However, beginning with the Istanbul Pogrom in 1955, through 1978, the ethnic Greek community of Istanbul was reduced from 135,000 to 7,000 by a series of government orchestrated riots, pogroms and deportations. Most of Fanis' family is deported in 1964 with the Ankara government decision to renege on the 1930 Greco-Turkish Ankara Convention, affirming the right of Greek etablis (Greeks who were born and lived in Istanbul but held Greek citizenship) to live and work in Turkey, and most Greek citizens who lived in Constantinople were deported to Greece, despite most never having previously resided there. Since Vassilis was not a dual citizen, he was able to stay behind while his grandson Fanis and his parents were deported to Athens.
