The movement has used some of the concepts and techniques of the One People's Public Trust, an American sovereign citizen movement operated by pseudolaw ideologue Heather Ann Tucci-Jarraf. Historical revisionism The self-described Reichsbürger maintain that the Federal Republic of Germany is illegitimate and that the Reich's 1919 Weimar Constitution (or an earlier constitution) remains in effect.
