Censorship in the Polish People's Republic

Censorship in Communist Poland was primarily performed by the Polish Main Office of Control of Press, Publications and Shows (Główny Urząd Kontroli Prasy, Publikacji i Widowisk), a governmental institution created in 1946 by the pro-Soviet Provisional Government of National Unity with Stalin's approval and backing, and renamed in 1981 as the Główny Urząd Kontroli Publikacji i Widowisk (GUKPiW). The bureau was liquidated after the fall of communism in Poland, in April 1990.
