The book “Massacre in Armenia” published in Russian for the first time was written by a Bedouin, an Arab from Syria, Fayez el-Husein. An eyewitness to the Armenian genocide during the First World War in the Ottoman Empire, Fayez el-Hussein wrote down his memories in 1916, when the details of the tragedy he saw were still fresh in his memory. As a humanist, he considered it his civic duty to testify for history. But first of all, as a deeply religious Muslim, he wanted to defend “the Islamic faith from possible accusations of fanaticism from Europeans” and show that the atheistic government of the Young Turks was responsible for the crimes committed. The publication contains an extensive introduction by J. Guaita, as well as his study of the historicity of Fayez’s work el-Husein. In addition, it is equipped with a large scientific and historical apparatus that helps the reader in a deeper perception of el-Hussein’s text. The book contains numerous photographs. The proposed book is of great interest to those who study the history of the Middle East and, in particular, Armenia during the First World War.
