The Nazi book burnings were a campaign conducted by the German Student Union (Deutsche Studentenschaft, DSt) to ceremonially burn books in Nazi Germany and Austria in the 1930s. The books targeted for burning were those viewed as being subversive or as representing ideologies opposed to Nazism. These included books written by Jewish, half-Jewish, communist, socialist, anarchist, liberal, pacifist, and sexologist authors among others. The initial books burned were those of Karl Marx and Karl Kautsky, but came to include very many authors, including Albert Einstein, Helen Keller, writers in French and English, and effectively any book incompatible with Nazi ideology. In a campaign of cultural genocide, books were also burned en masse by the Nazis in occupied territories, such as in Poland.
On April 8, 1933, the Main Office for Press and Propaganda of the German Student Union (DSt) proclaimed a nationwide "Action against the Un-German Spirit", which was to climax in a literary purge or "cleansing" ("Säuberung") by fire. According to historian Karl Dietrich Bracher:
[T]he exclusion of "Left", democratic, and Jewish literature took precedence over everything else. The black-lists ... ranged from Bebel, Bernstein, Preuss, and Rathenau through Einstein, Freud, Brecht, Brod, Döblin, Kaiser, the Mann brothers, Zweig, Plievier, Ossietzky, Remarque, Schnitzler, and Tucholsky, to Barlach, Bergengruen, Broch, Hoffmannsthal, Kästner, Kasack, Kesten, Kraus, Lasker-Schüler, Unruh, Werfel, Zuckmayer, and Hesse. The catalogue went back far enough to include literature from Heine and Marx to Kafka.
Local chapters were to supply the press with releases and commissioned articles, sponsor well-known Nazis to speak at public gatherings, and negotiate for radio broadcast time. The DSt had contacted an official from the Propaganda Ministry to request support for their campaign, including having Propaganda Minister Josef Goebbels be the main speaker at the event in Berlin.
