Age of Exploration

Grade 7 · Social Studies · Study Guide

Between the 15th and 17th centuries, European explorers set sail to find new trade routes and ended up connecting the entire globe for the first time in history.

The Age of Exploration (roughly 1400-1700 CE) was driven by European desire to find direct sea routes to Asia to bypass Muslim-controlled overland trade routes. Portugal led the early effort, with Prince Henry the Navigator funding expeditions down the African coast. Vasco da Gama eventually sailed around Africa and reached India in 1498. Spain funded Christopher Columbus, who crossed the Atlantic in 1492 expecting to reach Asia and instead made first contact with the Americas.

The 'discovery' of the Americas launched an era of European colonization. Spanish conquistadors like Cortes and Pizarro conquered the Aztec and Inca empires with devastating speed, aided by disease and indigenous allies. Portugal claimed Brazil, while Spain built a vast colonial empire across the Americas. Ferdinand Magellan's expedition (1519-1522) became the first to circumnavigate the globe, proving Earth's true size and shape.

The Columbian Exchange was the transfer of plants, animals, diseases, and people between the Old World (Europe, Africa, Asia) and New World (the Americas). Europeans brought horses, cattle, wheat, and deadly diseases to the Americas. The Americas contributed potatoes, corn (maize), tomatoes, chocolate, and tobacco to the rest of the world. These exchanges permanently transformed diets, economies, and populations on both sides of the Atlantic.
