The explorer Christopher Columbus made four trips across the Atlantic Ocean from Spain: in 1492, 1493, 1498, and 1502. He was determined to find a direct water route west from Europe to Asia, but he never did. Instead, he stumbled upon the Americas. Though he did not really “discover” the so-called New World—millions of people already lived there—his journeys marked the beginning of centuries of exploration and colonization of North and South America.
