A history of the Holocaust must include the history of emotions and imagination of Germans during the Third Reich, for the fundamental reason that the persecution and extermination was built on fantasy. In persecuting and exterminating the Jews, Germans waged a war against an imaginary enemy that had no belligerent intentions toward Germany and possessed no army, state, or government.
The essential motivations for this war were not practical, for Germans and Jews did not have a conflict over territory, land, resources, borders, or political power that often characterizes cases of ethnic cleansing and genocide in the modern world. In the mind of the Nazis, this was a war about identity. Nothing about Nazi anti-Semitism was driven by a desire to provide a truthful account of reality. Yet it was nonetheless believed by many Germans and therefore was for them real and truthful.
A key to understanding this world of anti-Semitic fantasies is no longer to account for what happened—the administrative process of extermination, the racial ideological indoctrination by the regime, and the brutalizing war—because we now have sufficiently good accounts of these historical realities. Rather, a key is to account for what the Nazis thought was happening, for how they imagined their world. What was this fantasy created by Nazis and other Germans during the Third Reich, and the story that went along with it, that made the persecution and extermination of the Jews justifiable, conceivable, and imaginable?

What is the relationship between sexual and other kinds of politics? Few societies have posed this puzzle as urgently, or as disturbingly, as Nazi Germany. What exactly were Nazism's sexual politics? Were they repressive for everyone, or were some individuals and groups given sexual license while others were persecuted, tormented, and killed? How do we make sense of the evolution of postwar interpretations of Nazism's sexual politics? What do we make of the fact that scholars from the 1960's to the present have routinely asserted that the Third Reich was 'sex-hostile'? In response to these and other questions, "Sex after Fascism" fundamentally reconceives central topics in twentieth-century German history.Among other things, it changes the way we understand the immense popular appeal of the Nazi regime and the nature of antisemitism, the role of Christianity in the consolidation of postfascist conservatism in the West, the countercultural rebellions of the 1960's - 1970's, as well as the negotiations between government and citizenry under East German communism. Beginning with a new interpretation of the Third Reich's sexual politics and ending with the revisions of Germany's past facilitated by communism's collapse, "Sex after Fascism" examines the intimately intertwined histories of capitalism and communism, pleasure and state policies, religious renewal and secularizing trends. A history of sexual attitudes and practices in twentieth-century Germany, investigating such issues as contraception, pornography, and theories of sexual orientation, "Sex after Fascism" also demonstrates how Germans made sexuality a key site for managing the memory and legacies of Nazism and the Holocaust.
