The monarchs of Spain sent Christopher Columbus on his journeys.
Christopher Columbus was an Italian explorer who completed four voyages across the Atlantic Ocean, opening the way for the widespread European exploration and colonization of the Americas. He first received support for his voyages from King Ferdinand II and Queen Isabella I of Spain in 1492. Columbus's voyages led to the establishment of Spanish colonies in the Caribbean, Central, and South America, and a significant impact on the history of the Americas.
