How did European exploration change over time?

European exploration evolved significantly from the late 15th century through the 18th century. Initially driven by the search for new trade routes and the spread of Christianity, explorers like Columbus and Vasco da Gama focused on establishing direct access to Asia. Over time, motivations shifted towards imperial expansion, resource extraction, and colonization, as seen in the establishment of empires by Spain, Portugal, England, and France. Additionally, advancements in navigation technology and mapping facilitated deeper and more sustained exploration of Africa, the Americas, and the Pacific.
