Explorer Christopher Columbus (1451–1506), an Italian explorer and navigator, is known for his 1492 ‘discovery’ of the New World of the Americas on board his ship Santa Maria. In actual fact, Columbus did not discover North America. He was the first European to sight the Bahamas archipelago and then the island later named Hispaniola, now split into Haiti and the Dominican Republic. On his subsequent voyages, he went farther south, to Central and South America. He never got close to what is now called the United States.

It is commonly said that "Columbus discovered America." It would be more accurate, perhaps, to say that he introduced the Americas to Western Europe during his four voyages to the region between 1492 and 1502.
