Columbus’s early life is somewhat obscure, but scholars generally agree that he was born in the Republic of Genoa and spoke a dialect of Ligurian as his first language. He went to sea at a young age and travelled widely, as far north as the British Isles (and possibly Iceland) and as far south as what is now Ghana. He married Portuguese noblewoman Filipa Moniz Perestrelo and was based in Lisbon for several years, but later took a Castilian mistress; he had one son with each woman. Though largely self-educated, Columbus was widely read in geography, astronomy, and history. He formulated a plan to seek a western sea passage to the East Indies, hoping to profit from the lucrative spice trade. Following persistent lobbying, Queen Isabella I and King Ferdinand II agreed to sponsor a journey west, in the name of the Crown of Castile. Columbus left Castile in August 1492 with three ships, and after a stopover in the Canary Islands made landfall in the Americas on 12 October (later celebrated as Columbus Day). His landing place was an island in the Bahamas, known by its native inhabitants as Guanahani; its exact location is uncertain. Columbus subsequently visited the islands now known as Cuba and Hispaniola, establishing a colony in what is now Haiti—the first European settlement in the Americas since the Norse colonies nearly 500 years earlier. He arrived back in Castile in early 1493, bringing a number of captive natives with him. Word of his voyages soon spread throughout Europe.
