The Gulag was a system of forced labor camps in the Soviet Union. The word Gulag originally referred only to the division of the Soviet secret police that was in charge of running the forced labor camps from the 1930s to the early 1950s during Joseph Stalin's rule, but in English literature the term is popularly used for the system of forced labor throughout the Soviet era. The abbreviation GULAG (ГУЛАГ) stands for "Гла́вное Управле́ние исправи́тельно-трудовы́х ЛАГере́й", but the full official name of the agency changed several times.

The All-Russian Extraordinary Commission, abbreviated as VChK, and commonly known as Cheka, was the first of a succession of Soviet secret-police organizations known for conducting the Red Terror. Established on December 5 1917 by the Sovnarkom, it came under the leadership of Bolshevik revolutionary Felix Dzerzhinsky. By late 1918, hundreds of Cheka committees had sprung up in the Russian SFSR at all levels.
