Nikita Sergeyevich Khrushchev was the First Secretary of the Communist Party of the Soviet Union from 1953 to 1964 and the Chairman of the Council of Ministers from 1958 to 1964. As leader of the Soviet Union, he shocked the world by denouncing his predecessor Joseph Stalin, embarking on a campaign of de-Stalinization, and presiding over the Cuban Missile Crisis in 1962. In 1957, Khrushchev consolidated his leadership of the Soviet Union, surviving a plot to dismiss him by Stalinist members within the Presidium, and leading the Soviet Union into the Space Race with the launch of Sputnik 1.
