Exarchate of Arabia (Without Islam)

The Exarchate of Arabia (Hellenic: Έξαρχεῖον της Αραβίας Éxarkheîon tēs Arabías, Arabic: إكساركة العربية al-Eksarkah al-Arabiyah) was the name of an administrative division of the Roman Empire in Hejaz region of Arabia from 1554 and persisted as a Hellene colony until the First World War when Hussein ibn Ali, sharif of Mecca, declared himself king of Arabia (1916) as a result of the McMahon–Hussein Correspondence.
