The Age of Exploration began in the 15th century as European powers sought new trade routes and lands. Countries sponsored voyages of explorers like Christopher Columbus, Vasco da Gama, and Ferdinand Magellan to circumnavigate the globe and map the Americas and Asia. These explorations established new trade networks for resources like spices, gold, and slaves, and led to the Columbian Exchange of plants, animals, technologies, and diseases between the Old World and New World.
