Zwangsarbeitslager für Juden (ZALfJ, transl.
'forced labor camps for Jews') were a network of camps established and operated by Nazi Germany for the exploitation of Jewish forced labor.
These camps were more numerous than ghettos in many parts of German-occupied Poland.
After 1943, many of the camps were integrated into the larger network of Nazi concentration camps.
