Cuban Revolution: Fidel Castro's 26th of July Movement, heavily reinforced by Frank Pais Militia, overwhelm an army post in El Uvero.

The Cuban Revolution was the military and political movement that overthrew the dictatorship of Fulgencio Batista, who had ruled Cuba from 1952 to 1959. The revolution began after the 1952 Cuban coup d'état, in which Batista overthrew the emerging Cuban democracy and consolidated power. Among those who opposed the coup was Fidel Castro, then a young lawyer, who initially tried to challenge the takeover through legal means in the Cuban courts. When these efforts failed, Fidel Castro and his brother Raúl led an armed assault on the Moncada Barracks, a Cuban military post, on 26 July 1953.

Fidel Alejandro Castro Ruz was a Cuban politician and revolutionary who was the leader of Cuba from 1959 to 2008, serving as the 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 1965 until 2011. Under his administration, Cuba became a one-party communist state; industry and business were nationalized, and socialist reforms were implemented throughout society.

The 26 July Movement was a Cuban vanguard revolutionary organization and later a political party led by Fidel Castro. The movement's name commemorates the failed 1953 attack on the Moncada Barracks in Santiago de Cuba, part of an attempt to overthrow the dictator Fulgencio Batista. M-26-7 is considered the leading organization of the Cuban Revolution.
