Union of Polish Patriots (Society of Polish Patriots, Polish: Związek Patriotów Polskich, ZPP, Russian: Союз Польских Патриотов, СПП) was a political body created by Polish communists in the Soviet Union in 1943. The ZPP, unofficially controlled and directed by Joseph Stalin, became one of the founding structures of the Soviet-controlled communist government that after World War II took power in Poland.
The ZPP was a mass organization with about 100,000 members (Polish citizens in the Soviet Union, mostly war refugees and Soviet deportees left after the departure of Anders' Army). It was dominated by former members of the Communist Party of Poland, in particular people from the Central Bureau Communists of Poland, which was established after the ZPP and also operated in the Soviet Union. The ZPP included activists of many political orientations. During World War II, there were about 1,500 declared Polish communists in the Soviet Union.
