ADANA. - A city of Cilicia, situated on the Saihun River, an ancient Greek episcopal see dependent on the see of Tarsus. When the Armenian kingdom was established in Cilicia, the see of Adana also passed to the Armenian patriarchate. In the 12th–14th centuries, after the destruction of the major cities and the Egyptian invasion of Cilicia, Adana became an important historical and religious center of Armenian Cilicia. In 1310, an agreement regarding the succession to the throne of Cyprus was concluded in Adana before the delegates of the Pope, and in 1316 the penultimate general national synod of the Armenians was convened there.
