Polish United Workers' Party in the context of "Communist Party of the Soviet Union"

The revolutions of 1989, also known as the fall of communism, were a wave of liberal democratic movements that resulted in the collapse of most Marxist–Leninist governments in the Eastern Bloc and other parts of the world. This wave is sometimes referred to as the "autumn of nations", in reference to the revolutions of 1848 as the "spring of nations". The revolutions of 1989 were a key factor in the dissolution of the Soviet Union—one of the two superpowers—and abandonment of communist regimes in many parts of the world, some of which were violently overthrown. These events drastically altered the world's balance of power, marking the end of the Cold War and beginning of the post-Cold War era.

The earliest recorded protests, which led to the revolutions, began in Poland on 14 August 1980, the massive general strike which led to the August Agreements and establishment of Solidarity, the first and only independent trade union in the Eastern Bloc, whose peak membership reached 10 million. The main region of the 1989 revolutions was Central Europe, starting in Poland with the 1988 Polish strikes, and continued in Hungary, East Germany, Bulgaria, Czechoslovakia, and Romania. On 4 June 1989, Poland conducted the first elections that led to the dissolution of the communist government, with Solidarity winning an overwhelming victory, leading to the peaceful fall of communism in Poland. Influenced by Poland, Hungary organised round table-format talks and began dismantling its section of the Iron Curtain. In August 1989, over a quarter of the Baltic states population physically chained for 675 kilometres (419 mi) in the Baltic Way protesting the occupation by the Soviet Union, while the opening of a border gate between Austria and Hungary set in motion a peaceful chain reaction, in which the Eastern Bloc disintegrated. This led to mass demonstrations in cities of East Germany and the fall of the Berlin Wall in November 1989, which served as the symbolic gateway to German reunification in 1990. A feature common to these developments was the extensive use of campaigns of civil resistance, demonstrating popular opposition to the continuation of one-party rule and contributing to pressure for change. Romania was the only country in which citizens and opposition forces used violence to overthrow its communist regime, although Romania was politically isolated from the rest of the Eastern Bloc.

The Polish People's Republic (1952–1989), formerly the Republic of Poland (1947–1952), and also often simply known as Poland, was a country in Central Europe that existed as the predecessor of the modern-day democratic Republic of Poland. With a population of approximately 37.9 million near the end of its existence, it was the second most-populous communist and Eastern Bloc country in Europe. It was also where the Warsaw Pact was founded. The largest city and capital was Warsaw, followed by the industrial city of Łódź and cultural city of Kraków. The country was bordered by the Baltic Sea to the north, the Soviet Union to the east, Czechoslovakia to the south, and East Germany to the west.

The Polish People's Republic was a unitary communist state established in the country after the Red Army's takeover of Polish territory from German occupation in World War II. Communist control was strengthened through electoral fraud in the 1946 Polish people's referendum and the 1947 Polish parliamentary election. The Polish United Workers' Party (PZPR) became the dominant political faction in a one-party state, but the country had more liberal policies than other socialist states due to its strategic location in the Cold War and internal opposition. The state's official name was the "Republic of Poland" (Rzeczpospolita Polska) between 1947 and 1952 in accordance with the temporary Small Constitution of 1947. The name "People's Republic" was introduced and defined by the Constitution of 1952. The Polish People's Republic was dissolved following the Revolutions of 1989 and the 1990 Polish presidential election, but the post-communist Third Polish Republic retained the 1952 constitution, with amendments, until the introduction of the current constitution on 17 October 1997, abolishing the socialist structure entirely and replacing it with a parliamentary system that has remained in place to the present-day.

The history of Poland from 1945 to 1989 spans the period of Marxist–Leninist regime in Poland after the end of World War II. These years, while featuring general industrialization, urbanization and many improvements in the standard of living, were marred by early Stalinist repressions, social unrest, political strife and severe economic difficulties.Near the end of World War II, the advancing Soviet Red Army, along with the Polish Armed Forces in the East, pushed out the Nazi German forces from occupied Poland. In February 1945, the Yalta Conference sanctioned the formation of a provisional government of Poland from a compromise coalition, until postwar elections. Joseph Stalin, the leader of the Soviet Union, manipulated the implementation of that ruling. A practically communist-controlled Provisional Government of National Unity was formed in Warsaw by ignoring the Polish government-in-exile based in London since 1940.

During the subsequent Potsdam Conference in July–August 1945, the three major Allies ratified a massive westerly shift of Poland's borders and approved its new territory between the Oder–Neisse line and the Curzon Line. The area of Poland was reduced in comparison to its pre-World War II extent and geographically resembled that of the medieval early Piast dynasty era. Following the destruction of the Polish-Jewish population in the Holocaust, the flight and expulsion of Germans in the west, resettlement of Ukrainians in the east, and the expulsion and resettlement of Poles from the Eastern Borderlands (Kresy), Poland became for the first time in its history an ethnically homogeneous nation-state without prominent minorities. The new government solidified its political power, while the Polish United Workers' Party (PZPR) under Bolesław Bierut gained firm control over the country, which would remain an independent state within the Soviet sphere of influence. The July Constitution was promulgated on 22 July 1952 and the country officially became the Polish People's Republic (PRL).

The Constitution of the Polish People's Republic (also known as the July Constitution or the Constitution of 1952) was a communist state constitution that acted as the supreme law. It passed in communist-ruled Poland on 22 July 1952. It superseded the post-World War II provisional Small Constitution of 1947, which in turn replaced the pre-war April Constitution of 1935.

The 1952 constitution introduced a new name for the Polish state, the Polish People's Republic (Polska Rzeczpospolita Ludowa, PRL), replacing the previously used Republic of Poland (Rzeczpospolita Polska). The communist-led Sejm (legislature) was declared to be the highest state authority. The real source of supreme state power, the Polish United Workers' Party (PZPR), was not regulated by the constitution; it was ruled by its own statute. The constitution legalized many practices that had been introduced in Poland, in the wake of the Soviet Red Army and the Polish People's Army defeat of Nazi Germany in 1944–1945, by Polish-communist governmental bodies, including the Polish Committee of National Liberation (PKWN) and its successors.

Mieczysław Zygmunt Jagielski (12 January 1924 – 27 February 1997) was a Polish politician and economist. During the times of the People's Republic of Poland he was the last leading politician from the former eastern regions of pre-Second World War Poland.

Jagielski became a communist deputy to the legislative body of Poland, the Sejm, in 1957, and he would continue to serve in that capacity for seven consecutive terms until 1985. In 1959, he was posted to be a member of the Central Committee of the Polish United Workers' Party and appointed to be the Minister of Agriculture. After he left his position as Minister of Agriculture in 1970, Jagielski became a Deputy Prime Minister, and the next year, a member of the Politburo of the Polish United Workers' Party. In August 1980, Jagielski represented the government during talks with strikers in the city of Gdańsk. He negotiated the agreement which recognized Solidarity, a Polish trade union, as the first officially recognized independent trade union within the Eastern Bloc. Between August 1980 and August 1981, Jagielski continued to interact with representatives of Polish workers, though his health was declining during this period. In late July 1981, Jagielski was fired from the Deputy Premiership, reportedly because he failed to produce a recovery program for the economic crisis Poland was experiencing at that time. The same year, he left his membership of the Political Bureau of the Polish United Workers Party and the Central Committee. He died in Warsaw, Poland from a heart attack at the age of 73.

The 21 demands of the Inter-Enterprise Strike Committee (Polish: 21 postulatów MKS) was a list of demands issued on 17 August 1980 by the Inter-Enterprise Strike Committee in Poland.

The first demand was the right to create independent trade unions. Other demands called the government to respect the constitutional rights and freedoms, dismantling the privileges for Polish United Workers' Party members, and taking actions to improve the economic conditions of Polish citizens. The demands eventually led to the Gdańsk Agreement and creation of Solidarity.

Front of National Unity or National Unity Front (Polish: Front Jedności Narodu, FJN) was a popular front supervising elections in the Polish People's Republic which also acted as a coalition for the dominant communist Polish United Workers' Party (PZPR) and its allies. It was founded in 1952 as National Front (Front Narodowy) and renamed to Front of National Unity in 1956. It was the heir of the Democratic Bloc (Blok Demokratyczny) which ran in the elections of 1947 before the merger between communists and socialists.

The Front was created by and was subordinate to the PZPR. Its membership included all three legal Polish political parties (the PZPR, Democratic Party, and United People's Party) and many organizations (such as trade unions). During elections it had a near monopoly (varied depending on particular time) on registering candidates who had the right to participate in the elections. As was the case with other popular fronts in the Soviet bloc, the member parties of the Front were largely subservient to the PZPR; they had to accept the PZPR's "leading role" as a condition of their existence.
