This book represents a new reading of a key moment in the history of East European Jewry, namely the period preceding the collapse of the Russian Empire. Offering a novel analysis of relations between the Russian army and Jews during the First World War, it points to the army and military authorities as the 'gravediggers' of the Jews' fragile co-existence with the tsarist regime. It focuses on various aspects of the Russian army's brutal treatment of Jews living in or near the Eastern Front, where three quarters of European Jewry were living when the war began. At the same time, it shows the enormous harm this anti-Jewish campaign wreaked on the Russian empire's economy, finances, public security, and international status.
