As the Portuguese crept cautiously along the western coast of Africa, they met a dizzying multiplicity of African cultures but nowhere did they encounter an economic vacuum. Since their primary interest was trade (pious disclaimers to the contrary), they had to discover and then adapt to local and interregional patterns of exchange before they could hope to exploit them to their advantage.
The two centuries between the discovery of Capo Blanco and adjacent Arguim Island in 1443 and the fall of Elmina to the Dutch in 1640 circumscribe the period of Portuguese hegemony and the opening phase of European-African interaction. Though other Europeans followed close on their heels, it was the Portuguese who pioneered both physically and commercially. Ships might put in almost anywhere along the coast where they could find a safe anchorage, but there were five regions that from the beginning seemed to promise profitable and convenient trading contacts: Arguim, Senegambia and the “Rivers of the South,” the Gold Coast, Benin and the Slave Rivers, and Congo-Angola. Each of these presented a different situation and each demanded a different response.
These regions have been the subject of specialized monographs which have brought out the local characteristics of trade as they evolved, but there has been no attempt at an overview, no attempt to compare and generalize from the data now available to present a larger picture of trading patterns on the West Coast of Africa as a whole.
