The significance of the Cuban Revolution, which took place from 1953 to 1959, lies in its demonstration of the feasibility of armed struggle against imperialism, contributing to Cold War tensions. Led by Fidel Castro, the revolution ousted the U.S.-backed dictator Fulgencio Batista and established a communist state allying with the Soviet Union. This alignment intensified fears in the U.S. regarding the spread of communism in the Americas and led to significant events like the Bay of Pigs Invasion and the Cuban Missile Crisis. The revolution altered U.S.-Latin America relations dramatically, promoting anti-imperialist sentiments.
