On October 12, 1492, the ships under Christopher Columbus command sighted the land in the Bahamas and later they landed at the Islands of Cuban and Haiti. Columbus is Genoese navigator and explorer whose transatlantic voyages opened the way for European exploration, exploitation, and colonization of the Americas. He began his career as a young seaman in the Portuguese merchant marine. In 1492 he obtained the sponsorship of the Spanish monarchs Ferdinand V and Isabella I for an attempt to reach Asia by sailing westward over what was presumed to be open sea. On his first voyage he set sail in August 1492 with three ships,the Santa María, the Niña, and the Pinta and land was sighted in the Bahamas on October 12. He sailed along the northern coast of Hispaniola and returned to Spain in 1493. He made a second voyage (1493-96) with at least 17 ships and founded La Isabela (in what is now the Dominican Republic), the first European town in the New World. This voyage also began Spain’s effort to promote Christian evangelization. On his third voyage (1498-1500) he reached South America and the Orinoco River delta. Allegations of his poor administration led to his being returned to Spain in chains. On his fourth voyage (1502-04) he returned to South America and sailed along the coasts of present-day Honduras and Panama. He was unable to attain his goals of nobility and great wealth. His character and achievements have long been debated, but scholars generally agree that he was an intrepid and brilliant navigator.
