CAUSES of EUROPEAN EXPLORATION [AP World History Review—Unit 4 Topic 2]

Causes of European Exploration, 1450–1750

Why European states sponsored ocean exploration

Exploration was largely state-driven. After recovering from the Black Death, Europe’s population grew, and monarchs consolidated power at the expense of nobles. Stronger states built up their militaries, adopted gunpowder weapons, and improved taxation to fund costly voyages.

The search for spices was a powerful economic incentive. Europeans especially wanted Asian and Southeast Asian spices such as pepper. Because powerful empires controlled the land routes to these goods, spices were expensive in Europe, encouraging Europeans to seek sea routes.

Maritime technology also made longer voyages more practical. Europeans adopted tools such as the compass and astrolabe and developed ships suited to exploration, including the caravel and carrack.

Portugal: the first major maritime empire

Portugal’s position on the Iberian Peninsula limited its opportunities for land-based expansion, so it turned toward the sea. Prince Henry the Navigator sponsored early efforts to find a sea route to the Indian Ocean.

Portuguese exploration was driven by several motives:

• Technology: Portugal used navigational tools and ships suited to long voyages.
• Economic gain: Portuguese leaders sought gold from trans-Saharan trade and later pursued the greater profits of the Asian spice trade.
• Religion and politics: Portugal wanted to spread Christianity and hoped to find the legendary eastern Christian ruler Prester John, believing an alliance could benefit Christian powers.

Rather than building expensive, full-scale colonies everywhere, the Portuguese often established trading posts to support commerce. They set up posts in West Africa and expanded along the African coast. After Vasco da Gama sailed around southern Africa to Calicut, the Portuguese recognized the wealth of Indian Ocean trade and established posts across the region toward Southeast Asia. Armed ships helped them challenge established merchants and assert control over trade.

Spain: Atlantic voyages and American expansion

Spanish monarchs Ferdinand and Isabella sponsored Christopher Columbus after Portugal rejected his proposal to sail west to Asia. In 1492, Columbus reached Caribbean islands, believing he had arrived in the East Indies. Although later voyages did not change his view, other explorers recognized that Europeans had encountered previously unknown continents.

Spain went on to sponsor further exploration and conquest in the Americas. The video also describes Ferdinand Magellan’s expedition as sailing around South America and across the Pacific to the East Indies.

Spanish activity opened up transatlantic trade, which ultimately became more profitable than Indian Ocean trade.

Other European powers

As Portugal and Spain gained wealth and influence, other states entered maritime exploration. Their motives included rivalry, the pursuit of wealth, and the search for alternative routes to Asia.

• France: France sought a westward passage to the Indian Ocean but did not find one. Exploration in North America led to a presence in the fur trade. Samuel de Champlain established Quebec in 1608. French activity relied heavily on trading posts and took place amid disease and conflict with Indigenous peoples, including the Iroquois.
• England: England entered exploration later because its textile industry was already generating substantial profits, making investors less eager to risk money overseas. After Elizabeth I came to power and Spain’s attempted invasion weakened Spain, England supported westward exploration. Sir Walter Raleigh led an expedition that established Virginia. Jamestown, founded in 1607, eventually made the English effort more successful.
• The Dutch: After gaining independence from Spain in 1579, the Dutch became a major European power and competed for trading posts in Africa. They eventually displaced Portugal as the leading force in Indian Ocean trade. In 1608, the Dutch sponsored Henry Hudson’s westward voyage to establish a presence in North America, associated in the video with the colony of New Amsterdam.
