Arbeitslager (German pronunciation: [ˈʔaʁbaɪtsˌlaːɡɐ]) is a German language word which means labor camp. Under Nazism, the German government (and its private-sector, Axis, and collaborator partners) used forced labor extensively, starting in the 1930s but most especially during World War II. Another term was Zwangsarbeitslager ("forced labor camp").
