In April 1915 the Ottoman government embarked upon the systematic decimation of its civilian Armenian population. The persecutions continued with varying intensity until 1923 when the Ottoman Empire ceased to exist and was replaced by the Republic of Turkey. The Armenian population of the Ottoman state was reported at about two million in 1915. An estimated one million had perished by 1918, while hundreds of thousands had become homeless and stateless refugees. By 1923 virtually the entire Armenian population of Anatolian Turkey had disappeared.
The Ottoman Empire was ruled by the Turks who had conquered lands extending across West Asia, North Africa and Southeast Europe. The Ottoman government was centered in Istanbul (Constantinople) and was headed by a sultan who was vested with absolute power. The Turks practiced Islam and were a martial people. The Armenians, a Christian minority, lived as second class citizens subject to legal restrictions which denied them normal safeguards. Neither their lives nor their properties were guaranteed security. As non-Muslims they were also obligated to pay discriminatory taxes and denied participation in government. Scattered across the empire, the status of the Armenians was further complicated by the fact that the territory of historic Armenia was divided between the Ottomans and the Russians.
In its heyday in the sixteenth century, the Ottoman Empire was a powerful state. Its minority populations prospered with the growth of its economy. By the nineteenth century, the empire was in serious decline. It had been reduced in size and by 1914 had lost virtually all its lands in Europe and Africa. This decline created enormous internal political and economic pressures which contributed to the intensification of ethnic tensions. Armenian aspirations for representation and participation in government aroused suspicions among the Muslim Turks who had never shared power in their country with any minority and who also saw nationalist movements in the Balkans result in the secession of former Ottoman territories. Demands by Armenian political organizations for administrative reforms in the Armenian-inhabited provinces and better police protection from predatory tribes among the Kurds only invited further repression. The government was determined to avoid resolving the so-called Armenian Question in any way that altered the traditional system of administration. During the reign of the Sultan Abdul Hamid (Abdulhamit) II (1876-1909), a series of massacres throughout the empire meant to frighten Armenians and so dampen their expectations, cost up to three hundred thousand lives by some estimates and inflicted enormous material losses on a majority of Armenians.
