Shortly after his death, the Soviet Union went through a period of de-Stalinization. Malenkov denounced the Stalin personality cult, which was subsequently criticised in "Pravda". In 1956, Khrushchev gave his "Secret Speech", titled "On the Cult of Personality and Its Consequences", to a closed session of the Party's 20th Congress. There, Khrushchev denounced Stalin for both his mass repression and his personality cult. He repeated these denunciations at the 22nd Party Congress in October 1962. In October 1961, Stalin's body was removed from the mausoleum and buried in the Kremlin Wall Necropolis next to the Kremlin walls, the location marked only by a simple bust. Stalingrad was renamed Volgograd.
