Query: How many ethnic Armenians are believed to have died in the Armenian Genocide?
Context: In 1915, as the Russian Caucasus Army continued to advance into eastern Anatolia, the Ottoman government started the deportation of its ethnic Armenian population, resulting in the death of approximately 1.5 million Armenians in what became known as the Armenian Genocide. 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 infirm on death marches leading to the Syrian desert.
