In 1915, the Ottoman Empire systematically carried out the Armenian genocide. This was preceded by a wave of massacres in the years 1894 to 1896, and another one in 1909 in Adana. On 24 April 1915, Ottoman authorities rounded up, arrested, and deported 235 to 270 Armenian intellectuals and community leaders from Constantinople to the region of Ankara, where the majority of which were murdered. The genocide was carried out during and after World War I and implemented in two phases—the wholesale killing of the able-bodied male population through massacre and subjection of army conscripts to forced labour, followed by the deportation of women, children, the elderly, and the infirm on death marches leading to the Syrian Desert. Driven forward by military escorts, the deportees were deprived of food and water and subjected to periodic robbery, rape, and massacre.
