Nikita Khrushchev becomes the first Soviet leader to visit the United States.

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 (premier) from 1958 to 1964. As leader, he stunned the communist world by denouncing his predecessor Joseph Stalin and launching a campaign of de-Stalinization, and presided over the Cuban Missile Crisis in 1962.

The Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union, was a transcontinental country that spanned much of Eurasia from 1922 until it dissolved in 1991. During its existence, it was the largest country by area, extending across eleven time zones and sharing borders with twelve countries, and the third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of national republics, the largest and most populous of which was the Russian SFSR. In practice, its government and economy were highly centralized. As a one-party state governed by the Communist Party of the Soviet Union (CPSU), it was the flagship communist state. Its capital and largest city was Moscow.
