As control of the Polish territories passed from occupying forces of Nazi Germany to the subsequent occupying forces of the Soviet Union, and from the Soviet Union to the Soviet-imposed puppet satellite government, Poland's new economic system was forcibly imposed and began moving towards a radical, communist centrally planned economy. One of the first major steps in that direction involved the agricultural reform issued by the Polish Committee of National Liberation government on 6 September 1944. All estates over 0.5 km2 in pre-war Polish territories and all over 1 km2 in former German territories were nationalised without compensation. In total, 31,000 km2 of land were nationalised in Poland and 5 million in the former German territories, out of which 12,000 km2 were redistributed to farmers and the rest remained in the hands of the government (Most of this was eventually used in the collectivization and creation of sovkhoz-like State Agricultural Farms "PGR"). However, the collectivization of Polish farming never reached the same extent as it did in the Soviet Union or other countries of the Eastern Bloc.Wojciech Roszkowski, Reforma Rolna Encyklopedia.PWN.pl (Internet Archive)
