Weimar paramilitary groups

Weimar paramilitary groups were militarily organized units that were formed outside of the regular German Army following the defeat of the German Empire in World War I. The most prominent of them, the Freikorps, were combat units that were supported by the German government and used to suppress uprisings from both the Left and the Right. There were also Citizens' Defense (Einwohnerwehr) groups to maintain public order and paramilitary groups associated with specific political parties or institutions to protect and promote their interests.
