Which of the following was a major motivation for European maritime expansion starting in the 15th century?

European exploration

In the 100 years from the mid-15th to the mid-16th century, a combination of circumstances stimulated men to seek new routes, and it was new routes rather than new lands that filled the minds of kings and commoners, scholars and seamen. First, toward the end of the 14th century, the vast empire of the Mongols was breaking up; thus, Western merchants could no longer be assured of safe-conduct along the land routes. Second, the Ottoman Turks and the Venetians controlled commercial access to the Mediterranean and the ancient sea routes from the East. Third, new nations on the Atlantic shores of Europe were now ready to seek overseas trade and adventure.

European exploration of the African coast

Henry the Navigator, prince of Portugal, initiated the first great enterprise of the Age of Discovery—the search for a sea route east by south to Cathay. His motives were mixed. He was curious about the world; he was interested in new navigational aids and better ship design and was eager to test them; he was also a Crusader and hoped that, by sailing south and then east along the coast of Africa, Arab power in North Africa could be attacked from the rear. The promotion of profitable trade was yet another motive; he aimed to divert the Guinea trade in gold and ivory away from its routes across the Sahara to the Moors of Barbary (North Africa) and instead channel it via the sea route to Portugal.

Expedition after expedition was sent forth throughout the 15th century to explore the coast of Africa. In 1445 the Portuguese navigator Dinís Dias reached the mouth of the Sénégal, which “men say comes from the Nile, being one of the most glorious rivers of Earth, flowing from the Garden of Eden and the earthly paradise.” Once the desert coast had been passed, the sailors pushed on: in 1455 and 1456 Alvise Ca’ da Mosto made voyages to Gambia and the Cape Verde Islands. Prince Henry died in 1460 after a career that had brought the colonization of the Madeira Islands and the Azores and the traversal of the African coast to Sierra Leone. Henry’s captain, Diogo Cão, discovered the Congo River in 1482. All seemed promising; trade was good with the riverine peoples, and the coast was trending hopefully eastward. Then the disappointing fact was realized: the head of a great gulf had been reached, and, beyond, the coast seemed to stretch endlessly southward. Yet, when Columbus sought backing for his plan to sail westward across the Atlantic to the Indies, he was refused—“seeing that King John II [of Portugal] ordered the coast of Africa to be explored with the intention of going by that route to India.”

John II of Portugal

King John II sought to establish two routes: the first, a land and sea route through Egypt and Ethiopia to the Red Sea and the Indian Ocean and, the second, a sea route around the southern shores of Africa, the latter an act of faith, since Ptolemy’s map showed a landlocked Indian Ocean. In 1487, a Portuguese emissary, Pêro da Covilhã, successfully followed the first route; but, on returning to Cairo, he reported that, in order to travel to India, the Portuguese “could navigate by their coasts and the seas of Guinea.” In the same year, another Portuguese navigator, Bartolomeu Dias, found encouraging evidence that this was so. In 1487 he rounded the Cape of Storms in such bad weather that he did not see it, but he satisfied himself that the coast was now trending northeastward; before turning back, he reached the Great Fish River, in what is now South Africa. On the return voyage, he sighted the Cape and set up a pillar upon it to mark its discovery.

history of Europe: Discovery of the New World

In the Iberian Peninsula the impetus of the counteroffensive against the Moors carried the Portuguese to probe the West African coastline...

The seaway was now open, but eight years were to elapse before it was exploited. In 1492 Columbus had apparently reached the East by a much easier route. By the end of the decade, however, doubts of the validity of Columbus’s claim were current. Interest was therefore renewed in establishing the sea route south by east to the known riches of India. In 1497 a Portuguese captain, Vasco da Gama, sailed in command of a fleet under instructions to reach Calicut (Kozhikode), on India’s west coast. This he did after a magnificent voyage around the Cape of Storms (which he renamed the Cape of Good Hope) and along the unknown coast of East Africa. Yet another Portuguese fleet set out in 1500, this one being under the command of Pedro Álvarez Cabral; on the advice of da Gama, Cabral steered southwestward to avoid the calms of the Guinea coast; thus, en route for Calicut, Brazil was discovered. Soon trading depots, known as factories, were built along the African coast, at the strategic entrances to the Red Sea and the Persian Gulf, and along the shores of the Indian peninsula. In 1511 the Portuguese established a base at Malacca (now Melaka, Malaysia), commanding the straits into the China Sea; in 1511 and 1512, the Moluccas, or Spice Islands, and Java were reached; in 1557 the trading port of Macau was founded at the mouth of the Canton River. Europe had arrived in the East. It was in the end the Portuguese, not the Turks, who destroyed the commercial supremacy of the Italian cities, which had been based on a monopoly of Europe’s trade with the East by land. But Portugal was soon overextended; it was therefore the Dutch, the English, and the French who in the long run reaped the harvest of Portuguese enterprise.

Some idea of the knowledge that these trading explorers brought to the common store may be gained by a study of contemporary maps. The map of the German Henricus Martellus, published in 1492, shows the shores of North Africa and of the Gulf of Guinea more or less correctly and was probably taken from numerous seamen’s charts. The delineation of the west coast of southern Africa from the Guinea Gulf to the Cape suggests a knowledge of the charts of the expedition of Bartolomeu Dias. The coastlines of the Indian Ocean are largely Ptolemaic with two exceptions: first, the Indian Ocean is no longer landlocked; and second, the Malay Peninsula is shown twice—once according to Ptolemy and once again, presumably, according to Marco Polo. The Contarini map of 1506 shows further advances; the shape of Africa is generally accurate, and there is new knowledge of the Indian Ocean, although it is curiously treated. Peninsular India (on which Cananor and Calicut are named) is shown; although too small, it is, however, recognizable. There is even an indication to the east of it of the Bay of Bengal, with a great river running into it. Eastward of this is Ptolemy’s India, with the huge island of Taprobane—a muddled representation of the Indian peninsula and Ceylon (now Sri Lanka). East again, as on the map of Henricus Martellus, the Malay Peninsula appears twice. Ptolemy’s bonds were hard to break.

Europe emerged from an age of isolation with a desire to explore. In contrast to the Chinese, whose voyages were motivated mainly by a need to bolster their international prestige, European voyages during the Age of Exploration were motivated mainly by financial interests. The Asian goods that Europe purchased, such as pepper, ginger, cloves, and nutmeg, were significantly expensive. Europeans wanted to gain direct access to these goods, increasing supply and lowering prices. Other motives included the spread of Christianity and the desire for adventure. Read on to learn about the countries involved in European exploration and the role it played in the world.

European Exploration: Portugal

The rough landscape of Portugal was not ideal farmland, and the kingdom was an impoverished one prior to the Age of Exploration. This economic deficiency motivated interest in both accessing luxury goods more cheaply and also in improving Portugal’s finances. While the Portuguese nobility was interested in conquering Morocco, its monarchy sought to control the spice trade by finding a sea route to India. There was also interest in locating the kingdom of Prester John, a supposed Christian ruler somewhere in Africa, to form an alliance against Islam.

The Portuguese were early leaders in exploration, under the leadership of Prince Henry the Navigator, who established Portuguese schools and sponsored expeditions along the West African coast. The key innovation of Portuguese navigators was the discovery of the volta do mar (literally “turn of the sea”), trade winds that allowed ships to easily sail past the west coast of Africa. This required the counterintuitive step to sail far westward into the open ocean to catch winds that would bring ships back around to the southern tip of Africa, with Bartolomeu Dias rounding the Cape of Good Hope in 1488. The Portuguese first arrived in India in 1498; the first Indian voyage lost a third of its crew but made 60 times a return on the investment of the expedition.

The Portuguese were methodical in their exploration, carefully recording winds, sea currents, tides, port locations, and more. They conducted live trials of their cannons at sea, figuring out how to best sink enemy ships and bombard coastal targets. Despite India hosting a gunpowder The Portuguese were methodical in their exploration, carefully recording winds, sea currents, tides, port locations, and more. They conducted live trials of their cannons at sea, figuring out how to best sink enemy ships and bombard coastal targets. Despite India hosting a gunpowder empire at the time, Portuguese artillery was superior. Instead of bows, which were still in use in many places throughout Afro-Eurasia, they used crossbows and muskets and had superior armor. All these advantages allowed Portugal to establish a major, lucrative empire. 

European Exploration: Spain

It is a myth that Christopher Columbus sought to prove that the Earth was round, which was a long-established fact even by 1492. Portuguese mathematicians had calculated the size of the Earth and dismissed the claim of Columbus that one could sail westward to Asia. What they were unaware of was the existence of the Americas. Spain, having just completed the Reconquista, sought a way to bypass the Portuguese monopoly on sea routes along West Africa.

While Portugal would build its empire in the Eastern Hemisphere, Spain mainly conquered the Americas. Spain did, however, conquer the Philippines, which had first been explored under Ferdinand Magellan, along with several small islands in the Pacific such as Guam.

Spanish and Portuguese Colonies in the New World

Spanish conquistadors led the way in the conquest of the Americas. The primary Spanish settle- ments, New Spain (Mexico) and New Castile (Peru), were each governed by a viceroy, who reported directly to the Spanish king. In 1494, the Treaty of Tordesillas, an agreement between Spain and Portugal based on an earlier decree by Pope Alexander VI, divided control of any future American territories: the Spanish controlled the land west of the agreed-upon line of demarcation, and the Portuguese controlled the territory east of the line.

Along with its goal of increasing wealth through the creation of an empire, Spain desired to expand the influence of Christianity. Catholic missionaries came to the Americas alongside the conquistadors and built mission churches to convert American Indians, many of whom adopted Christianity but blended it with their indigenous religions. For the most part, however, these Spanish missionaries forcibly imposed European culture on the natives.

The social result of the conquest of this new empire was a multicultural and ethnically mixed population. The peninsulares, the highest social class, came directly from the Iberian peninsula, and their American-born descendants were called Creoles. Those of mixed European and American Indian descent were called mestizos, and those with European and African ancestors were called mulattos. At the bottom of the social order were the American Indians, Africans, and the mixed class of zambos. 

European Exploration: The Dutch

Dutch exploration during this period is practically synonymous with the Dutch East India Company, a massive business conglomerate with monopolies in several areas, which served as the right arm of the Dutch Republic. The Dutch East India Company was a model for the British East India Company. The Dutch Empire consisted mainly of its holdings in the East Indies (present-day Indonesia), the Cape Colony (present-day South Africa), and scattered holds in the Americas, India, and China.

As with France, the high standards of living in the Dutch Republic did little to motivate citizens to emigrate abroad to colonial holdings. Some of its outposts like New Amsterdam (present-day New York City) were eventually absorbed by rival, expansionist European powers. 

European Exploration: England

English voyages were mainly concentrated on North America and India. John Cabot, an Italian employed by Henry VII, explored coastal North America. Sir Francis Drake carried out the second circumnavigation of the world and was the first captain to survive the entire voyage. Unlike the other European powers, England strongly favored settler colonies. While it would eventually become a global superpower, England at the start of the Age of Exploration was a fairly impoverished sector of Europe, which motivated some people to emigrate to its overseas holdings. Its culture also associated political rights and freedom with land ownership.

While the British East India Company initially struggled against its Dutch counterpart, the British eventually gained a secure foothold in India, expanding over time until it controlled most of the subcontinent and had shut out European rivals, such as through the Anglo-Dutch Wars. 

European Exploration: France

France likewise focused on the spice trade in India as well as exploration of North America. Jacques Cartier claimed much of what is present-day Canada for France and was the first European to travel inland in North America. While settlements were made in what was then called New France, the comparative wealth of France itself did not motivate much emigration to rough frontier forts and villages. 

The Development of the Global Economy

Maritime Technology

The Ottoman conquest of Constantinople in 1453 ended the Byzantine Empire, solidifying Muslim influence along the Silk Road and making it less friendly to European traders. The acquisition of technology from China and the Muslim world helped Europeans expand their seagoing capabilities with maritime equipment such as the sternpost rudder, triangular lateen sails, the magnetic compass, and the astrolabe.

Portugal was an early leader in European exploration, aided by the development of the caravel, a small, highly maneuverable sailing ship. The lateen sail (French for “Latin”) dates back to Roman times, but was popularized during the Age of Exploration for its ability to let a boat tack against the wind, increasing maneuverability. This proved useful when sailing out into the Atlantic Ocean to catch the trade winds, but its size was cumbersome, especially during storms. The weaknesses of the lateen sail, and the harsh requirements of long-distance ocean travel, led to the Portuguese developing the carrack, a larger and more rugged sailing vessel with three to four masts. However, other nations innovated as well. In the sixteenth century, the Dutch developed the fluyt, a dedicated transoceanic cargo vessel that was a key factor in the rise of the Dutch Empire. At their height in the seventeenth century, fluyts carried roughly half of all European cargo. 

Trading-Post Empires

The initial goal of European powers in exploring the Indian Ocean was not to conquer, but to control trade. They wanted to force merchant ships to trade in fortified trading sites and to pay duties for the privilege. By the mid 1500s, Portugal had 50 trading posts from West Africa to East Asia, but by the late 1500s its power had started to decline—the country lacked the administrative and military capabilities to keep up with other European powers. The death of King Sebastian I and a large portion of the Portuguese nobility at the Battle of Alcácer Quibir in 1578 in northern Morocco sparked a succession crisis that destabilized the country. Soon, Spain absorbed Portugal and its empire, with Portugal only regaining independence in 1640.

The English and Dutch quickly took Portugal’s place as the dominant seafaring powers with faster, cheaper, and more powerful ships. Their imperial expansion was aided by the use of joint-stock companies, in which investors, rather than royal governments, funded expeditions. 

Reaction to European Expansion

Ming China

Following the voyages of Zheng He, Ming China pursued an isolationist foreign policy. While the Ming restricted European trade to islands like Macau, China still benefited enormously from the Columbian Exchange. New crops like corn and potatoes fueled population growth, offered a cushion against famine, and became staples of regional Chinese cuisine. The influx of New World silver revitalized the Chinese economy, which had suffered from inflation from an oversupply of paper money, but created a trade imbalance that would eventually lead to the Opium Wars. The enactment of the Japanese sakoku policy, as well as anti-smuggling efforts by the Spanish, disrupted the flow of silver into China, contributing to the rise of the Qing Dynasty as the Chinese economy collapsed. 

Tokugawa Japan

Initially, the shogunate allowed foreign trade, which it monopolized for great financial benefit. However, European influence gradually came to be seen as a threat to the shogunate’s power structure, as foreign trade could potentially enrich the daimyo enough to allow them to unseat the shogunate. The sakoku (“closed country”), a strictly isolationist foreign policy, was enacted in 1633 and would last until 1853. Nevertheless, highly regulated contact was maintained in the city of Nagasaki with the Dutch, while the Koreans had limited contact as well. “Dutch learning” from the West primed Japan for the Meiji Restoration. The then-burgeoning Christian community in Japan was suppressed and all but wiped out. 

Kingdom of Kongo

In the fourteenth century, the Kongo emerged as a centralized state along the west coast of central Africa. In this organized state, a powerful king ruled, and officials oversaw military, judicial, and financial affairs. In 1483, a small Portuguese fleet arrived and initiated commercial relations, and within a few years the Portuguese had developed a close political and diplomatic relationship with the king. To improve relations, kings like Affonso I converted to and spread Catholicism across the kingdom, although the local version of Catholicism syncretized local religion practices.

The Portuguese brought great wealth to Kongo, exchanging textiles and weapons for gold, silver, ivory, and slaves. Kongo became a major hub of the transatlantic slave trade and often sourced the slaves it forcibly exported from those captured during Kongo’s expansionist wars. Eventually, the Portuguese dealings undermined the king’s authority and led to conflict. Moreover, relations with the Portuguese would sour over time, leading to a series of wars with the Portuguese. These wars often tied into dynastic succession issues within the Kingdom of Kongo over which family—and sometimes which member within which family—should rule. The kingdom never fully recovered from these wars.
