The Degenerate Art Exhibition (German: Die Ausstellung "Entartete Kunst") was an art exhibition organized by Adolf Ziegler and the Nazi Party in Munich from 19 July to 30 November 1937. The exhibition presented 650 works of art, confiscated from German museums, and was staged in counterpoint to the concurrent Great German Art Exhibition. The day before the exhibition started, Hitler delivered a speech declaring "merciless war" on cultural disintegration, attacking "chatterboxes, dilettantes and art swindlers".Degenerate art was defined as works that "insult German feeling, or destroy or confuse natural form or simply reveal an absence of adequate manual and artistic skill". One million people attended the exhibition in its first six weeks. A U.S. critic commented "there are probably plenty of people—art lovers—in Boston, who will side with Hitler in this particular purge".
Hitler's rise to power on 30 January 1933 was quickly followed by actions intended to cleanse the culture of degeneracy: book burnings were organized, artists and musicians were dismissed from teaching positions, and museum curators were replaced by Party members. In September 1933 the Reichskulturkammer (Reich Culture Chamber) was established, administered by Joseph Goebbels, Hitler's Reichminister für Volksaufklärung und Propaganda (Reich Minister for Public Enlightenment and Propaganda).
The arbiter of what was unacceptably "modern" was Hitler. Although Goebbels and some others admired the Expressionist works of artists such as Emil Nolde, Ernst Barlach, and Erich Heckel, a faction led by Alfred Rosenberg despised the Expressionists, and the result was a bitter ideological dispute which was settled only in September 1934, when Hitler—who denounced modern art and its practitioners as "incompetents, cheats and madmen"— declared that there would be no place for modernist experimentation in the Reich.
