Originally a part of Jund Hims, the first Umayyad caliph Mu'awiya I established the Jund Qinnasrin when he defeated Hasan ibn Ali, and subsequently detached the people of that area from their allegiance to him. 9th century Muslim historian al-Biladhuri says, however, that it was Muawiya's successor Yazid I who founded the district after separating northern territories from Jund Hims. The newly established district was named after the ancient town of Qinnasrin which was located within its boundaries. Under the Umayyads, Jund Qinnasrin composed of three districts: Antioch, Aleppo, and Manbij.[1]
After caliph al-Mansur's conquests of southern Anatolia, Syria's northern frontiers were considerably extended and in 786, during the reign of the Harun al-Rashid, the now-overgrown Jund Qinnasrin was subdivided. The area toward the northern frontier, comprising the territories of Antioch and the lands east towards Aleppo were split from the district to form Jund al-'Awasim. For the remainder of the Abbasid period, Jund Qinnasrin consisted of the cities of Aleppo (the capital of the district), Qinnasrin and the lands around them, as well as the Sarmin territory.[1]
