Christopher Columbus discovered the West Indies in 1492. He was an Italian explorer who set sail from Spain in search of a new route to India. He landed in the Bahamas on October 12, 1492, and believed that he had reached India. He continued to explore the Caribbean, and eventually landed in what is now Cuba. He returned to Spain in triumph, and was given the title of “Admiral of the Ocean Sea.” He made three more voyages to the Americas, but never reached India.
