Very slowly the truth about America was borne in upon the people of Europe. They persisted in calling the newly discovered lands the "Indies," and even after Balboa had discovered (1513) that another ocean lay beyond the Isthmus of Panama, it was thought that a few days' sail would bring one to the outlying possessions of the Great Khan. Not until Magellan, leaving Spain in 1519, passed through the straits that still bear his name and crossed the Pacific was this vain hope relinquished. Magellan was killed by the natives of the Philippine Islands, but one of his ships reached Seville in 1522 with the tale of the marvelous voyage. Even after the circumnavigation of the world explorers looked for channels leading through or around the Americas. Such were the attempts of Verrazano (1524), Cartier (1534), Frobisher (1576-1578), Davis (1585-1587), and Henry Hudson in 1609. ESTABLISHMENT OF COLONIAL EMPIRES [Sidenote: Portugal] When Vasco da Gama returned to Lisbon in 1499 with a cargo worth sixty times the cost of his expedition, the Portuguese knew that the wealth of the Indies was theirs. Cabral in 1500, and Albuquerque in 1503, followed the route of Da Gama, and thereafter Portuguese fleets rounded the Cape year by year to gain control of Goa (India), Ormuz, Diu (India), Ceylon, Malacca, and the Spice Islands, and to bring back from these places and from Sumatra, Java, Celebes, and Nanking (China) rich cargoes of "spicery." After the Turkish conquest of Egypt in 1517 the bulk of commerce was carried on by way of the Cape of Good Hope, for it was cheaper to transport goods by sea than to pay taxes to the Turks in addition to caravan cartage. Lisbon rapidly gained prominence as a market for Eastern wares. The Portuguese triumph was short-lived. Dominion over half the world-- for Portugal claimed all Africa, southern Asia, and Brazil as hers by right of discovery--had been acquired by the wise policy of the Portuguese royal house, but Portugal had neither products of her own to ship to Asia, nor the might to defend her exclusive right to the carrying trade with the Indies. The annexation of Portugal to Spain (1580) by Philip II precipitated disaster. The port of Lisbon was closed to the French, English, and Dutch, with whom Philip was at war, and much of the colonial empire of Portugal was conquered speedily by the Dutch. [Sidenote: Spain]
