Stalin's personality cult, dictatorship and crimes were denounced in a secret speech by Nikita Khrushchev at the 20th Congress of the Communist Party of the Soviet Union in 1956. After it was decided at the 22nd Congress of the Communist Party of the Soviet Union in 1961 to remove Stalin's remains from Lenin's Mausoleum on Moscow's Red Square and to rename several cities which had been named after him, the Soviet government reburied the dictator's corpse in the Kremlin Wall Necropolis, honoring it with a marble bust.
