The Gulag started to shrink soon after Joseph Stalin’s death in 1953. Hundreds of thousands of prisoners were amnestied from 1953 to 1957. The Gulag was officially disbanded, and its activities were grouped in 1955 under a new body, GUITK (Glavnoye Upravleniye Ispravitelno-Trudovykh Kolony, or “Chief Administration of Corrective Labour Colonies”).
