De-Stalinization (Russian: десталинизация, Destalinizatsiya) consisted of a series of political reforms in the Soviet Union after the death of long-time leader Joseph Stalin in 1953, and the ascension of Nikita Khrushchev to power.
The reforms consisted of changing or removing key institutions that helped Stalin hold power: the cult of personality that surrounded him, the Stalinist political system, and the Gulag labour-camp system, all of which had been created and dominated by him. Stalin was succeeded by a collective leadership after his death in March 1953, consisting of Georgi Malenkov, Premier of the Soviet Union; Lavrentiy Beria, head of the Ministry of the Interior; and Nikita Khrushchev, First Secretary of the Central Committee of the Communist Party of the Soviet Union (CPSU).
The term "de-Stalinization" is a term which gained currency in both Russia and the Western world following the collapse of the Soviet Union, and was never used during the Khrushchev era. However, de-Stalinization efforts were set forth at this time by Nikita Khrushchev and the Government of the Soviet Union under the guise of the "overcoming/exposure of the cult of personality", with a heavy criticism of the Josef Stalin's "era of the cult of personality". However, prior to Khrushchev's "Secret Speech" to the 20th Party Congress, no direct association between Stalin as a person and "the cult of personality" was openly made by Khrushchev or others within the party, although archival documents show that strong criticism of Stalin and his ideology featured in private discussions by Khruschchev at the Presidium of the Supreme Soviet.
