On 24 April 1915, the day when the Armenian Genocide officially began, he was arrested and put on a train the next day together with 180 other Armenian notables and sent to the city of Çankırı in northern Central Anatolia, at a distance of some 300 miles.
In the autumn of 1916, he was taken to a hospital in Constantinople, Hôpital de la paix, and then moved to Paris in 1919, where he died in a psychiatric clinic in Villejuif in 1935.
