Schmitt joined the Nazi Party on 1 May 1933. Within days, he supported the party in the burning of books by Jewish authors, rejoiced in the burning of "un-German" and "anti-German" material, and called for a much more extensive purge, to include works by authors influenced by Jewish ideas. In July Hermann Göring appointed him State Councillor for Prussia, and in November he became the president of the "Union of National-Socialist Jurists". He also replaced Heller as a professor at the University of Berlin, a position he held until the end of World War II. He presented his theories as an ideological foundation of the Nazi dictatorship and a justification of the "Führer" state concerning legal philosophy, particularly through the concept of "auctoritas".
