Jabiyah was a town of political and military significance in the 6th–8th centuries. It was located between the Hawran plain and the Golan Heights. It initially served as the capital of the Ghassanids, an Arab vassal kingdom of the Byzantine Empire. Following the Muslim conquest of Syria, it early on became the Muslims' main military camp in the region and, for a time, the capital of Jund Dimashq. Caliph Umar convened a meeting of senior Muslim figures at the city where the organization of Syria and military pay were decided. Later, in 684, Jabiyah was the site of a summit of Arab tribes that chose Marwan I to succeed Caliph Mu'awiya II. Jabiyah was often used by the Umayyad caliphs as a retreat. Its significance declined when Caliph Sulayman made Dabiq the Muslims' main military camp in Syria. It was located west of the city of Nawa, Daraa.
