AMSCO 4.2 Exploration: Causes and Events Notes

Overview

AMSCO Topic 4.2, "Exploration: Causes and Events" (AMSCO p. 199-208), explains why European states started paying for risky ocean voyages between 1450 and 1750 and what those voyages produced. The short version: Italian port cities held a monopoly on Mediterranean trade with Asia and controlled prices, so Spain and Portugal (and later France, England, and the Netherlands) went hunting for new routes. Add in gold fever, religious zeal to spread Christianity, and the new maritime technology from Topic 4.1, and you get the launch of state-sponsored transoceanic exploration that defines this unit.

Why States Sponsored Maritime Exploration

States, not lone adventurers, drove exploration because only governments could afford it. Voyages like Columbus's 1492 Atlantic crossing (backed by Queen Isabella and King Ferdinand of Spain) were too expensive for individual explorers or even most merchants.

States had four overlapping motives:

• Wealth and resources. Conquest brought new taxes, new trading opportunities, and eventually massive amounts of silver.
• Rivalry. European powers raced to claim territory before a competitor could grab it first.
• Religion. Many Europeans saw it as their Christian duty to find and convert people in other lands, and since religion was tightly woven into government, spreading the state's faith became state business.
• Mercantilism. By the 17th century, Europeans measured a country's wealth by its stockpile of gold and silver. So governments pushed policies to sell as much as possible to other countries (precious metals flow in) and buy as little as possible (precious metals stay put). That theory, mercantilism, required heavy government involvement in trade.

Columbus's voyages mattered beyond Spain. They sparked English, French, and Dutch interest in sponsoring exploration of their own.

Portugal Leads the Way

Portugal led European exploration just as it had led maritime innovation. The kingdom was small and boxed in by the Spanish kingdoms of Castile and Aragon, so the only direction it could expand was overseas. The interests of the state and the interests of explorers were tied together more closely here than anywhere else.

Three explorers to know

• Prince Henry the Navigator (1394-1460) became the first European monarch to sponsor seafaring expeditions, searching for an all-water route east and for African gold. Under Henry, Portugal began importing enslaved Africans by sea, replacing the overland slave trade.
• Bartholomew Diaz rounded the Cape of Good Hope at the southern tip of Africa in 1488, then turned back because he feared a mutiny.
• Vasco da Gama pushed farther, reaching India in 1498 and claiming territory for Portugal. Portuguese ports in India became the launching pad for trade across the Indian Ocean and beyond.

Into Southeast and East Asia

Early in the 16th century, the ruthless admiral Afonso de Albuquerque defeated Arab traders in a short, bloody battle and set up a factory at Malacca on the Malay Peninsula. He had previously governed Portuguese India (1509-1515) and was infamous for sending strings of Indians' ears back to Portugal as proof of his conquests.

China had ended its own exploration after Zheng He's final voyage in the 1430s. In 1514, the outside world showed up anyway: Portuguese traders, whose ships and weapons were unmatched in Europe. Portugal had already taken control of the African and Indian coasts and crushed a Turkish-Egyptian-Venetian fleet at Diu, India, in 1509.

Traders were followed by Catholic missionaries. Franciscans and Dominicans worked among ordinary Chinese, while Jesuits like Matteo Ricci (Italian, arrived 1582) and Adam Schall von Bell (German, arrived 1619) targeted the court elite from Macau, impressing them with scientific knowledge. It mostly didn't work. The hostile scholar-gentry considered the missionaries barbaric, and few converted.

The trading post empire

Instead of conquering large territories, Portugal built a chain of fortified outposts: Hormuz on the Persian Gulf (1507), Goa in western India (1510), and Malacca on the Malay Peninsula (1511). The goal was a monopoly on the spice trade. Portugal licensed all vessels trading between Malacca and Hormuz and restricted Indian Ocean trade to merchants who bought permits. This network of small forts, not big colonies, is what the AP exam means by a trading post empire.

Why Portugal couldn't hold on

Portugal succeeded for decades but was too small to enforce a global empire. It lacked the workers and ships, many Portuguese merchants ignored the government and traded independently, and official corruption ate away at the system. By the 17th century, Dutch and English rivals were moving in. The Dutch captured Malacca and built a fort at Batavia in Java in 1620, trying to monopolize the spice trade from there. The English focused on India and pushed the Portuguese out of South Asia. In Japan, Portuguese traders and missionaries (arriving 1549) built large Catholic settlements until the 1600s, when Japanese rulers outlawed Catholicism and expelled the missionaries.

Spain, Magellan, and the Pacific Silver Trade

Spanish ships were the first to circumnavigate the globe. The government sponsored Ferdinand Magellan's voyage; Magellan himself died in the Philippine Islands, but one ship from his fleet made it all the way around, proving the earth could be circumnavigated.

Spain annexed the Philippines in 1521 when Magellan's fleet arrived, returned in 1565, and fought a long campaign against fierce Filipino resistance. Manila became Spain's commercial center in the region, attracting Chinese merchants, and many Filipinos became Christians under Spanish and Portuguese occupation.

The lure of riches in the Americas

The Spanish found so little of value in their first two decades in the Americas that they considered quitting exploration entirely. What changed everything was contact with the Aztecs in Mesoamerica and the Incas in South America. These empires held the gold and silver that made conquest profitable. Europeans also realized they could grow rich raising sugar, tobacco, and other cash crops using enslaved Native Americans and, later, enslaved Africans.

Manila galleons and global silver

Silver from Mexico crossed the Pacific in heavily armed Spanish ships called galleons, stopping in the Philippines. At Manila, Europeans traded silver for silk, spices, and even gold bullion. China was an especially enthusiastic consumer; its government began using silver as its main currency. By the early 17th century, silver was a dominant force in the global economy. This trans-Pacific link is a favorite exam example of how exploration connected the whole world.

The Northern Europeans and the Northwest Passage

France, England, and the Netherlands all sponsored Atlantic crossings, often hunting for a northwest passage, a route through or around North America to Asia and its spice trade. Nobody found one, but the searching produced colonies.

French exploration

In 1535, Jacques Cartier sailed into the St. Lawrence River and claimed part of what is now Canada for France. Samuel de Champlain (explored 1609-1616) and others realized the Americas themselves held valuable resources, especially furs. The French founded Quebec as a town and trading post in 1608. In the 1680s, the trader La Salle explored the Great Lakes and followed the Mississippi River to the Gulf of Mexico, claiming the whole region for France.

The French rarely settled permanently. Instead of demanding land, they traded for furs trapped by Native Americans, which gave them better relations with indigenous peoples than the Spanish or English had. The tradeoff was slow growth: by 1754, New France had only 70,000 Europeans, while the English colonies had one million.

English exploration

In 1497, the English king sent John Cabot to look for a northwest passage; he claimed land from Newfoundland south to the Chesapeake Bay. England then sat out serious colonization for nearly a century because it couldn't match Spanish sea power (though English pirates called "sea dogs" raided Spanish ships). The turning point came in 1588, when England defeated the Spanish Armada, destroying all but one third of it. England then competed seriously for American land. In 1607, about one hundred colonists built Jamestown on the James River in Virginia, both named for King James I. It was England's first successful American colony, though the first colonies in the present-day United States were actually Spanish settlements in Florida and New Mexico.

Dutch exploration

In 1609, the Dutch sent Henry Hudson up the river now bearing his name, hoping it led to Asia. It didn't, but the voyage let the Dutch claim the Hudson River Valley and Manhattan, where they founded New Amsterdam (today's New York City). The port thrived as a node in Dutch transatlantic trade: furs from northern trappers and Virginia tobacco flowed to the Netherlands in exchange for manufactured goods sold throughout colonial North America.
