"Austria – the Nazis' first victim" was a political slogan first used at the Moscow Conference in 1943 which went on to become the ideological basis for Austria and the national self-consciousness of Austrians during the periods of the allied occupation of 1945-1955 and the sovereign state of the Second Austrian Republic (1955–1980s). According to the interpretation of this slogan by the founders of the Second Austrian Republic, the "Anschluss" in 1938 was an act of military aggression by the Third Reich. Austrian statehood had been interrupted and therefore the newly revived Austria of 1945 could not and should not be responsible in any way for the Nazis' crimes. The "victim theory" formed by 1949 () insisted that all the Austrians, including those who strongly supported Hitler, had been unwilling victims of a Nazi regime and therefore were not responsible for its crimes.
