The Main Administration for Affairs of Prisoners of War and Internees[note 1] (Russian: Главное управление по делам военнопленных и интернированных НКВД/МВД СССР, ГУПВИ, romanized: GUPVI, GUPVI NKVD SSSR/ MVD SSSR) was an NKVD (later MVD) department in charge of handling of foreign civilian internees and prisoners of war (POWs) in the Soviet Union during and in the aftermath of World War II (1939–1953).
GUPVI was established as a part of the NKVD under the name "Administration for Affairs of Prisoners of War and Internees (UPVI) in September 1939, after the Soviet invasion of Poland.
The legal foundation for its creation was the Sovnarkom Decree of July 1, 1941 "Regulations on Prisoners of War" ("Положение о военнопленных"), updated by the September 29, 1945 "Regulations on Use of Labor of Prisoners of War" (Положение о трудовом использовании военнопленных).
[7][8][9] Significant efforts were made to "ideologically reforge" (идеологическая перековка) prisoners, and numerous clubs, libraries and local radio stations were created.
