The Austrian Resistance to the Nazi rule that started with the Anschluss in 1938. These activists, limited primarily to adherents of the political left, operated in isolation from the Austrian mainstream during the war years. One prominent activist was Josef Plieseis. Other strands of Austrian resistance included Catholics and monarchists.However, it is notable that several Austrian nationalists, some of them even with fascist sympathies, also resisted, opposed to the destruction of the Austrian state.
The movement had a prehistory of socialist and communist activism against the era of Austrofascism from 1934. Although the Austrofascist regime was itself intensely hostile to Nazism, especially after the Austrian Nazis’ failed coup attempt in 1934, known as the July Putsch.
Austrian society has had an ambivalent attitude both toward the Nazi government from 1938 to 1945 and the few that actively resisted it. Since large portions of Austrian society either actively or tacitly supported the Nazi regime, the Allied forces treated Austria as a belligerent party in the war and maintained occupation of it after the Nazi capitulation. On the other hand, the Moscow Declaration labeled Austria as a free and democratic society before the war, and considered its capture an act of liberation.
The sign of the Austrian resistance was O5, where the 5 stands for E and OE is the abbreviation of Österreich with Ö as OE. This sign may be seen at the Stephansdom in Vienna.
