There were multiple main causes for the European Age of Exploration, which led to the discovery of new continents and lands that were previously unknown to Europeans. These include:

- Religious Motives: The Crusades, a series of religious wars initiated by European Christians to recapture the Holy Land, exposed Europeans to new cultures and created interest in exploring the world.

- Technological Advancements: Improvements in shipbuilding and navigation techniques like the astrolabe and the compass allowed for longer and more accurate sea voyages.

- Renaissance Humanism: A cultural movement that emphasized the importance of knowledge and human potential encouraged exploration and scientific discovery.

- Portuguese and Spanish Expansion: Portugal and Spain, with their geographic location and early advancements in seafaring, played a significant role in leading exploration efforts.

- Competition and Prestige: A spirit of competition between European nations to claim new lands and establish global empires contributed to exploration efforts.

- Geographic Curiosity: Some explorers were driven by a genuine desire to learn more about the unknown world and its geography.
