The Kyffhäuserbund (English: Kyffhäuser League) is an umbrella organization for war veterans' and reservists' associations in Germany based in Rüdesheim am Rhein.
The difficult circumstances of World War I's postwar years led to a significant shrinking of the veterans' associations and their role.
All its surviving local associations, which in the last phase of the war effort became the breeding ground for Volkssturm units, were also placed under the direct orders of the Nazi Party.
After Nazi Germany's defeat in World War II, the Allied military governments issued a special law, Kontrollratsgesetz Nr.
This denazification decree outlawed the Nazi Party and all of its branches, effectively disbanding the Kyffhäuserbund's avatar that had been established during the Third Reich.
