The Indian Ocean world has a rich history of socio-economic and cultural exchanges across time and space. This book and its companion, Merchants and Ports in the Indian Ocean World, explore these connections around the wider Indian Ocean world. The book examines the many overlapping linkages that existed from the early modern period and into the colonial era. It offers a clear understanding of the economic networks that extended across the Indian Ocean and the Atlantic during the 19th century. With a critical historical lens, the volume discusses themes like the opium trade in the Malay-Indonesian Archipelago – the biggest opium trade market at the time; the Safavid mission to Siam; and the economic relationship between Pondicherry and West Africa, via France. Rich in archival material, this book will be of interest for scholars and researchers of Indian Ocean history, maritime history, Indian history, economic and commercial history, South Asian history, and social history, anthropology, and trade relations in general.
