De-Stalinization (Russian: десталинизация) refers to a process of political reform in the USSR that took place after the death of its de facto leader Josef Stalin in 1953. 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 the him as General Secretary of the Central Committee of the Communist Party of the Soviet Union, among other titles, from 1922–52. Stalin was succeeded by a collective leadership after his death in March 1953, consisting of: Lavrentiy Beria, head of the Ministry of the Interior; Nikita Khrushchev, First Secretary of the Central Committee of the Communist Party of the Soviet Union (CPSU); and Georgi Malenkov, Premier of the Soviet Union. Contemporary historians regard the process of de-Stalinization as a significant turning point in the history of modern Russia.
Beginnings: Khrushchev's Speech
De-Stalinization meant an end to the role of large-scale forced labour in the economy, although the Gulag was not closed. The process of freeing Gulag prisoners was started by Beria, but he was soon removed from power. In turn, Khrushchev then emerged as the most powerful Soviet politician.
Many argue that the watershed moment of de-Stalinization was when Khrushchev gave a speech entitled, "On the Personality Cult and its Consequences," concerning Stalin. On 25 February 1956, he spoke to a closed session of the Twentieth Party Congress of the Communist Party of the Soviet Union. Khrushchev thoroughly shocked his listeners by denouncing Stalin's dictatorial rule and his cult of personality as inconsistent with Communist and Party ideology. Among other points, he condemned the treatment of the Old Bolsheviks, people who had supported communism before the revolution, many of whom Stalin had executed as traitors. Khrushchev also attacked the crimes committed by associates of Lavrentiy Beria.
Improved prison conditions
Khrushchev also attempted to lessen the harshness of the Gulag labour system, by allowing prisoners to send letters home to their families, and by allowing family members to mail clothes to loved-ones in the camps, which was not allowed during Stalin's time. Furthermore, when Stalin died, the Gulag was "radically reduced in size."  Even though Khrushchev and others with reformist ideals wanted to lessen the scale of the Gulag, it continued to exist until 1987 when Gorbachev "dissolve[d] the Soviet Union’s political camps altogether." 
Re-naming of places
As part of the de-Stalinization push, Khrushchev endeavored to have many places bearing Stalin's name renamed or reverted to their former names, including cities, landmarks, and other facilities. These included even capital cities of the Soviet republics and territories: in 1961, Stalinabad, capital of the Tajik SSR, was renamed Dushanbe, and Staliniri, capital of the South Ossetian Autonomous Oblast, was renamed Tskhinvali
In a broadly symbolic gesture, National Anthem of the Soviet Union was purged of references to Stalin. The Stalin-centric and World War II-era lines in the lyrics were effectively excised when an instrumental version replaced it.
Re-location of Stalin's body
Given momentum by these public renamings, the process of de-Stalinization peaked in 1961 during the 22nd Congress of the CPSU. Two climactic acts of de-Stalinization marked the meetings: first, on October 31, 1961, Stalin's body was moved from Lenin's Mausoleum in Red Square to a location near the Kremlin wall; second, on November 11, 1961, the "hero city" Stalingrad was renamed Volgograd.
