Khrushchev era

In the USSR, the eleven-year period from the death of Joseph Stalin (1953) to the political ouster of Nikita Khrushchev (1964), the national politics were dominated by the Cold War; the ideological U.S.–USSR struggle for the planetary domination of their respective socio–economic systems, and the defense of hegemonic spheres of influence. Nonetheless, since the mid-1950s, despite the Communist Party of the Soviet Union (CPSU) having disowned Stalinism, the political culture of Stalinism—an omnipotent General Secretary, anti-Trotskyism, a five-year planned economy (post-New Economic Policy), and repudiation of the Molotov–Ribbentrop Pact secret protocols—remained the character of Soviet society until the accession of Mikhail Gorbachev as leader of the CPSU in 1985.

After Stalin died in March 1953, he was succeeded by Nikita Khrushchev as First Secretary of the Central Committee of the Communist Party of the Soviet Union (CPSU) and Georgi Malenkov as Premier of the Soviet Union. However the central figure in the immediate post-Stalin period was the former head of the state security apparatus, Lavrentiy Beria.
