The impact of the Cuban Revolution in 1959 on U.S.-Cuban relations was profound and enduring. The revolution, led by Fidel Castro, resulted in the overthrow of Fulgencio Batista’s regime and the establishment of a socialist government aligned with the Soviet Union. This shift alarmed the United States, leading to severed diplomatic ties and a range of actions aimed at undermining Castro’s government, including the Bay of Pigs invasion and the Cuban Missile Crisis. The revolution heightened Cold War tensions in the region, fostering an enduring economic and ideological divide, and affecting U.S. foreign policy in Latin America for decades thereafter.
