New research on the darkest chapter of World War I: the authors examine the strategies and calculations employed by the Habsburg ruling elite. They show how the war, which began with the main aim of destroying Serbia, was allowed to get out of hand, with no consideration of the losses. And what happened in the zones occupied by the Imperial armies? Were Austro-Hungarian forces responsible for war crimes? This book sheds a shocking light on chains of command, prejudices, and escalating violence towards suspects, civilians and ‘administrated masses’. A disturbing panorama of the Habsburg Empire’s path to downfall.
