Christopher Columbus landed in Hispaniola thinking he had found India. Columbus was an Italian explorer and navigator from the Republic of Genoa who completed four Spanish-based voyages across the Atlantic Ocean sponsored by the Catholic Monarchs, opening the way for the widespread European exploration and European colonization of the Americas. Columbus left Castile in August 1492 with three ships and made landfall in the Americas on October 12, 1492, ending the period of human habitation in the Americas now referred to as the pre-Columbian era. His landing place was an island in the Bahamas, known by its native inhabitants as Guanahani. He then visited the islands now known as Cuba and Hispaniola, establishing a colony in what is now Haiti.
