During World War II, the Germany military (Wehrmacht) helped fulfill Nazism's racial, political, and territorial ambitions. In all the lands the Germans conquered, but most egregiously in eastern Europe, the Wehrmacht targeted Jews and other supposed racial inferiors, civilian and military alike, for abuse and death.
