European traders would

European traders would export manufactured goods to the coast of Africa where they would be exchanged for slaves. Within the Portuguese Empire, most black African slaves were traded to Portuguese merchants who bought them to sell as cheap labour for use on Brazilian agricultural plantations. This trade would last until the first half of the 19th century.

The Portuguese gradually took control of the coastal strip during the 16th century by a series of treaties and wars forming the Portuguese colony of Angola. Taking advantage of the Portuguese Restoration War, the Dutch occupied Luanda from 1641 to 1648, where they allied with local peoples, consolidating their colonial rule against the remaining Portuguese resistance. In 1648, a fleet under the command of Salvador de Sá retook Luanda for Portugal and initiated a conquest of the lost territories, which restored Portugal to its former possessions by 1650. Treaties regulated relations with Kongo in 1649 and Njinga's Kingdom of Matamba and Ndongo in 1656. The conquest of Pungo Andongo in 1671 was the last great Portuguese expansion, as attempts to invade Kongo in 1670 and Matamba in 1681 failed. Portugal expanded its territory behind the colony of Benguela in the 18th century, and began the attempt to occupy other regions in the mid-19th century.
