Central Africa became deeply intertwined in the Atlantic world with the arrival of the Portuguese in 1482, which opened up a new world of connections between African societies and European and American partners. As a region, central Africa stretches from Gabon to Mossamedes, near the border of the present nation of Namibia. Two distinct patterns of interaction marked the region’s integration into the wider Atlantic world. On the Loango coast, Atlantic trade by Dutch, British, and French merchants favored African kings in the short term but eventually paved the way for the rise of coastal rulers who seized upon wealth amassed through the slave trade to challenge kingship. After first playing out in the kingdom of Kongo, this dynamic unfolded in several other polities, such as the kingdom of Ngoyo and Ndongo.
South of the Congo River, Portugal’s ability to carve out coastal enclaves in Luanda and Benguela powerfully shaped the relationship with the Atlantic world. Both cities developed sprawling trading networks with their immediate hinterlands as well as several cities across the Atlantic, particularly in Brazil but later also in Cuba. Although the slave trade formed the cornerstone of trading networks, a continuum of social, cultural, and political ties bridged the ocean. Portuguese institutional and economic presence was deeply dependent on Angola’s ties with Brazil. The two Portuguese colonies interacted bilaterally, and Brazil was not only the source of commodities for the trade in human beings but also in crops, food supplies, and military hardware.
Distinct patterns of Afro-European interaction in Loango and Portuguese Angola should not hide the intense trade between these two regions. Since the 17th century, Luanda had depended on the Loango coast for palm-cloth currencies (libongos) that circulated widely in the capital city of Portuguese Angola. Cabinda men sailed to Luanda to purchase tobacco and sell slaves and other goods. As the French and then the British abandoned the slave trade, the direct slave trade with Brazil intensified and altered the structure of shipments of captives. In addition to the tightening Brazilian grip over central Africa’s slave trade, this development further integrated coastal trade between Loango and Portuguese Angola and set the stage for the continuation of shipments of captives until the 1860s.
