Christopher Columbus was born around 1451, probably in the Republic of Genoa. He became a sailor at a young age and spent years gaining experience in Mediterranean and Atlantic waters.
Columbus developed a plan to reach Asia by sailing westward across the Atlantic. He initially sought support from several European rulers before gaining the backing of Ferdinand of Aragon and Isabella of Castile.
In August 1492, Columbus sailed from Spain with three ships: the Santa María, the Pinta and the Niña. In October, the expedition reached islands in the Caribbean.
Columbus believed that he had reached regions of Asia. He made three additional voyages across the Atlantic, exploring parts of the Caribbean and northern South America.
His voyages became a turning point in global history, although they also contributed to European conquest, colonization, enslavement and severe disruption of Indigenous societies.
