During the First World War , Rûm , alongside Ottoman Greeks , were targeted by the Ittihadist Ottoman authorities in what is now historically known as the Ottoman Greek genocide . As a result , three Antiochian Greek Orthodox Dioceses were completely annihilated ; the Metropolis of Tarsus and Adana , the Metropolis of Amida , and the Metropolis of Theodosioupolis . Those Antiochians living outside of the French Mandate for Syria and the Lebanon were subject to the forced population exchange of 1923 , which ended the Ottoman Greek Genocide . One modern Greek town , which is made up of Antiochian survivors from the population exchange is Nea Selefkia , which is located in Epirus . The founders of Nea Selefkia were refugees from Silifke in Cilicia
