Global Exploration (14.1)

Chapter 14 Section 1


Throughout history, groups of people—from the ancient Greeks to Muslim Arabs and the Vikings of Scandinavia—had explored the seas, trading and migrating over long distances. The European sailors of the 1400s began a dramatic new period of exploration.

Motivations for Exploring the Seas


Europeans traded with Asians long before the Renaissance. The Crusades introduced Europeans to many luxury goods from Asia, carried on complex overland routes through the Mongol empire of the 1200s and 1300s. The Black Death and the breakup of the Mongol empire disrupted that trade. By the 1400s, though, Europe’s population was growing, along with its demand for trade goods. The most valued items were spices, used to preserve food, add flavor to meat, and make medicines and perfumes. The chief source of spices was the Moluccas, an island chain in present-day Indonesia, which Europeans then called the Spice Islands.

In the 1400s, Arab and Italian merchants controlled most trade between Asia and Europe. Muslim traders brought prized goods to eastern Mediterranean ports, and Italian traders carried them to European markets. Europeans outside Italy knew that it would be more profitable to gain direct access to Asia. They were also driven by Renaissance curiosity to seek new lands.

Portugal Sails East


Prince Henry led the way in sponsoring exploration for Portugal, a small nation next to Spain. First, Prince Henry’s navigators discovered and claimed the Madeira and Azores islands to the west and southwest of Portugal. By 1415, Portugal had expanded into Muslim North Africa, seizing the port of Ceuta (syoo tah) on the North African coast.

Mapping the African Coast

Prince Henry saw great promise in Africa. The Portuguese could convert the Africans—who practiced either Islam or tribal religions—to Christianity. He also believed that in Africa he would find the sources of riches the Muslim traders controlled.

Finally, Prince Henry hoped to find an easier way to reach Asia, which meant going around Africa. The Portuguese felt that with their expert knowledge and technology, they could accomplish this feat. At Sagres, in southern Portugal, Henry gathered scientists, cartographers, or mapmakers, and other experts. They redesigned ships, prepared maps, and trained captains and crews for long voyages. Henry’s ships then slowly worked their way south to explore the western coast of Africa.

Henry died in 1460, but the Portuguese continued their quest. In 1488, Bartholomeu Dias rounded the southern tip of Africa. Despite the turbulent seas around it, the tip became known as the Cape of Good Hope because it opened the way for a sea route to Asia.

Seeking India

In 1497, Portuguese navigator Vasco da Gama followed in Dias’s footsteps, leading four ships around the Cape of Good Hope. Da Gama, however, had plans to go farther. After a ten-month voyage, da Gama reached the great spice port of Calicut on the west coast of India. On the long voyage home, the Portuguese lost half their ships, and many sailors died of hunger, thirst, and scurvy, a disease caused by a lack of vitamin C in the diet.


Despite the hard journey, the venture proved highly profitable. In India, da Gama had acquired a cargo of spices that he sold at an enormous profit. He quickly outfitted a new fleet, seeking greater profits. In 1502, he forced a treaty on the ruler of Calicut. Da Gama then left Portuguese merchants there whose job was to buy spices when prices were low and store them until the next fleet could return. Soon, the Portuguese had seized key ports around the Indian Ocean, creating a vast trading empire. Da Gama’s voyages confirmed Portugal’s status as a world power.

Columbus Sails West


News of Portugal’s successes spurred other people to look for a sea route to Asia. An Italian navigator from Genoa, named Christopher Columbus, wanted to reach the East Indies—a group of islands in Southeast Asia, today part of Indonesia—by sailing west across the Atlantic. Like most educated Europeans, Columbus knew that Earth was a sphere. A few weeks sailing west, he reasoned, would bring a ship to eastern Asia. His plan made sense, but Columbus greatly underestimated Earth’s size. And he had no idea that two continents lay in his path.


Reaching Faraway Lands

Portugal refused to sponsor him, but Columbus persuaded Ferdinand and Isabella of Spain to finance his voyage. To increase their authority, the Spanish rulers had taken radical measures, including expelling Jews from Spain. They hoped their actions would strengthen Catholicism. However, the loss of some of Spain’s most affluent and cultured people weakened the nation. The rulers hoped Columbus’s voyage would bring wealth and prestige.

Columbus spent several months cruising the islands of the Caribbean. Because he thought he had reached the Indies, he called the people of the region “Indians.” In 1493, he returned to Spain to a hero’s welcome. In three later voyages, Columbus remained convinced that he had reached the coast of East Asia. Before long, though, other Europeans realized that Columbus had found a route to previously unknown continents.

Dividing the Globe in Half

In 1493 Ferdinand and Isabella appealed to the Spanish-born Pope Alexander VI to support their claim to the lands of the new world. The pope set a Line of Demarcation, dividing the non-European world into two zones. Spain had trading and exploration rights in any lands west of the line. Portugal had the same rights east of the line. The specific terms of the Line of Demarcation were agreed to in the Treaty of Tordesillas, signed between the two countries in 1494. The actual line was unclear, because geography at the time was imprecise. However, the treaty made it obvious to both Spain and Portugal—and to other European nations, eager to defy what they saw as Spain and Portugal’s arrogance—that they needed to build their own empires quickly.

Naming the Western Hemisphere

An Italian sea captain named Amerigo Vespucci wrote a journal describing his voyage to Brazil. In 1507, a German cartographer named Martin Waldseemüller used Vespucci’s descriptions of his voyage to publish a map of the region, which he labeled “America.” Over time, the term “Americas” came to be used for both continents of the Western Hemisphere. The islands Columbus had explored in the Caribbean became known as the West Indies.

The Search for a Direct Route Continues


Though Europeans had claimed vast new territories, they had not yet found a direct route to Asia. The English, Dutch, and French explored the coast of North America unsuccessfully for a “northwest passage,” or a route from the Atlantic Ocean to the Pacific through the Arctic islands. Meanwhile, in 1513 the Spanish adventurer Vasco Núñez de Balboa, helped by local Indians, hacked a passage westward through the tropical forests of Panama. From a ridge on the west coast, he gazed at a huge body of water. The body of water that he named the South Sea was in fact the Pacific Ocean.

On September 20, 1519, a minor Portuguese nobleman named Ferdinand Magellan set out from Spain with five ships to find a way to reach the Pacific. Magellan’s ships sailed south and west, through storms and calms and tropical heat. At last, his fleet reached the coast of South America. Carefully, they explored each bay, hoping to find one that would lead to the Pacific. In November 1520, Magellan’s ships entered a bay at the southern tip of South America. Amid brutal storms, rushing tides, and unpredictable winds, Magellan found a passage that later became known as the Strait of Magellan. The ships emerged into Balboa’s South Sea. Magellan renamed the sea the Pacific, from the Latin word meaning peaceful.

Their mission accomplished, most of the crew wanted to return to Spain the way they had come. Magellan, however, insisted that they push on across the Pacific to the East Indies. Magellan underestimated the size of the Pacific. Three more weeks, he thought, would bring them to the Spice Islands. Magellan was wrong. For nearly four months, the ships plowed across the uncharted ocean. Finally, in March 1521, the fleet reached the Philippines, where Magellan was killed. On September 8, 1522, nearly three years after setting out, the survivors—one ship and 18 sailors—reached Spain. The survivors had been the first people to circumnavigate, or sail around, the world. Antonio Pigafetta, one of the few survivors of the expedition, observed: “I believe of a certainty that no one will ever again make such a voyage.”
