The Age of Discovery (1418 – 1620), also known as the Age of Exploration, was part of the early modern period and largely overlapped with the Age of Sail. It was a period from approximately the late 15th century to the 17th century, during which seafarers from a number of European countries explored, colonized, and conquered regions across the globe.
The Age of Discovery was a transformative period in world history when previously isolated parts of the world became connected to form the world-system and laid the groundwork for globalization. The extensive overseas exploration, particularly the opening of maritime routes to the Indies and the European colonization of the Americas by the Spanish and Portuguese, later joined by the English, French and Dutch, spurred in the International global trade. The interconnected global economy of the 21st century has its origins in the expansion of trade networks during this era.
The exploration also created colonial empires and marked an increased adoption of colonialism as a government policy in several European states. As such, it is sometimes synonymous with the first wave of European colonization. The colonization reshaped power dynamics causing geopolitical shifts in Europe and creating new centers of power beyond Europe. Having set human history on the global common course, the legacy of the Age still shapes the world today.
European oceanic exploration started with the maritime expeditions of Portugal to the Canary Islands in 1336, and later with the Portuguese discoveries of the Atlantic archipelagos of Madeira and Azores, the coast of West Africa in 1434, and the establishment of the sea route to India in 1498 by Vasco da Gama, which initiated the Portuguese maritime and trade presence in Kerala and the Indian Ocean.
During the Age of Discovery, Spain sponsored and financed the transatlantic voyages of the Italian navigator Christopher Columbus, which from 1492 to 1504 marked the start of colonization in the Americas, and the expedition of the Portuguese explorer Ferdinand Magellan to open a route from the Atlantic Ocean to the Pacific, which later achieved the first circumnavigation of the globe between 1519 and 1522.
These Spanish expeditions significantly impacted the European perceptions of the world. These discoveries led to numerous naval expeditions across the Atlantic, Indian, and Pacific Oceans, and land expeditions in the Americas, Asia, Africa, and Australia that continued into the late 19th century, followed by the exploration of the polar regions in the 20th century.
European exploration initiated the Columbian exchange between the Old World (Europe, Asia, and Africa) and the New World (the Americas and Australia). This exchange involved the transfer of plants, animals, human populations (including slaves), communicable diseases, and culture across the Eastern and Western Hemispheres.
The Age of Discovery and European exploration involved mapping of the world, shaping a new worldview and facilitating contact with distant civilizations. The continents drawn by European mapmakers of the Age developed from abstract "blobs" into the outlines more recognizable to us today. Simultaneously, the spread of new diseases, especially affecting American Indians, led to rapid population declines.
The era saw widespread enslavement, exploitation and military conquest of native populations, concurrent with the growing economic influence and spread of western and European culture, science and technology leading to a faster-than-exponential population growth world-wide.
Age of Discovery the Catholic Church:
During the Age of Discovery, the Catholic Church inaugurated a major effort to spread Christianity in the New World and to convert the Native Americans and other indigenous people. The missionary effort was a major part of, and a partial justification for the colonial efforts of European powers such as Spain, France and Portugal.
The idea of European exploration and Christian expansion were synonymous with each other as European Christians' religious views and settlements in new lands were a way to convert the indigenous peoples. Christian Missions to the indigenous peoples ran hand-in-hand with the colonial efforts of Catholic nations. In the Americas and other colonies in Asia and Africa, most missions were run by religious orders such as the Augustinians, Franciscans, Jesuits and Dominicans.
In both Portugal and Spain, religion was an integral part of the state and Christianization was seen as having both secular and spiritual benefits. Portuguese explorers would propose ideas of venturing into new territories to religious executives, which were approved based on the idea that "honor and glory will befall not only all of Christendom but also … this most sacred See of Peter."
Wherever these powers attempted to expand their territories or influence, missionaries would soon follow. By the Treaty of Tordesillas, the two powers divided the world between them into exclusive spheres of influence, trade and colonization. The Roman Catholic world order was challenged by the Netherlands and England.
Theoretically, it was repudiated by Grotius's Mare Liberum. Portugal's and Spain's colonial policies were also challenged by the Roman Catholic Church itself. The Vatican founded the Congregatio de Propaganda Fide in 1622 and attempted to separate the churches from the influence of the Iberian kingdoms.
