Christopher Columbus, by Mildred Stapley, is a definitive biography of the great Italian explorer. Christopher Columbus was an Italian explorer, navigator, and colonizer. Born in the Republic of Genoa, under the auspices of the Catholic Monarchs of Spain he completed four voyages across the Atlantic Ocean. Those voyages and his efforts to establish settlements on the island of Hispaniola, initiated the permanent European colonization of the New World. At a time when European kingdoms were beginning to establish new trade routes and colonies, motivated by imperialism and economic competition, Columbus proposed to reach the East Indies (South and Southeast Asia) by sailing westward. This eventually received the support of the Spanish Crown, which saw a chance to enter the spice trade with Asia through this new route. During his first voyage in 1492, he reached the New World instead of arriving in Japan as he had intended, landing on an island in the Bahamas archipelago that he named San Salvador. Over the course of three more voyages, he visited the Greater and Lesser Antilles, as well as the Caribbean coast of Venezuela and Central America, claiming all of it for the Crown of Castile. Though preceded by short-lived Norse colonization of North America led by Leif Erikson in the 11th century, Columbus is the European explorer credited with establishing and documenting routes to the Americas, securing lasting European ties to the Americas, and inaugurating a period of exploration, conquest, and colonization that lasted for centuries. His exertions thereby strongly contributed to the development of the modern Western world. He also founded the transatlantic slave trade and has been accused by several historians of initiating the genocide of the Hispaniola natives. Columbus himself saw his accomplishments primarily in the light of spreading the Catholic religion. Columbus had set course in hopes of finding a western route to the Indies (Asia). He called the inhabitants of the lands that he visited indios (Spanish for "Indians"). His strained relationship with the Spanish crown and its appointed colonial administrators in America led to his arrest and dismissal as governor of the settlements on the island of Hispaniola in 1500, and later to protracted litigation over the benefits that he and his heirs claimed were owed to them by the crown.
