The Istanbul trials of 1919–1920 were courts-martial of the Ottoman Empire that occurred soon after the Armistice of Mudros, in the aftermath of World War I. The leadership of the Committee of Union and Progress (CUP) and selected former officials were charged with several charges including subversion of the constitution, wartime profiteering, and the massacres of both Armenians and Greeks. The court reached a verdict which sentenced the organizers of the massacres – Talat, Enver, and Cemal – and others to death.
