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").
The Nazis operated several categories of Arbeitslager for different categories of inmates. The largest number of them held civilians forcibly abducted in the occupied countries (see Łapanka for Polish context) to provide labour in the German war industry, repair bombed railroads and bridges, or work on farms and in stone quarries.[1]
The Nazis also operated concentration camps, some of which provided free forced labor for industrial and other jobs while others existed purely for the extermination of their inmates. A notable example is Mittelbau-Dora labor camp complex that serviced the production of the V-2 rocket. See List of German concentration camps for more. The large chemical works at Monowitz and owned by IG Farben was near Auschwitz and was designed to produce synthetic rubber and fuel oil. The labour needed for its construction was supplied by several labour camps around the works. Some of the prisoners were Auschwitz inmates, who were selected for their technical skills, such as Primo Levi for example.
