The eleven essays that comprise this book offer an integrated perspective on Nazi policies of mass murder. Drawing heavily on primary sources from European and American archives, the collection of essays provides novel interpretations of Nazi policies vis-à-vis ethnic, religious, and sexual minorities in the German-occupied territories, specifically Eastern Europe. The essays printed in this volume advance two main theses, drawing a line under the Functionalist-Intentionalist debate regarding the origins of Nazi genocide. In their dealing with the “lesser races,” the Nazis proved more flexible and less single-minded than has been conventionally believed. Faced with what they saw as a temporary military setback, the Nazis were willing to renegotiate their murderous policies, granting certain concessions to the minority groups otherwise slated for destruction. In the long run, however, the Nazis never abandoned the ideology of racial exclusiveness, which had contributed to their ultimate defeat. Another thesis concerns the complex ethno-political landscape of Eastern Europe that came under Nazi domination. German occupation authorities encouraged ethnic rivalries and grievances, which trace back to the Austro-Hungarian and Russian Empires and beyond. Hobbesian war of all against all that had ensued made it easier for the Nazis to apply a divide-and-rule policy. It also provided a fertile ground for collaboration, specifically in the mass murder of Jews. The book will appear to both academic and non-academic audiences interested in the subjects as diverse as genocide, ethno-nationalism, and minority studies.
