Western Armenia
Western (Ottoman) Armenia was composed of six vilayets (vilâyat-ı sitte), the vilayets of Erzurum, Van, Bitlis, Diyarbekir, Kharput, and Sivas. After the collapse of Ottoman Empire Western Armenia remained under Turkish rule, and in 1894–96 and 1915 Turkey perpetrated systematic massacres and forced deportations of Armenians.
