Lower Silesia also belonged to the territories that became Polish after the Potsdam Conference in the summer of 1945. The first refugee movements west from the Red Army and arbitrary forced migration of the Germans by Polish militias and military already began in autumn 1944. The arrival of many Poles from the East intensified housing shortages and supply problems. The systematic forced resettlement of the German population, especially in the Soviet and British occupation zones, took place only in 1946, parallel to the forced resettlement of the Poles, which had to leave the former Polish eastern territories. Both Germans and Poles did not have much influence on where they would end up.
