Manuel I (European Portuguese: [mɐnuˈɛl]; 31 May 1469 – 13 December 1521), known as the Fortunate (Portuguese: O Venturoso), was King of Portugal from 1495 to 1521. A member of the House of Aviz, Manuel was Duke of Beja and Viseu prior to succeeding his cousin, John II of Portugal, as monarch. Manuel ruled over a period of intensive expansion of the Portuguese Empire owing to the numerous Portuguese discoveries made during his reign. His sponsorship of Vasco da Gama led to the Portuguese discovery of the sea route to India in 1498, resulting in the creation of the Portuguese India Armadas, which guaranteed Portugal's monopoly on the spice trade. Manuel began the Portuguese colonization of the Americas and Portuguese India, and oversaw the establishment of a vast trade empire across Africa and Asia.
Manuel established the Casa da Índia, a royal institution that managed Portugal's monopolies and its imperial expansion. He financed numerous famed Portuguese navigators, including Pedro Álvares Cabral (who discovered Brazil), Afonso de Albuquerque (who established Portuguese hegemony in the Indian Ocean), among numerous others. The income from Portuguese trade monopolies and colonized lands made Manuel the wealthiest monarch in Europe, allowing him to be one of the great patrons of the Portuguese Renaissance, which produced many significant artistic and literary achievements. Manuel patronized numerous Portuguese intellectuals, including playwright Gil Vicente (called the father of Portuguese and Spanish theatre). The Manueline style, considered Portugal's national architecture, is named for the king.
Manuel was born in Alcochete on 31 May 1469, the ninth child of Ferdinand, Duke of Viseu and Beatriz of Portugal. His father, Ferdinand, was the son of Edward, King of Portugal and the brother of Afonso V of Portugal, while his mother, Beatriz, was granddaughter of King John I of Portugal. In addition, his sister Eleanor of Viseu was the wife of King John II of Portugal.
Manuel grew up amidst strife between the Portuguese noble families and King John II. In 1483, Fernando II, Duke of Braganza, leader of Portugal's most powerful feudal house, was executed for treason. Later, Manuel's older brother, Diogo, Duke of Viseu, was accused of leading a conspiracy against the crown and was stabbed to death in 1484 by the king himself.
After the death of his son Prince Afonso and failed attempts to legitimise his illegitimate son, Jorge de Lencastre, Duke of Coimbra, John II named Manuel heir to the throne. Manuel succeeded John as king of Portugal in 1495.
Manuel would prove a worthy successor to his cousin John II for his support of Portuguese exploration of the Atlantic Ocean and development of Portuguese commerce. During his reign, the following achievements were realised:
1498 – The discovery of a maritime route to India by Vasco da Gama.
1500 – The voyage to Brazil by Pedro Álvares Cabral.
