Polish Committee of National Liberation
Milicja Obywatelska (), in English known as the Citizens' Militia and commonly abbreviated to MO, was the national police organization of the Polish People's Republic. It was established on 7 October 1944 by the 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 10 May 1990, when it was transformed back into "Policja".
