Cuban Revolution
The Cuban Revolution (Spanish: Revolución cubana) was the military and political effort to overthrow Fulgencio Batista 's dictatorship which reigned as the government of Cuba between 1952 and 1959. It began after the 1952 Cuban coup d'état which saw former president and military general, Fulgencio Batista topple the nascent Cuban democracy and consolidate power. Among those opposing the coup was Fidel Castro, then a novice attorney who attempted to contest the coup through Cuba's judiciary. Once these efforts proved fruitless, Fidel Castro and his brother Raúl led an armed attack on the Cuban military's Moncada Barracks on 26 July 1953. Following the attack's failure, Fidel Castro and his co-conspirators were arrested and formed the 26th of July Movement (M-26-7) in detention. At his trial, Fidel Castro launched into a two hour speech that won him national fame as he laid out his grievances against the Batista dictatorship. In an attempt to win public approval, Batista granted amnesty to the surviving Moncada Barracks attackers and the Castros fled into exile. During their exile, the Castros consolidated their strategy in Mexico and subsequently reentered Cuba in 1956, accompanied by Che Guevara, whom they had encountered during their time in Mexico.

Returning to Cuba aboard the Granma, the Castros, Guevara, and other supporters encountered gunfire from Batista's troops. The rebels fled to the Sierra Maestra where the M-26-7 rebel forces would reorganize, conducting urban sabotage and covert recruitment. Over time the Popular Socialist Party, once the largest and most powerful organizations opposing Batista, would see its influence and power wane towards the 26th of July Movement. As the irregular war against Batista escalated, the rebel forces transformed from crude, guerrilla fighters into a cohesive, fighting force that could confront Batista's army in military engagements. By the time the rebels were able to oust Batista, the revolution was being driven by a coalition between the Popular Socialist Party, 26th of July Movement, and the Revolutionary Directorate of 13 March.

The rebels, led by the 26th of July Movement finally toppled Batista on 31 December 1958, who fled the country. Batista's government was dismantled as Fidel Castro became the most prominent leader of the forces opposing Batista. Soon thereafter, the 26th of July Movement established itself as the de facto government. Although Castro was immensely popular in the period immediately following Batista's ouster, he quickly consolidated power leading to domestic and international tensions. 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 and profound 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 and have continued through the 2020s. 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, that angered both sectors of the Cuban population and the American government. In the aftermath of the revolution, Castro's authoritarianism in conjunction with the struggling economy lead to the Cuban Exodus as Cubans fled the island with the majority arriving in the United States. The revolution also heralded an era of Cuban intervention in foreign conflicts in Africa, Latin America, Southeast Asia, and the Middle East. Several rebellions occurred between 1959 and 1965, mainly in the Escambray Mountains, which were suppressed by the revolutionary government.
