Freikorps () were German volunteer military or anti-communist paramilitary units. The term was originally applied to voluntary armies formed in German lands from the middle of the 18th century onwards. Between World War I and World War II the term was also used for the paramilitary organizations that arose during the Weimar Republic. An entire series of Freikorps awards also existed, mostly replaced in 1933 by the Honor Cross for World War I veterans.
