This anthology offers readers a collection of essays written from a multi-disciplinary perspective about the genocide of Assyrians/Aramaeans during the First World War, which is also known as 'Sayfo' (sword). The issues concerning the historicity of the genocide of the First World War, commonly known and referred to as the Armenian genocide have been widely discussed by scholars across different academic disciplines for a long time. However, very few know of the genocide of the Assyrians/Aramaeans, which took place in the same geography and at the same time. Drawing on the expertise of scholars from a variety of backgrounds, this anthology specifically seeks to shed light on this genocide from a multidisciplinary perspective and serve as a step for developing the future scholarship about the Sayfo. The essays are selection of papers presented at the SAYFO 1915: An International Conference on the Genocide of Assyrians/Aramaeans during the First World War (Freie Universität Berlin, 24-28 June 2015).
