Fidel Alejandro Castro Ruz was a Cuban revolutionary and politician who served as Prime Minister of Cuba from 1959 to 1976 and President from 1976 to 2008. Ideologically a Marxist-Leninist and Cuban nationalist, he also served as the First Secretary of the Communist Party of Cuba from 1961 until 2011. Under his administration the Republic of Cuba became a one-party communist state; industry and business were nationalized, and state socialist reforms were implemented throughout society.
Born in Birán, Oriente as the son of a wealthy Spanish farmer, Castro adopted leftist anti-imperialist ideas while studying law at the University of Havana. After participating in rebellions against right-wing governments in the Dominican Republic and Colombia, he planned the overthrow of Cuban President Fulgencio Batista, launching a failed attack on the Moncada Barracks in 1953. After a year's imprisonment, Castro traveled to Mexico where he formed a revolutionary group, the 26th of July Movement, with his brother Raúl Castro and Ernesto "Che" Guevara.
