Ouidah, an African town in the Republic of Benin, was the principal precolonial commercial center of its region and the second-most-important town of the Dahomey kingdom. It served as a major outlet for the transatlantic slave trade. Between the seventeenth and the nineteenth centuries, Ouidah was the most important embarkation point for slaves in the region of West Africa known to outsiders as the Slave Coast. This is the first detailed study of the town's history and of its role in the Atlantic slave trade.

Ouidah is a well-documented case study of precolonial urbanism, of the evolution of a merchant community, and in particular of the growth of a group of private traders whose relations with the Dahomian monarchy grew increasingly problematic over time.
