The Constitution of the Polish People's Republic (also known as July Constitution or Constitution of 1952) was passed on 22 July 1952. Created by the Polish communists in the Polish People's Republic, it was based on the 1936 Soviet Constitution (also known as Stalin Constitution), and it superseded the post-war provisional Small Constitution of 1947 which, in its turn, had declared null and void the pre-war April Constitution, defined as fascist. The Russian text of the Constitution was reviewed and corrected by Soviet premier Joseph Stalin and later translated into Polish. It legalized the communist legislature and practices as they had been introduced to Poland with the Polish Committee of National Liberation in the wake of Red Army progress in 1944.
