Diyār Muḍar

Diyār Muḍar was a frontier region in the western part of Al-Jazīrah, a historical region in the northern Middle East situated between the Euphrates and Tigris rivers. This area, which now comprises parts of northeastern Syria and southeastern Turkey, was a significant crossroads for trade and cultural exchange in ancient and medieval times.1

Diyār Muḍar experienced periods of division and conflict. In the late 11th century, it was briefly split into two kingdoms: a Crusader Armenian state at Edessa and a Turkish Muslim kingdom at Harran. Zangī's capture of Edessa in 1144 brought Diyār Muḍar back under Muslim control. The region later saw increased influence from Turkmen tribes, with the Ak Koyunlu taking control around 1402. Diyār Muḍar eventually became part of the Ottoman Empire in the early 17th century and has been divided between Turkey and Syria since 1918.1
