Christopher Columbus was borm in Genoa, Italy in 1451 He worked with his father as a weaver, but the sea was alwways his real passion. In the 15th century, it was difficult and dangerous to travel to Asia around the southerm tip of Africa. Columbus decided to try to sail west to find a new trade route. People made fun of him, but finally King Ferdinand and Queen Isabella of Spain gave him supplies, men and three sailing ships for his voyage. They wanted to find a way to import gold and spices from Asia. Columbus set sail from Spain in August 1492 with his three ships the Niña, the Pinta and the Santa María. Ten weeks later, he reached an island in the Bahamas. As he thought he was in India, he called the people there Indians! On the voyage home, Columbus lost th Santa María in a terrible storm. He arrived safely back in Sain in March 1493, with plants, gold, cloth, ornaments, and other riches. Columbus made three more voyages to 'the New World'. He explored the coasts of Cuba, Hispaniola (modern-day Haiti and the Dominican Republic), Venezuela and Central America. On each voyage, he believed he was in Indial He died in 1506 without knowing the importance of what he found on his voyages.
