Provisional Imperial Government
A Provisional Imperial Government (German: Kommissarische Reichsregierung) is an organization or group claiming to be the legitimate government of Germany, arguing that the Federal Republic of Germany (the actual government) is an illegal regime and that their own version of "Germany" (usually based on the constitution of the Weimar Republic) represents the "true" German state in the borders of 1937.
There are multiple competing groups and individuals making these claims. Currently, approximately 60 "real" Germanies exist.
This is achieved by heavy quote mining from politicians up until the German Reunification in 1990. Very popular is referring to a 1973 ruling of the German Constitutional Court, which states that the German Empire did not end with the fall of Nazi Germany and endures, although it cannot act as an entity. What is not quoted is the next part, which elaborates that the German Federal Republic is a reorganisation of the German Empire and thus the same entity, but not with the same borders. After the reunification, the entire German state is represented by the Federal Republic; despite that, PIGs continue to bloom.
Most, if not all, Provisional Imperial Governments are watched by the German Federal Office for the Protection of the Constitution (Bundesverfassungsschutz), as they are made up by either Neo-Nazis (who just hate the modern Federal Republic of Germany that made their party illegal), extreme right wing nuts (who think the Federal Republic will crash and burn every minute and their Germany will take over), or speeding ticket evaders. It is odd that such far right groups would attempt to claim that the Weimar Republic is still in effect, considering how that constitution tried to be a democracy, but was brought down thanks to the Great Depression and some Austrian ex-corporal who had a chip on his shoulder. Several Provisional Imperial Governments have issued death threats against "traitors".
