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. The official capital since 1947 and largest city was Warsaw, followed by industrial Łódź and cultural Kraków.
Polish People's Republic
The Polish People's Republic was divided into several voivodeships (the Polish unit of administrative division). After World War II, the new administrative divisions were based on the pre-war ones. The areas in the East that were not annexed by the Soviet Union had their borders left almost unchanged. Newly acquired territories in the west and north were organised into the voivodeships of Szczecin, Wrocław, Olsztyn and partially joined to Gdańsk, Katowice and Poznań voivodeships. Two cities were granted voivodeship status: Warsaw and Łódź.
In 1950 new voivodeships were created: Koszalin - previously part of Szczecin, Opole - previously part of Katowice, and Zielona Góra - previously part of Poznań, Wrocław and Szczecin voivodeships. In addition, three other cities were granted the voivodeship status: Wrocław, Kraków and Poznań.
