On August 3, 1492, the Italian navigator Christopher Columbus set sail from the Port of Palos de la Frontera in the Province of Huelva, from the newly los Reyes Católicos coordinated Kingdoms of Castile and Aragon, in present-day Spain, financed by Queen Isabella I of Castille. Columbus's Letter on the First Voyage of his discovery of the Bahamas, Cuba, and Hispaniola spread the news across Europe quickly. Columbus rediscovered and explored much of the Lesser Antilles in his second voyage then discovered both Trinidad and Tobago on his third voyage whilst skirting the northern South American coast. His fourth voyage was spent scanning the Central American 
Title: Christopher Columbus's journal
Content:  The story of Christopher Columbus's origins and young life preceding his sea-faring voyages is still largely unknown.  Columbus survived the sinking of a Portuguese ship, worked for a merchant, and began mapping with his brother Bartholomew before his marriage to Dona Filipa Moniz Perestrelo in 1478. Columbus was interested in studying geography, philosophy, theology, and history. Columbus lived the life of a wandering traveler through his ocean-oriented profession until 1480. Through inaccurate calculations and estimates, Columbus believed that he could successfully travel west to east in order to open up a new trade route to the East Indies. Initially, Columbus presented his potential trade passage to John

Content:   On 30 May 1498, Columbus left with six ships from Sanlúcar, Spain. Three of the ships headed directly for Hispaniola with much-needed supplies. Columbus took the other three to continue the search for a passage to continental Asia. On 31 July they sighted Trinidad. On 1 August, they arrived near the mouth of South America's Orinoco river. Columbus recognized that it must be the continent's mainland. On 5 August, they landed on the mainland of South America at the Paria Peninsula. They then sailed to the islands of Chacachacare and Margarita (reaching the latter on 14 August), and sighted Tobago and Grenada. On 19 August, Columbus returned to Hispaniola. There he

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. 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 Columbus's persistent lobbying to multiple kingdoms, Catholic Monarchs Queen Isabella I and King Ferdinand II agreed to sponsor a journey west. Columbus left Castile in August 1492 with three ships and made landfall in the Americas on 12 October (ending the period of human habitation in the Americas now 
Title: Christopher Columbus
Content:  Christopher Columbus (born between 25 August and 31 October 1451, died 20 May 1506) was an Italian explorer and navigator who completed four voyages across the Atlantic Ocean, opening the way for the widespread European exploration and colonization of the Americas. His expeditions, sponsored by the Catholic Monarchs of Spain, were the first European contact with the Caribbean, Central America, and South America. The name Christopher Columbus is the Anglicisation of the Latin Christophorus Columbus. Scholars generally agree that Columbus 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 as 
Title: History of chocolate in Spain
Content:  The navigator Christopher Columbus, with the economic backing of the Catholic Monarchs, first reached the shores of the New World on 12 October 1492, initially believing that he had reached India. This voyage was carried out to expand markets by establishing new trade routes and therefore rival the Portuguese Empire, which was already well established in Asia. Following the success of that first voyage to the New World, others were organised with the intention of exploring and creating new trade routes. On his fourth voyage, Columbus, in 1502, met an unexpected storm and was forced to temporarily land on 15 August on the Bay Islands. In their first explorations of the area, Columbus' group came upon a boat of Mayan origin travelling from the Yucatán Peninsula. The Spaniards were surprised by the large size of the vessel. Columbus detained the vessel and examined the cargo, which 
Title: History of Cuba
Content:  Christopher Columbus, on his first Spanish-sponsored voyage to the Americas in 1492, sailed south from what is now the Bahamas to explore the northeast coast of Cuba and the northern coast of Hispaniola. Columbus, who was searching for a route to India, believed the island to be a peninsula of the Asian mainland. The first sighting of a Spanish ship approaching the island was on 27 October 1492, probably at Bariay, Holguín Province, on the eastern point of the island. During a second voyage in 1494, Columbus passed along the south coast of the island, landing at various inlets including what was to become Guantánamo

In 1473, Columbus began his apprenticeship as business agent for the wealthy Spinola, Centurione, and Di Negro families of Genoa. Later, he made a trip to Chios, an Aegean island then ruled by Genoa. In May 1476, he took part in an armed convoy sent by Genoa to carry valuable cargo to northern Europe. He probably docked in Bristol, England, and Galway, Ireland. He may have also gone to Iceland in 1477. It is known that in the autumn of 1477, he sailed on a Portuguese

The largest was a carrack, the Santa María, owned and captained by Juan de la Cosa, and under Columbus's direct command. The other two were smaller caravels, the Pinta and the Niña, piloted by the Pinzón brothers. Columbus first sailed to the Canary Islands. There he restocked provisions and made repairs then departed from San Sebastián de La Gomera on 6 September, for what turned out to be a five-week voyage across the ocean. On 7 October, the crew spotted "[i]mmense flocks of birds".
