The Armenian Genocide of 1915–1917 represents one of the most consequential episodes of mass violence in modern history and remains a central case study in genocide scholarship. This article examines the destruction of Armenian communities within the Ottoman Empire during the First World War, focusing on the relationship between state policy, wartime security concerns, demographic transformation, and genocidal intent. Drawing upon Ottoman archival materials, diplomatic correspondence, survivor testimonies, demographic studies, and the broader historiography of genocide studies, this article analyzes the mechanisms through which mass deportation evolved into systematic destruction.
