Christopher Columbus (c. 31 October 1451 – 20 May 1506) was an explorer, colonizer, and navigator, born in the Republic of Genoa, in northwestern Italy. Under the auspices of the Catholic Monarchs of Spain, he completed four voyages across the Atlantic Ocean that led to general European awareness of the American continents in the Western Hemisphere. Those voyages, and his efforts to establish permanent settlements in the island of Hispaniola, initiated the process of Spanish colonization, which foreshadowed the general European colonization of the "New World".

In the context of emerging western imperialism and economic competition between European kingdoms seeking wealth through the establishment of trade routes and colonies, Columbus' far-fetched proposal to reach the East Indies by sailing westward received the support of the Spanish crown, which saw in it a promise, however remote, of gaining the upper hand over rival powers in the contest for the lucrative spice trade with Asia. During his first voyage in 1492, instead of reaching Japan as he had intended, Columbus landed in the Bahamas archipelago, at a locale he named San Salvador. Over the course of three more voyages, Columbus visited the Greater and Lesser Antilles, as well as the Caribbean coast of Colombia, Venezuela and Central America, claiming them for the Spanish Empire.
