In 1740 Silesia (and so Leubus) was taken from Austria by the Kingdom of Prussia. Municipal law was lost in 1740, and irrevocably in 1844. In 1810, the abbey was secularized and closed down by the Prussian administration, and in 1830 a psychiatric hospital was placed there. From 1871 until 1945 Leubus belonged to the German Empire, Weimar Republic and finally Nazi Germany. During World War II, it was the location of a forced labour subcamp of the Nazi prison for youth in Wołów, and in 1942–1943, also a forced labour camp for hundreds of Luxembourgers deported from German-occupied Luxembourg. The Luxembourgish prisoners were then either sent to other concentration camps or murdered by the Germans in the village. In January 1945, the settlement was seized by the Red Army without resistance. Afterwards, it passed again to Poland, although with a Soviet-installed communist regime, which remained in power until the Fall of Communism in the 1980s. Soviet troops occupied parts of the village until 1948, and the remaining German inhabitants who were not evacuated, were expelled in accordance with the Potsdam Agreement. The first enterprise launched after the war was the distillery, launched in May 1945 with the help of former Polish forced labourers who still remained in the settlement. In 1945–1947, the settlement was repopulated by Poles displaced from Żydaczów and Poznanka in former eastern Poland annexed by the Soviet Union and Polish repatriates from France.
