The 26th of July Movement (Spanish: Movimiento 26 de Julio; M-26-7) was a Cuban vanguard revolutionary organization and later a political party led by Fidel Castro. The movement's name commemorates its 26 July 1953 attack on the army barracks on Santiago de Cuba in an attempt to start the overthrowing of the dictator Fulgencio Batista.This is considered one of the most important organizations among the Cuban Revolution. At the end of 1956, Castro established a guerrilla base in the Sierra Maestra. This base defeated the troops of Batista on 31 December 1958, setting into motion the Cuban Revolution and installing a government led by Manuel Urrutia Lle. The Movement fought the Batista regime on both rural and urban fronts. The movement's main objectives were distribution of land to peasants, nationalization of public services, industrialization, honest elections, and large scale education reform.

In July 1961, the 26th of July Movement was one of the parties that integrated into the Integrated Revolutionary Organization (ORI) as well as the Popular Socialist Party (PSP) and the 13 March Revolutionary Directorate. On 26 March 1962, the party dissolved to form the United Party of the Cuban Socialist Revolution (PURSC), which held a communist ideology.



The Cuban Revolution (Spanish: Revolución cubana) was an armed revolt conducted by Fidel Castro and his fellow revolutionaries of the 26th of July Movement and its allies against the military dictatorship of Cuban President Fulgencio Batista. The revolution began in July 1953, and continued sporadically until the rebels finally ousted Batista on 31 December 1958, replacing his government. 26 July 1953 is celebrated in Cuba as Día de la Revolución (from Spanish: "Day of the Revolution"). The 26th of July Movement later reformed along Marxist–Leninist lines, becoming the Communist Party of Cuba in October 1965.The Cuban Revolution had powerful domestic and international repercussions. In particular, it transformed Cuba–United States relations, although efforts to improve diplomatic relations, such as the Cuban thaw, gained momentum during the 2010s. In the immediate aftermath of the revolution, Castro's government began a program of nationalization, centralization of the press and political consolidation that transformed Cuba's economy and civil society. The revolution also heralded an era of Cuban medical internationalism and Cuban intervention in foreign conflicts in Africa, Latin America, Southeast Asia, and the Middle East. Several rebellions occurred in the six years following 1959, mainly in the Escambray Mountains, which were defeated by the revolutionary government.
