Tensions then grew even worse with the Bay of Pigs invasion in April of 1961, which was a failed attempt by Cuban exiles backed by the United States to overthrow Castro. This was important because the failed invasion strengthened Castro’s power inside Cuba and pushed him closer to the Soviet Union.
That closer Soviet relationship helped lead to the Cuban Missile Crisis in October of 1962. Castro allowed the Soviet Union to place nuclear missiles in Cuba, and the crisis became the closest the Cold War came to full-scale nuclear war. As such, Fidel Castro became one of the central figures in Cold War history, even though the main negotiations were carried out by Nikita Khrushchev and John F. Kennedy.
