According to the historical data presented by '' Al-Ghazzi '' , the vast majority of the Aleppine Christians were Catholics until the 1920s . The growth of the Orthodox and Oriental Orthodox Christian communities is tied in with the arrival of the Armenian and Assyrian genocide survivors from Cilicia and Southern Turkey , as well as large numbers of Orthodox Greeks from the Sanjak of Alexandretta who arrived in Aleppo later on after the annexation of the Sanjak in 1939 by Turkey
