Reichsbrger movement
en.wikipedia.org

...Reichsbrgerbewegung ('Reich Citizens' Movement') or Reichsbrger ('Reich Citizens', the German word is the same in singular and in plural) is a label for several anticonstitutional/revisionist groups and individuals in Germany and elsewhere who reject the legitimacy of the modern German state, the Federal Republic of Germany, in favour of the German Reich, which existed from 1871 to 1945.[1][dubious " discuss]

The movement consists of very different persons with different beliefs, therefore it is difficult to define the movement and its ideology. Some groups are republican, others monarchist, some include far-right and antisemitic thoughts.

One typical belief is the claim that the German Reich[2] continues to exist in its pre-World War II borders, and that it is now governed by one of the Reichsbrger groups.

Several incidents with violent members of the movement and illegal weapons depots earned the movement the attention of the media and the German authorities.[3] ...
