What was the Bay of Pigs Invasion?

The Bay of Pigs Invasion was a covert attempt by the United States to take the socialist Cuban dictator, Fidel Castro, out of power. The United States secretly funded and supported exiled Cuban revolutionaries who opposed Castro's regime to invade Cuba and take control of the government. These revolutionaries were defeated by Castro's military after the U.S. withdrew air support. The Bay of Pigs Invasion was a failure for the United States, and it further strained U.S. relations with Cuba and the Soviet Union during the Cold War.

When did Bay of Pigs Happen?

Following World War II, the relationship between the United States and the communist Soviet Union deteriorated quickly, and the nations of the world divided between the two sides. Both the United States and Soviet Union engaged in "proxy wars" in which the U.S. and USSR funded governments and militaries that supported either capitalism or communism. However, neither country wanted to ignite full blown war between the two nuclear superpowers. This standoff between the U.S. and the USSR and their allies became known as the Cold War, and countries around the world were divided between capitalism and communism. In 1958, Fidel Castro successfully led an armed coup against the pro-American government and established a socialist regime in the country of Cuba. Castro severed ties with the United States and formed an alliance with the Soviet Union. This alliance concerned U.S. President Dwight D. Eisenhower, who ordered the Central Intelligence Agency (CIA) to make a plan to overthrow Castro. In 1960, the CIA began recruiting and training Cuban exiles who opposed Castro. When President John F. Kennedy came to office, he was told of this plan, then known as "Operation Zapata". Kennedy approved that invasion and on April 17, 1961 the United States and former Cuban exiles landed in Cuba to fight against Castro's regime.

Why Did the Bay of Pigs Happen?

The Bay of Pigs Invasion was a small episode in the larger Cold War era between the United States and the Soviet Union. When Fidel Castro established his socialist regime in Cuba, the United States viewed Castro as an immediate threat to the United States. When Castro showed allegiance to the USSR and communism, the United States believed the only way to protect their interests was with direct involvement in Cuba's government. President John F. Kennedy ordered the Bay of Pigs Invasion in April 1961 to prevent the spread of communism in the western world.
