The forceful expulsion of Christians of western Anatolia , especially Ottoman Greeks , has many similarities with policy towards the Armenians , as observed by US ambassador Henry Morgenthau and historian Arnold Toynbee . In both cases , certain Ottoman officials , such as Şükrü Kaya , Nazım Bey and Mehmed Reshid , played a role ; Special Organization units and labour battalions were involved ; and a dual plan was implemented combining unofficial violence and the cover of state population policy . This policy of persecution and ethnic cleansing was expanded to other parts of the Ottoman Empire , including Greek communities in Pontus , Cappadocia , and Cilicia
