Polish Workers' Party
In 1944 the ZPP formally recognized the State National Council ("Krajowa Rada Narodowa", KRN) established in Warsaw by the ZPP's rival communist institution, the Polish Workers' Party (PPR). Together with the PPR and the Soviets, the ZPP was responsible for the formation in July 1944 of the Polish Committee of National Liberation ("Polski Komitet Wyzwolenia Narodowego", PKWN), a nascent communist government; it included ZPP members.
