Despite the growth of studies on slavery and slave trade outside the Atlantic world in recent years, especially in the early modern Indian Ocean and Indonesian Archipelago worlds, our knowledge of regional price levels and their development remains surprisingly underdeveloped. This article questions how the price of enslaved people developed in the multi-directional and multi-faceted Indian Ocean and Indonesian Archipelago slave trade, how this compared to the Atlantic world and what this tells us about slave trade and slavery in different parts of the world. Drawing on evidence from a large variety of sources, mainly from the Dutch Indian Ocean and Indonesian Archipelago world, this article expands the body of data significantly and provides for the first time a reconstruction of the level of slave trade prices and their development in several important supplying and demanding slave trade regions in the Indian Ocean and Indonesian Archipelago world and compares these to the development of slave prices in the Atlantic slave trade.
