English: Meeting of the NSDAP (Nazi Party) local group in Liechtenstein in Vaduz town hall.

The NSDAP/AO (Auslands-Organisation, die Auslandsorganisation der Nationalsozialistischen Deutschen Arbeiterpartei, Nazi Party/Foreign Organization) was a branch of the Nazi Party and the 43rd and only non-territorial Gau ("region") of the Party. Nazi Party members who lived outside the German Reich were pooled in this special Party department. On May 1, 1931, the "AO" was founded on the initiative of Reich Organization Leader Gregor Strasser, and its management was assigned to Hans Nieland, who resigned from office on May 8, 1933, because he had become head of the Hamburg police authority; he was replaced by Ernst Wilhelm Bohle. Only actual citizens of the German Reich with a German passport could become members of the AO. Persons of German descent, ethnic Germans (German: Volksdeutsche), who possessed the nationality of the country in which they lived, were refused entry to the Nazi Party.

The Volksdeutsche Bewegung in Liechtenstein (German National Movement in Liechtenstein, VDBLV) was a Nazi party active from 1938 to 1945. It emerged after the Anschluss of Austria, advocating for Liechtenstein’s integration into Nazi Germany. The party attempted a coup in 1939 (Anschlussputsch), which failed, leading to its decline. Despite efforts to promote Nazi ideology, including anti-Semitic propaganda and recruiting for the Waffen-SS, the party lost influence as Germany's war fortunes waned. After World War II, several members were tried and convicted for their roles in the failed coup.
