On April 6, 1933, the German Student Association's Main Office for Press and Propaganda proclaimed a nationwide “Action against the Un-German Spirit,” to climax in a literary purge or “cleansing” (Säuberung) by fire. Local chapters were to supply the press with releases and commissioned articles, sponsor well-known Nazi figures to speak at public gatherings, and negotiate for radio broadcast time. On April 8 the students association also drafted its twelve "theses"—deliberately evocative of Martin Luther—declarations and requisites of a "pure" national language and culture. Placards publicized the theses, which attacked “Jewish intellectualism,” asserted the need to “purify” the German language and literature, and demanded that universities be centers of German nationalism. The students described the “action” as a response to a worldwide Jewish “smear campaign” against Germany and an affirmation of traditional German values.

In a symbolic act of ominous significance, on May 10 the students burned upwards of 25,000 volumes of “un-German” books, presaging an era of state censorship and control of culture. On the night of May 10, in most university towns, right-wing students marched in torchlight parades “against the un-German spirit.” The scripted rituals called for high Nazi officials, professors, rectors, and student leaders to address the participants and spectators. At the meeting places, students threw the pillaged and unwanted books into the bonfires with great joyous ceremony, band-playing, songs, “fire oaths,” and incantations.
