sources, it describes how the communities came to control trading networks throughout the world, throwing light on the nature of these diasporas from South Asia in their interaction with the global economy. This is a sophisticated and accessible book that will appeal to students of South Asia, as well as to colonial historians and economic historians.
