In the interwar period, it was administratively located in the Łódź Voivodeship of Poland. According to the 1921 census, Bolesławiec had a population of 1,854, 72.9% Polish and 27.1% Jewish.[4]
Following the joint German-Soviet invasion of Poland, which started World War II in 1939, Bolesławiec was occupied by Germany. Before the war, more than 500 Jews lived in Bolesławiec. Until August 1941, the village's Jews were murdered by the occupiers in the Holocaust, and some were deported to larger Jewish concentrations in the area, and they too were eventually murdered.[5] The occupiers initially renamed the village to Klein Buntzlau, and in 1943, to Bolkenburg. After the end of German occupation in 1945, the original name was restored.
