These bishops belonged to the Armenian church. They ruled alongside Jacobite, Byzantine and Latin bishops.
In the first half of the twelfth century, during the period of the Crusades and the county of Edessa, there was a Latin rite archdiocese based in the city. It seems to have displaced the Byzantine bishop, but ruled alongside the Jacobite and Armenian bishops. From the 13th century on, titular bishops were sometimes appointed.
