The Age of Exploration, or Age of Discovery, is one of the most important events in the history of the western world. It began in the early 15th century and continued until the end of the 17th century, and involved European explorers using their navigational skills to travel the world. In general, the Age of Exploration occurred for several different reasons, particularly in the countries of Portugal, Spain, France and England. The motivations for exploration included economic, political, religious, intellectual and technological factors.
Each of these countries experienced the same forces that pushed them to explore the world, but they also shared one important characteristic. They were all countries that bordered on the Atlantic Ocean and had easy access to the sea with many sea ports and experienced sailors. This allowed these four nations to have the ability to begin exploring while other European nations did not.
FactsthatCrunchCauses of the Age of Exploration – Economic
First, European countries were seeking new trade routes to distant trading partners in the Far East, including: China, India and Japan. European countries had traditionally traded with these countries through the Silk Road. The Silk RoadAn ancient network of overland trade paths connecting Europe to China, India, and other parts of Asia. was mostly over land and took merchants a great deal of time to ship goods. European countries were interested in speeding up trade by finding a quicker sea route, particularly for valuable resources such as spices, silk, and precious metals.
Furthermore, the overland routes, such as the Silk Road, had become unreliable and expensive due to the fall of Constantinople in 1453 and the rise of the Ottoman Empire. This is because the Ottomans controlled many eastern trade routes and demanded large fees. As such, this motivated European monarchs to fund explorations to find a faster route to the Far East.
Portugal led the way with explorers like Vasco da Gama, who sailed around the whole of Africa and the Cape of Good Hope to reach India. Spain followed, banking on Christopher Columbus’s proposal to reach Asia by sailing west. Though he stumbled upon the Americas instead, the economic potential of these ‘new’ lands became obvious. Gold and silver from the Americas enriched European empires and fueled further exploration.
FactsthatCrunchWhy did the fall of Constantinople in 1453 CE push Europeans to seek sea routes to Asia?
When the Ottoman Empire took control of Constantinople in 1453 CE, it gained power over many of the eastern overland trade routes that merchants had used to reach Asia. The Ottomans charged large fees to European merchants who wanted to move goods along these routes, making trade from China, India, and Japan slow and expensive. European monarchs responded by funding voyages to find a faster sea route to Asia that bypassed Ottoman-controlled lands entirely.
Causes of the Age of Exploration – Political
A second reason for the beginning of the Age of Exploration was the rise of absolute monarchies in Europe. The powerful monarchs of Europe had centralized the authority and wealth of each country and used their vast wealth to fund the expeditions of many explorers. For example, Christopher Columbus was funded by King Ferdinand and Queen Isabella of Spain.
The major European powers were in a constant race to expand their influence around the world. Monarchs saw exploration and colonization as a way to improve their global standing, increase revenue, and establish military outposts in strategically important locations. For instance, as the Spanish and Portuguese built overseas empires, other European nations like England, France, and the Netherlands joined the race, establishing colonies in North America, Africa, and Asia.
FactsthatCrunchWhen absolute monarchs decided to send explorers overseas, a structured system connected royal treasury funding to the crown's legal claim over any new lands found.
Causes of the Age of Exploration – Religious
Religion also played a major role in driving exploration during the Age of Exploration. The Catholic Church, especially through Spain and Portugal, saw overseas expansion as a means to spread Christianity to non-European peoples. As such, missionariesPeople who travel to another country or region to spread their religion’s teachings and beliefs. were often part of the voyages to the New World during the Age of Exploration. In short, missionaries are people who travel to another country or region as a means of spreading religious teachings and beliefs.
The Protestant Reformation in the early 16th century was another important factor in the religious factors that caused the Age of Exploration. For example, Protestant and Catholic nations alike saw exploration as a battleground for religious competition. Religious justification was used to carry out colonization, even when it involved exploitation or violence against the indigenous peoples of the region.
FactsthatCrunchSpain and Portugal sent missionaries alongside explorers, claiming religious conversion as a key purpose of overseas expansion, while Indigenous peoples faced forced change and violence.
Causes of the Age of Exploration – Intellectual
The next reason for why the Age of Exploration began is because Europeans of the time were interested in foreign cultures and goods. In general, the Renaissance in Europe caused an expansion of new ideas and new understandings of the world. Europeans were interested in learning about these new ideas and expanding on their worldviews. In fact, Humanist thinking encouraged the study of geography, astronomy, and natural sciences. There was a growing desire to understand the world. Exploration became not only a means of conquest but also of discovery in the intellectual sense.

Causes of the Age of Exploration – Technological
While motivations were important, none of the exploration would have been possible without the technological breakthroughs of the time. In fact, Europeans had made some dramatic improvements in their navigational skill and technology that allowed early explorers to travel further and more accurately at sea. For example, ship building had drastically improved in the years immediately before the Age of Exploration began. New ships, such as the carrackA large ocean-going sailing ship developed before the Age of Exploration that could carry more cargo on longer voyages. and the caravelA smaller, maneuverable sailing ship used by early explorers to travel farther into unknown waters., allowed explorers to hold more cargo and venture further than ever before. As well, other advances in navigation, such as the magnetic compass, astrolabeA navigation instrument that helped sailors determine their position at sea by measuring the angle of stars., and more accurate maps (cartography), made longer sea voyages more achievable.

Frequently Asked Questions
When did the Age of Exploration take place?
The Age of Exploration began in the early 15th century and lasted until the end of the 17th century. During this time, European explorers used new navigation skills to travel across the world. It is also called the Age of Discovery. Portugal and Spain led the earliest voyages.
Which countries led the Age of Exploration and why?
Portugal, Spain, France, and England led the Age of Exploration. These four nations all bordered the Atlantic Ocean, which gave them easy access to the sea. They had many sea ports and large numbers of experienced sailors. This location gave them an advantage that other European nations did not share.
How did the fall of Constantinople cause exploration?
The fall of Constantinople in 1453 made overland trade routes unreliable and expensive. The rising Ottoman Empire controlled many eastern routes and demanded large fees from merchants. This made goods from the Far East costly to bring to Europe. As a result, monarchs funded voyages to find a faster sea route to Asia.
What role did religion play in the Age of Exploration?
The Catholic Church saw overseas expansion as a way to spread Christianity to non-European peoples. Missionaries often joined voyages to the New World to teach their beliefs. The Protestant Reformation of the early 16th century added more religious competition. Both Catholic and Protestant nations used faith to justify colonization.
What technology made the Age of Exploration possible?
New ships and navigation tools made long sea voyages possible for the first time. The carrack and caravel let explorers carry more cargo and travel farther than before. The magnetic compass and astrolabe helped sailors find their position at sea. More accurate maps, known as cartography, also improved long journeys.
Who funded Christopher Columbus and what did he find?
King Ferdinand and Queen Isabella of Spain funded Christopher Columbus and his four voyages. He planned to reach Asia by sailing west across the Atlantic Ocean. Instead, he reached the Americas in 1492, which Europeans had not known about. Gold and silver from these lands later enriched European empires.
