Cuba was a playground for rich and wealthy Americans after the Platt Amendment. The Platt Amendment established that the United States would remove its military from Cuba and leave it to govern itself.
This struck a need for change in a young lawyer named Fidel Castro (right). He believed President Batista was a tyrant and he wanted legal change, but he failed at this.
Castro then started a movement called Viva Revolution to overthrow Batista and make him flee Havana. He then instills himself as the new leader of Cuba. At first he seemed to be a socialist leader, but as time went on a problem occurred.
It became obvious to the leaders of the United States that Castro started having more communist ideologies. This brought fear to the people of the U.S. because communism was spreading and was right at their doorstep. The C.I.A. decided to create a plan to stop this.
They trained Cuban Nationalist Refugees to revolt against Castro in an event called the Bay of Pigs Invasion. This would be a revolt set up by the United States and could potentially allow the U.S. to put in a new leader of Cuba.
Unfortunately, the invasion turned out to be a complete disaster. It ended up being a huge embarrassment for America an did the exact opposite of what it was supposed to do. The invasion brought Castro closer to communism and allowed him to ally with Nikita Khrushchev.
