Backed by Spain's Ferdinand and Isabella, Columbus sailed west across the Atlantic seeking a direct route to Asia. After weeks at sea, his crew sighted land in the Bahamas.
He believed he had reached the Indies and never accepted he had found a new continent. His voyages opened the door to European colonization of the Americas.
The encounter triggered one of history's largest biological and cultural exchanges, with profound and often tragic consequences for Indigenous peoples.
"He set out for Cathay and found a continent. The encounter between two worlds began in a single landing on a Bahamian shore."
Columbus's voyage initiated sustained contact between the Americas and Europe, unleashing the Columbian Exchange of goods, peoples, and disease. It launched the conquest and colonization that remade the globe and devastated Indigenous civilizations.
Columbus underestimated the Earth's circumference and expected Asia. The existence of the Americas defied the maps he trusted.
Crops, animals, and diseases crossed the ocean in both directions, transforming diets and populations on every continent.
Celebrated for centuries as a discoverer, Columbus is now debated for the conquest and catastrophe his voyages set in motion.
