 Cyzicus was captured temporarily by the Arabs led by Muawiyah I in AD 675.It appears to have been ruined by a series of earthquakes beginning in 443, with the last in 1063.Although its population was transferred to Artake before the 13th century when the peninsula was occupied by the Crusaders, in 1324 the metropolitan of Cyzicus was one of three sees in Anatolia which was able to contribute a temporary annual subsidy to the Patriarchate of Constantinople.
