Paramilitary groups were formed throughout the Weimar Republic in the wake of Imperial Germany's defeat in World War I and the ensuing German Revolution. Some were created by political parties to help in recruiting, discipline and in preparation for seizing power. Some were created before World War I. Others were formed by individuals after the war and were called "Freikorps" (Free corps). The party affiliated groups and others were all outside government control, but the Freikorps units were under government control, supply and pay (usually through army sources).
