Although the site of Urfa has been inhabited since prehistoric times, the city was founded in 304 B.C. by Seleucus I Nicator and named Edessa after the ancient capital of Macedonia. In the late 2nd century, as the Seleucid dynasty disintegrated, it became the capital of the Arab Nabataean Abgar dynasty, which was successively a Parthian, Armenian, and Roman client state and eventually a Roman province. Its location on the eastern frontier of the Empire meant it was frequently conquered during periods when the Byzantine central government was weak, and for centuries, it was alternately conquered by Arab, Byzantine, Armenian, Turkish rulers. In 1098, the Crusader Baldwin of Boulogne convinced the Armenian king to adopt him and then seized power, establishing the first crusader state known as the County of Edessa and imposing Latin Christianity on the Greek Orthodox and Armenian Apostolic majority of the population. |  |
