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.
Milicja Obywatelska
Milicja Obywatelska (; Citizens' Militia), commonly abbreviated to MO, was the national police organization of the Polish People's Republic. It was created on 7 October 1944 by the Soviet-sponsored Polish Committee of National Liberation, effectively replacing the pre-war police force. The Citizen's Militia would remain the predominant means of policing in Poland until 6 April 1990, when it was transformed back into "Policja".
