Polish United Workers' Party

The Polish United Workers' Party (Polish: Polska Zjednoczona Partia Robotnicza [ˈpɔlska zjɛdnɔˈt͡ʂɔna ˈpartja rɔbɔtˈɲit͡ʂa], PZPR) was the communist party which ruled the Polish People's Republic as a one-party state from 1948 to 1989. The PZPR had led two other legally permitted subordinate minor parties together as the Front of National Unity and later Patriotic Movement for National Rebirth. The Polish United Workers' Party had total control over public institutions in the country as well as the Polish People's Army, the UB and SB security agencies, the Citizens' Militia (MO) police force and the media.

The falsified 1947 Polish legislative election granted the Communist Polish Workers' Party (PPR) complete political authority in post-war Poland. The PZPR was founded forthwith in December 1948 through the unification of the PPR and the Polish Socialist Party (PPS). From 1952 onward, the position of "First Secretary" of the Polish United Workers' Party was de facto equivalent to Poland's head of state. Throughout its existence, the PZPR maintained close ties with ideologically similar parties of the Eastern Bloc, most notably the Socialist Unity Party of Germany, Communist Party of Czechoslovakia and the Communist Party of the Soviet Union. Between 1948 and 1954, nearly 1.5 million individuals registered as Polish United Workers' Party members, and membership rose to 3 million by 1980.
