Christopher Columbus: The Navigator Who Changed the Map of the World

Christopher Columbus's 1492 voyage across the Atlantic Ocean initiated permanent contact between Europe and the Americas, setting in motion one of the most consequential transformations in human history. Born in Genoa around 1451, Columbus was a skilled navigator and a relentless self-promoter who convinced the Spanish monarchs Ferdinand and Isabella to fund an expedition westward to Asia. He never reached Asia, and he never understood that he had encountered continents unknown to Europeans, but his four voyages between 1492 and 1504 opened the door to European colonization, the Columbian Exchange of plants, animals, and diseases, and the reshaping of global civilization - for both extraordinary good and catastrophic harm.

Christopher Columbus was born Cristoforo Colombo around 1451 in the Republic of Genoa, a maritime trading power on the Italian coast. His father was a wool weaver and small-time trader, and young Christopher went to sea as a teenager, sailing the Mediterranean trade routes that connected Europe, North Africa, and the eastern Mediterranean. He survived a shipwreck off the coast of Portugal in 1476 and settled in Lisbon, then the center of European maritime exploration.

The late fifteenth century was a period of intense European maritime expansion driven by the desire for direct trade routes to Asia. The Ottoman Empire's control of eastern Mediterranean trade routes made overland commerce expensive and dangerous. Portugal, under Prince Henry the Navigator and his successors, had been systematically exploring the African coast, seeking a sea route around Africa to India. Columbus conceived a different plan: sailing west across the Atlantic to reach the Indies.

His plan was based on a significant geographical error. Columbus used calculations from the ancient geographer Ptolemy and the Florentine scholar Toscanelli that dramatically underestimated the circumference of the earth and the width of the Atlantic. Most educated Europeans understood the earth was round - that was not the debate - but they correctly estimated the distance to Asia as far too great for the ships of the day. Columbus was wrong about the distance; he was saved by the existence of continents that no European expected.
