During World War II the Germans established two forced labour camps in the town, mainly for the Soviets. The territory was conquered by Red Army forces during the Vistula-Oder Offensive in the final stage of World War II. In accordance with the Potsdam Agreement, the town was incorporated into the Republic of Poland by the implementation of the Oder–Neisse line in 1945, while the remaining German population was expelled. The remaining Polish inhabitants were joined by Poles displaced from former eastern Poland annexed by the Soviet Union. The historic Polish name Sulechów was restored.
