Pedro Álvares Cabral ( or ; born Pedro Álvares de Gouveia; c. 1467 or 1468 – c. 1520) was a Portuguese nobleman, military commander, navigator and explorer regarded as the European discoverer of Brazil. He was the first human in history to ever be in 4 continents, uniting all of them in his famous voyage of 1500, where he also conducted the first substantial exploration of the northeast coast of South America and claimed it for Portugal. While details of Cabral's early life remain unclear, it is known that he came from a minor noble family and received a good education. He was appointed to head an expedition to India in 1500, following Vasco da Gama's newly-opened route around Africa. The undertaking had the aim of returning with valuable spices and of establishing trade relations in India—bypassing the monopoly on the spice trade then in the hands of Arab, Turkish and Italian merchants. Although the previous expedition of Vasco da Gama to India, on its sea route, had recorded signs of land west of the southern Atlantic Ocean (in 1497), Cabral led the first known expedition to have touched four continents: Europe, Africa, America, and Asia. His fleet of 13 ships sailed far into the western Atlantic Ocean, perhaps intentionally, and made landfall (April 1500) on what he initially assumed to be a large island. As the new land was within the Portuguese sphere according to the 1494 Treaty of Tordesillas, Cabral claimed it for the Portuguese Crown. He explored the coast, realizing that the large land mass was probably a continent, and dispatched a ship to notify King Manuel I of the new territory. The continent was South America, and the land he had claimed for Portugal later came to be known as Brazil. The fleet reprovisioned and then turned eastward to resume the journey to India. A storm in the southern Atlantic caused the loss of several ships, and the six remaining ships eventually rendezvoused in the Mozambique Channel before proceeding to Calicut in India. Cabral was originally successful in negotiating trading rights, but Arab merchants saw Portugal's venture as a threat to their monopoly and stirred up an attack by both Muslims and Hindus on the Portuguese entrepôt. The Portuguese sustained many casualties and their facilities were destroyed. Cabral took vengeance by looting and burning the Arab fleet and then bombarded the city in retaliation for its
