Beatrix de Courtenay held two titles, the first as Titular Countess of Edessa, a city in Upper Mesopotamia and an early centre of Syriac Christianity; what was her second title?
Edessa Edessa (Greek Ἔδεσσα , Turkish: "Şanlıurfa" ,Arabic الرها , Kurdish: Riha ) was a city in Upper Mesopotamia, founded on an earlier site by Seleucus I Nicator ca. 302 BC. It was also known as "Antiochia on the Callirhoe" from the 2nd century BC. It was the capital of the semi-independent kingdom of Osroene from c. 132 BC and fell under direct Roman rule in ca. 242. It became an important early centre of Syriac Christianity.
Metropolis of Nicaea The Metropolis of Nicaea (Greek: Μητρόπολις Νικαίας ), was an ecclesiastical province (since the mid-4th century a metropolitan bishopric) of the Patriarchate of Constantinople in the city of Nicaea in the province of Bithynia (now Iznik in Turkey). A prestigious see due to its proximity to the Byzantine capital, Constantinople, and the location of two Ecumenical Councils in 325 and 787, the metropolitan see of Nicaea remained important until its conquest by the Ottoman Turks in 1331. The Christian element in the diocese diminished rapidly after that, with the flight of the Greek population and the Islamization of the remainder. As a result, the seat of the diocese was moved to Cius. The metropolis remained active until the population exchange between Greece and Turkey in the early 1920s. It remains a titular see of the Patriarchate of Constantinople as well as being, since the mid-15th century, a titular archbishopric of the Roman Catholic Church.
