The Cuban Revolution (1953–1959) was an armed revolt conducted by Fidel Castro's 26th of July Movement and its allies against the U.S.-backed authoritarian government of Cuban President Fulgencio Batista. The revolution began in July 1953, and continued sporadically until the rebels finally ousted Batista on 1 January 1959, replacing his government with a revolutionary socialist state. The Movement organization later reformed along communist lines, becoming the Communist Party in October 1965.
