For centuries Portugal was a small and poor nation on the margins of European life. Yet Portugal had a long history of seafaring and navigation. Blocked from access to western Europe by Spain, the Portuguese turned to the Atlantic. Nature favored the Portuguese: winds blowing along their coast offered passage to Africa, its Atlantic islands, and, ultimately, Brazil.

In the early phases of Portuguese exploration, Prince Henry (1394–1460), a dynamic younger son of the king, played a leading role. A nineteenth-century scholar dubbed Henry “the Navigator” because of his support for the study of geography and navigation and for the annual expeditions he sponsored down the western coast of Africa.

Portugal’s conquest of Ceuta, an Arab city in northern Morocco, in 1415 marked the beginning of European overseas expansion. In the 1420s, under Henry’s direction, the Portuguese began to settle the Atlantic islands of Madeira (ca. 1420) and the Azores (1427). In 1443 they founded their first African commercial settlement at Arguin in North Africa. By the time of Henry’s death in 1460, his support for exploration had resulted in thriving sugar plantations on the Atlantic islands, the first arrival of enslaved Africans in Portugal (see “Sugar and Early Transatlantic Slavery”), and new access to African gold.

The Portuguese next established fortified trading posts, called factories, on the gold-rich Guinea coast and penetrated into the African continent all the way to Timbuktu (Map 16.2). By 1500 Portugal controlled the flow of African gold to Europe. In contrast to the Spanish conquest of the Americas (see “Spanish Conquest of the Aztec and Inca Empires”), the Portuguese did not establish large settlements in West Africa or seek to control the political or cultural lives of those with whom they traded. Instead they sought to profit by inserting themselves into pre-existing trading systems.

In 1487 Bartholomew Diaz (ca. 1451–1500) rounded the Cape of Good Hope at the southern tip of Africa (Map 16.2), but storms and a threatened mutiny forced him to turn back. A decade later Vasco da Gama (ca. 1469–1524) succeeded in rounding the Cape while commanding a fleet in search of a sea route to India. With the help of an Indian guide, da Gama reached the port of Calicut in India. He returned to Lisbon with spices and samples of Indian cloth, having proved the possibility of lucrative trade with the East via the Cape route. Thereafter, a Portuguese convoy set out for passage around the Cape every March.

Lisbon became the entrance port for Asian goods into Europe, but this was not accomplished without a fight. Muslim-controlled port city-states had long controlled the rich trade of the Indian Ocean, and they did not surrender it willingly. From 1500 to 1515 the Portuguese used a combination of bombardment and diplomatic treaties to establish trading factories at Goa, Malacca, Calicut, and Hormuz, thereby laying the foundation for a Portuguese trading empire in the sixteenth and seventeenth centuries. The acquisition of port cities and their trade routes brought riches to Portugal, but, as in Africa, the Portuguese had limited impact on the lives and religious faith of peoples beyond Portuguese coastal holdings.

Inspired by the Portuguese, Spain had also begun the quest for empire. Theirs was to be a second, entirely different mode of colonization leading to large-scale settlement and the forced assimilation of huge indigenous populations.
