Khrushchev Thaw in the context of "Soviet political repressions"

Stalinism is the means of governing and Marxist–Leninist policies implemented in the Soviet Union (USSR) from 1927 to 1953 by Joseph Stalin. It included the creation of a one-party totalitarian police state, rapid industrialization, the theory of socialism in one country (until 1939), collectivization of agriculture, intensification of class conflict, a cult of personality, and subordination of the interests of foreign communist parties to those of the Communist Party of the Soviet Union, deemed by Stalinism to be the leading vanguard party of communist revolution at the time. After Stalin's death and the Khrushchev Thaw, a period of de-Stalinization began in the 1950s and 1960s, which caused the influence of Stalin's ideology to begin to wane in the USSR.

Stalin's regime forcibly purged society of what it saw as threats to itself and its brand of communism (so-called "enemies of the people"), which included political dissidents, non-Soviet nationalists, the bourgeoisie, better-off peasants ("kulaks"), and those of the working class who demonstrated "counter-revolutionary" sympathies. This resulted in mass repression of such people and their families, including mass arrests, show trials, executions, and imprisonment in forced labour camps known as gulags. The most notorious examples were the Great Purge and the Dekulakization campaign. Stalinism was also marked by militant atheism, mass anti-religious persecution, and ethnic cleansing through forced deportations. However, there was a short era of reconciliation between the Orthodox Church and the state authorities in WW2. Some historians, such as Robert Service, have blamed Stalinist policies, particularly the collectivization policies, for causing famines such as the Holodomor. Other historians and scholars disagree on the role of Stalinism.

The Great Terror: Stalin's Purge of the Thirties is a book by British historian Robert Conquest which was published in 1968. It gave rise to an alternate title of the period in Soviet history known as the Great Purge. Conquest's title was also an allusion to the period that was called the Reign of Terror during the French Revolution (French: la Terreur and from June to July 1794 la Grande Terreur, "the Great Terror"). A revised version of the book, called The Great Terror: A Reassessment, was printed in 1990 after Conquest was able to amend the text, having consulted the opened Soviet archives. The book was funded and widely disseminated by Information Research Department, who also published Orwell's list collected by Conquest's secretary Celia Kirwan.

One of the first books by a Western writer to discuss the Great Purge in the Soviet Union, it was based mainly on information which had been made public, either officially or by individuals, during the Khrushchev Thaw in the period 1956–1964, and on an analysis of official documents such as the Soviet census. It also drew on accounts by Russian and Ukrainian émigrés and exiles dating back to the 1930s. The book was well received in the popular press but its estimates started a debate among historians. Conquest defended his higher estimates of 20 million, which are supported by some historians and other authors in the popular press, while other historians said that even his reassessments were still too high and are considerably less than originally thought.

De-Stalinization (Russian: десталинизация, romanized: destalinizatsiya) comprised a series of political reforms in the Soviet Union after the death of long-time leader Joseph Stalin in 1953, and the thaw brought about by ascension of Nikita Khrushchev to power, and his 1956 secret speech "On the Cult of Personality and Its Consequences", which denounced Stalin's cult of personality and the Stalinist political system.

Monuments to Stalin were removed, his name was removed from places, buildings, and the state anthem, and his body was removed from the Lenin Mausoleum (known as the Lenin and Stalin Mausoleum from 1953 to 1961) and buried. These reforms were started by the collective leadership which succeeded him after his death on 5 March 1953, comprising 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).

Anti-revisionism is a position within Marxism–Leninism which emerged in the mid-1950s in opposition to the reforms of Soviet leader Nikita Khrushchev.

Caucasus Germans (German: Kaukasiendeutsche) are part of the German minority in Russia and the Soviet Union. They migrated to the Caucasus largely in the first half of the 19th century and settled in the North Caucasus, Georgia, Azerbaijan, Armenia and the region of Kars (present-day northeastern Turkey). In 1941, the majority of them were subject to deportation to Central Asia and Siberia during Joseph Stalin's population transfer in the Soviet Union. After Stalin's death in 1953 and the beginning of the Khrushchev Thaw, the Caucasus Germans were allowed to return, though only few did. Many assimilated and, after 1991, immigrated to Germany. Although the community today is a fraction of what it once was, many German buildings and churches are still extant, with some turned into museums.
