The Armenian Genocide was the systematic mass murder and expulsion of 1.5 million ethnic Armenians carried out in Turkey and adjoining regions by the Ottoman government between 1914 and 1923. The starting date is conventionally held to be 24 April 1915, the day that Ottoman authorities rounded up, arrested, and deported from Constantinople (now Istanbul) to the region of Angora (Ankara), 235 to 270 Armenian intellectuals and community leaders, the majority of whom were eventually murdered.
