Polish People's Republic

he Polish People's Republic (Polish: Polska Rzeczpospolita Ludowa, PRL) covers the history of Poland under communist control between 1952 and 1989. The name was defined by the Constitution of 1952 which was based on the 1936 Soviet Constitution. Between 1947 and 1952, the name of the Polish state was the Republic of Poland (Rzeczpospolita Polska), in accordance with the temporary Constitution of 1947. At the time of its founding during final stages of World War II, Poland was regarded as a puppet entity set up and controlled by the Soviet Union, and over time, it developed into a satellite state of the Soviet Union.

The Soviet Union had much influence over both internal and external affairs, and Red Army forces were stationed in Poland (1945: 500,000; until 1955: 120,000 to 150,000; until 1989: 40,000).[3] In 1945, Soviet generals and advisors formed 80% of the officer cadre of the Polish Armed Forces. The Polish United Workers' Party became the dominant political party, officially making the country a Communist state.
