Abstract: In the eighteenth and nineteenth centuries, Angola was the principal source of slaves for the Americas. A large number of these captives embarked from the Portuguese ports of Luanda and Benguela, the details of which have been well documented by historians. However, many more embarked from African controlled ports situated north of Luanda, such as Ambriz, Cabinda, Molembo, and the Congo River. The size, proportion, and variation in the number of slaves embarked from these ports has been somewhat elusive, but Voyages: The Trans-Atlantic Slave Trade Database rectifies this by providing detailed records of vessels that carried slaves from the ports north of Luanda. This article used these records to generate the first port-by-port estimate of slaves embarked from Angola from the eighteenth to the nineteenth century.
