Polish Socialist Party in the context of "List of political parties in Poland"

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.

Parliamentary elections were held in Poland on 19 January 1947, the first since World War II. According to the official results, the Democratic Bloc (Blok Demokratyczny), dominated by the Polish Workers' Party (PPR) and also including the Polish Socialist Party (PPS), People's Party (SL), Democratic Party (SD), and non-partisan candidates officially received 80% of the vote and 394 of the 444 seats in the Legislative Sejm. The largest opposition party, the Polish People's Party, was officially credited with 28 seats; however, the elections were characterized by violence; anti-Communist opposition candidates and activists were persecuted by the Volunteer Reserve Militia (ORMO).

The elections were heavily manipulated, and the opposition claimed that it would have won in a landslide had the election been conducted in a fair manner. The election gave the Soviets, as well as the Communist-dominated Polish satellite government, enough legitimacy to claim that Poland was "free and democratic", thus allowing Poland to sign the charter of the United Nations.

The Polish Workers' Party (Polish: Polska Partia Robotnicza, PPR) was a communist party in Poland from 1942 to 1948. It was founded as a reconstitution of the Communist Party of Poland (KPP) and merged with the Polish Socialist Party (PPS) in 1948 to form the Polish United Workers' Party (PZPR). From the end of World War II the PPR led Poland, with the Soviet Union exercising moderate influence. During the PPR years, the centers of opposition activity were largely diminished, and a socialist system was established in the country.

Arriving from the Soviet Union, a group of Polish communists was parachuted into occupied Poland in December 1941. With Joseph Stalin's permission, in January 1942 they established the Polish Workers' Party, a new communist party. The PPR established a partisan military organization Gwardia Ludowa, later renamed Armia Ludowa. In November 1943, Władysław Gomułka became secretary (chief executive) of the Central Committee of the PPR. On 1 January 1944 the party created the State National Council (KRN), proclaimed to be a wartime parliament of Poland; the body was chaired by Bolesław Bierut. In June 1944 the Union of Polish Patriots, a rival to the PPR Polish-communist organization operating in the Soviet Union, recognized the KRN as "the true representation of the Polish nation". The PPR was initially a small party with marginal support; it grew because of its alliance with the victorious Soviet Union.

Bolesław Bierut ([bɔˈlɛswaf ˈbʲɛrut] ; 18 April 1892 – 12 March 1956) was a Polish communist activist and politician, leader of communist-ruled Poland from 1948 until 1956. He was President of the State National Council from 1944 to 1947, President of Poland from 1947 to 1952, General Secretary of the Central Committee of the Polish United Workers' Party from 1948 to 1956, and Prime Minister of Poland from 1952 to 1954. Bierut is believed to have worked as an NKVD informant or agent prior to 1945, although his relationship with the Soviet agency has been a subject of debate among historians. As communist leader, he implemented aspects of the Stalinist system in Poland. Together with Władysław Gomułka, his main rival, Bierut is chiefly responsible for the historic changes that Poland underwent in the aftermath of World War II. Unlike any of his communist successors, Bierut led Poland until his death.

Born in Congress Poland on the outskirts of Lublin, Bierut joined the Polish Socialist Party in 1912. Later he became a member of the Communist Party of Poland and spent some years in the Soviet Union. He was sentenced to a prison term in 1935 for conducting illegal labor activity in Poland by the anti-communist Sanation government and was later released in 1938. During World War II, Bierut was an activist of the newly founded Polish Workers' Party (PPR) and subsequently the chairman of the State National Council (KRN), established by the PPR. Trusted by Joseph Stalin, Bierut participated in the Potsdam Conference, where he successfully lobbied for the establishment of Poland's western border at the Oder–Neisse line.

Józef Klemens Piłsudski (Polish: [ˈjuzɛf ˈklɛmɛns piwˈsutskʲi] ; 5 December 1867 – 12 May 1935) was a Polish statesman who served as the Chief of State (1918–1922) and first Marshal of Poland (from 1920). In the aftermath of World War I, he became an increasingly dominant figure in Polish politics and exerted significant influence on shaping the country's foreign policy. Piłsudski is viewed as a father of the Second Polish Republic, which was re-established in 1918, 123 years after the final partition of Poland in 1795, and was considered de facto leader (1926–1935) of the Second Republic as the Minister of Military Affairs.

Seeing himself as a descendant of the culture and traditions of the Polish–Lithuanian Commonwealth, Piłsudski believed in a multi-ethnic Poland—"a home of nations" including indigenous ethnic and religious minorities to be assimilated as Poles. Early in his political career, Piłsudski became a leader of the Polish Socialist Party. Believing Poland's independence would be won militarily, he formed the Polish Legions. In 1914, he predicted a new major war would defeat the Russian Empire and the Central Powers. After World War I began in 1914, Piłsudski's Legions fought alongside Austria-Hungary against Russia. In 1917, with Russia faring poorly in the war, he withdrew his support for the Central Powers, and was imprisoned in Magdeburg by the Germans.

The Politburo was the highest political organ of the Central Committee of the Polish United Workers' Party, which existed from 1948 to 1990. The Politburo typically had between 9 and 15 members at any one time. Usually, several alternates (or candidates) were also elected to the Politburo, but unlike members, alternates did not possess voting rights.

The predecessor of the PUWP was the Polish Workers' Party (Polska Partia Robotnicza). In 1948, it merged with the Polish Socialist Party to form the PUWP. A chronological list of Politburo membership is provided below.

Tomasz Stefan Arciszewski (Polish pronunciation: [ˈtɔmaʂ art͡ɕiˈʂɛfskʲi]; 4 November 1877 – 20 November 1955) was a Polish socialist politician, a member of the Polish Socialist Party and the 31st Prime Minister of Poland, 3rd Prime Minister of the Polish government-in-exile in London from 1944 to 1947 during which the government lost the recognition of the Western powers.
