Overview

"Portuguese Africa" denotes the African possessions of the Portuguese Empire—the first and longest-lived European colonial empire (1415–1999)—including the Moroccan coastal strongholds, Arguin, Guinea and the Gold Coast (Elmina), Kongo and Angola, Mozambique, and the islands of Cape Verde and São Tomé and Príncipe. The table's window, 1507–1581, captures the height of the first "trading-post empire," when Portugal's African holdings were still a thin chain of forts (feitorias) rather than territorial colonies.

History

The African venture began with the conquest of Ceuta in Morocco in 1415 and Henry the Navigator's sponsorship of exploration down the Atlantic coast: Madeira (1419), the Azores (1427), Cape Bojador (1434), Senegal (1445), and the Gulf of Guinea by the 1460s. Fernão Gomes's traders found alluvial gold at Mina, secured after the naval victory over Castile at the Battle of Guinea (1478); João II built the great castle of São Jorge da Mina (Elmina) in 1482. Diogo Cão reached the Congo River in 1482–83, opening the remarkable alliance with the Christianizing Kingdom of Kongo, and Bartolomeu Dias rounded the Cape in 1488, enabling Vasco da Gama's voyage to India (1498).

Through the 16th century the African posts underpinned the empire's economy: Guinea gold, ivory, pepper—and above all slaves, of whom Portugal shipped around 800 a year for over a century, making black Africans perhaps 10% of Lisbon's population and feeding the sugar plantations of Madeira and São Tomé. On the east coast, Kilwa and Mombasa were taken in 1505 and Mozambique Island fortified as the way-station to Goa. In the interior, prazeros held vast estates along the Zambezi and meddled in the Mutapa kingdom. Portugal intervened militarily in Ethiopia against Adal (1541–43) and founded Luanda in Angola in 1576, which became the Atlantic's greatest slave port.

Decline and legacy

The empire's African overextension collapsed after King Sebastian's death at Alcácer Quibir in Morocco (1578); the Iberian Union with Spain (1580) exposed Portuguese Africa to Dutch, English and French attack, beginning a long contraction that by 1769 cost it even its Moroccan enclaves. Territorial empire in Angola and Mozambique came only in the 19th century and ended in the bloody Colonial War (1961–74) and decolonization after the Carnation Revolution. The legacy endures in the five Lusophone African nations and the CPLP.
