15th century – 18th century
West, North, Central and East Africa
Portuguese expansion in Africa was a long process of maritime trade, fortified coastal occupation, military intervention, and control over commercial routes. Beginning with trading posts on the West African coast, Portugal extended its influence through Morocco, the Gold Coast, the Congo, Angola, and parts of East Africa. Its objectives included access to gold, ivory, metals, and enslaved people, while African rulers and traders remained indispensable intermediaries. Portuguese power later weakened under financial pressure and European competition.

The Story
Portuguese expansion in Africa developed through a combination of maritime enterprise, fortified trading posts, and selective military conquest. During the fifteenth and early sixteenth centuries, Portuguese agents established numerous posts on the West African coast and drew coastal populations and rulers into commercial exchanges. In North Africa, the Portuguese competed with Spain, France, Muslim polities, and the Ottoman Empire, while in sub-Saharan Africa they sought access to gold and established routes linking the coast with inland markets.
The Portuguese employed different methods in different regions. On the Gold Coast, El Mina became a major commercial centre after 1481–1482, while in East Africa Portuguese forces attacked Sofala, Mombasa, and other coastal towns, installed garrisons, and imposed taxes in the name of the king of Portugal. Their ambitions extended beyond the coast: they attempted to control the movement of gold, ivory, and metals between African hinterlands, the Indian Ocean, and India.
Portuguese power also expanded through the search for enslaved labour. Commercial involvement in Senegambia provided methods that were later applied elsewhere, and cooperation with local rulers and traders became central to Portuguese activity. This search for large supplies of enslaved people contributed to Portuguese penetration into the Congo during the early sixteenth century and to the later conquest of Angola, while the island of São Tomé became a centre supplying labour for plantations and overseas markets.
The system placed heavy financial demands on Portugal. Gold and enslaved people had to be purchased with imported goods, while fleet construction depended on timber from the Baltic region and other supplies came through European trading centres. Portuguese rulers therefore relied on major financiers from Italy and Germany. Military costs, rising prices, competition, and the expense of colonial administration weakened the crown, whose first bankruptcy occurred in 1560. Portuguese influence subsequently deteriorated in Morocco and faced increasingly strong French, English, and Dutch rivals.
