The significance of the Cuban Revolution, which culminated in 1959, lies in its profound political, social, and economic impact on Cuba and beyond. Led by Fidel Castro and Che Guevara, the revolution replaced the U.S.-backed dictator Fulgencio Batista with a socialist government. It established Cuba as a one-party state, implemented land reforms, and significantly shifted the country’s relationship with the United States, leading to the Cold War tensions, exemplified by events like the Bay of Pigs Invasion and the Cuban Missile Crisis.
