The term "de-Stalinization" is one which gained currency in both Russia and the Western world following the collapse of the Soviet Union, but 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 Joseph 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.
