The Hamidian massacres, also called the Armenian massacres, were massacres of Armenians in the Ottoman Empire in the mid-1890s. Estimated casualties ranged from 100,000 to 300,000, resulting in 50,000 orphaned children. The massacres were named after Sultan Abdul Hamid II, who, in his efforts to maintain the imperial domain of the declining Ottoman Empire, reasserted pan-Islamism as a state ideology. Although the massacres were aimed mainly at the Armenians, in some cases they turned into indiscriminate anti-Christian pogroms, including the Diyarbekir massacres, where, at least according to one contemporary source, up to 25,000 Assyrians were also killed.
