This chapter details the rapid and radical changes experienced by Jews in Nazi Germany, focusing on the ways in which Baeck reacted to the annexation of Austria, the November Pogrom (Kristallnacht), and the German genocidal politics. Besides detailing Baeck’s political activities, this chapter is the first to offer a full analysis of his most contested work, a 1200-page unpublished manuscript he co-authored with Leopold Lucas and Hilde Ottenheimer. Although Baeck claimed it was produced for the conservative resistance, archival documents suggest it was written at the command of Nazi officers. Baeck’s discussions of race and Jewish colonization throughout history as they appear in this text reveal that he is treading very cautiously, citing Nazi scholarship on the one hand, while insisting on the rights of Jews on the other. This ambiguity is best explained by treating this manuscript as forced intellectual labor, an understanding that sheds light on Baeck’s imperial imagination at a time when the organization he headed came under Nazi supervision. Now named the Reich Association of Jews in Germany, needed to make difficult choices, including regarding deportations.
