Constitution of the Polish People's Republic in the context of "Polish United Workers' Party"

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 Republic of Poland (Polish: Konstytucja Rzeczypospolitej Polskiej or Konstytucja RP for short) is the supreme law of the Republic of Poland, which is also commonly called the Third Polish Republic (Polish: III Rzeczpospolita or III RP for short) in contrast with the preceding systems.

The current constitution was ratified on 2 April 1997. The Constitution is also commonly referred to as the 1997 Constitution. It replaced the Small Constitution of 1992, a revision of the 1952 Constitution of the Polish People's Republic. It was adopted by the National Assembly of Poland on 2 April 1997, approved by a national referendum on 25 May 1997, promulgated by the President of the Republic on 16 July 1997, and came into force on 17 October 1997.

The Small Constitution of 1947 (Polish: Mała Konstytucja z 1947) was a temporary constitution issued by the communist-dominated Sejm (Polish parliament) on 19 February 1947. It confirmed the practice of separation of powers and strengthened the Sejm. It was renewed in 1949, 1950, and 1951. It recognized some articles of the March Constitution of Poland (1921) and the PKWN Manifesto (1944), whereas the April Constitution of 1935 was not recognized. The Small Constitution was replaced in 1952 by the Constitution of the Polish People's Republic.

The Small Constitution of 1992 (Polish: Mała Konstytucja z 1992) was a constitution regulating relations between the legislative and executive branches of the government of Poland, and local self-government. It was voted after the fall of communism, by Poland's first freely-elected Sejm (parliament).

It annulled some of the most outdated parts of the communist 1952 Constitution of the Polish People's Republic, in particular replacing statements about Poland being a socialist state with those appropriate for a liberal democracy and market economy.

The Polish People's Army (Polish: Ludowe Wojsko Polskie, pronounced [luˈdɔvɛ ˈvɔjskɔ ˈpɔlskʲɛ]; LWP) was the second formation of the Polish Armed Forces in the East during the latter stages of the Second World War (1943–1945), and subsequently the armed forces of the Polish communist state (1945–1989), which was formalized in 1952 as the Polish People's Republic.

The creation of communist-led Polish armed forces that were outside the command of the Polish government-in-exile was allowed and facilitated by Soviet leader Joseph Stalin, following efforts made in the early 1940s by Soviet-based Polish exiles Wanda Wasilewska and Zygmunt Berling.
