On his first voyage to the New World, Christopher Columbus (1451-1506) initially landed on the island of Guanahani on October 13, 1492. He named the island San Salvador; the exact location of this bit of land is still uncertain, but it was probably part of the present day Bahamas or, possibly, Turks and Caicos. The Bahamas named one of their islands San Salvador Island in 1925, believing it to be the spot of Columbus' landing. Later on his first voyage, Columbus became the first European to land on Cuba (October 28) and Hispaniola (December 5), the island on which Haiti and the Dominican Republic exists today.
There is no proof that Columbus reached other islands on his first voyage, but upon his return to the Americas a year later, he spotted Dominica before landing on Marie-Gallante, an island in the Guadaloupe chain. He explored Guadaloupe before later landing on Puerto Rico.
