Polish People's Republic
The Polish People's Republic (, ) was a state in Central Europe that existed from 1947 to 1989, and the predecessor of the modern democratic Republic of Poland. With a population of approximately 37.9 million inhabitants near the end of its existence, it was the most populous state of the Eastern Bloc after the Soviet Union. Having a unitary Marxist–Leninist communist government, it was also one of the main signatories of the Warsaw Pact.

Administrative division of the Polish People's Republic
Administrative division of Polish People's Republic was subject to several reforms. The first of those established administrative division over the Polish territories that had shifted significantly westwardly. The Polish People's Republic administrative division was reformed in: 1946, 1950, 1957 and 1975. The 1975 division survived the fall of communism in 1990 and was replaced only in 1999 by the most current administrative division of Poland, which closely resembles the 1945-75 scheme but with different names (the Communists tended to simply name the voivodeships after their capitals, whereas the current ones use more historical names) and changes in the borders in certain areas.
