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. The Communist Party, now headed by Castro's brother Raúl, continues to govern Cuba today.The Cuban Revolution had powerful domestic and international repercussions. In particular, it reshaped Cuba's relationship with the United States, which continues an embargo against Cuba as of 2015, although efforts to improve diplomatic relations have gained momentum in recent years. In the immediate aftermath of the revolution, Castro's government began a program of nationalization and political consolidation that transformed Cuba's economy and civil society. The revolution also heralded an era of Cuban intervention into foreign military conflicts, including the Angolan Civil War and Nicaraguan Revolution.
