The Hauran (; also spelled Hawran or Houran) is a region that spans parts of southern Syria and northern Jordan. It is bound in the north by the Ghouta oasis, eastwards by the al-Safa field, to the south by Jordan's desert steppe and to the west by the Golan Heights. Traditionally, the Hauran consists of three subregions: the Nuqrah and Jaydur plains, the Jabal al-Druze massif, and the Lajat volcanic field. The population of the Hauran is largely Arab, but religiously heterogeneous; most inhabitants of the plains are Sunni Muslims belonging to large agrarian clans, while Druze form the majority in the eponymous Jabal al-Druze and a significant Greek Orthodox and Greek Catholic minority inhabit the western foothills of Jabal al-Druze. The region's largest towns are Daraa, al-Ramtha and al-Suwayda. From the mid-1st century BCE, the region was governed by the Roman Empire's Herodian and Nabatean client kings until it was formally annexed by the empire in the 2nd century CE. The Hauran prospered under Roman rule (106–395 CE) and its villages functioned as largely self-governing units, some of which developed into imperial cities. The region continued to prosper in the Byzantine era (395–634), during which different Arab tribes ruled the Hauran on Byzantium's behalf, including the Salihids (5th century) and Ghassanids (6th century) until the Muslim conquest in the mid-630s. For much of the Islamic era until Ottoman rule (1517–1917), the Hauran was divided into the districts of al-Bathaniyya and Ḥawrān, which corresponded to the Classical Batanea and Auranitis. Medieval Muslim geographers variously described these districts as prosperous, well-watered and well-populated. Under the Romans, the grain of Batanea and the wine of Auranitis were important for imperial trade, and throughout its history, the Hauran was the major source of the Levant's grain. The region saw a decline in the 17th century until increased demand for Syrian grain and improved security led to the agricultural revival and re-population of the Hauran in the mid-19th century. The region also historically benefited as a key transit area on the traditional Hajj caravan route to Mecca and later the Hejaz railway. The Hauran remained Syria's breadbasket until being largely supplanted by northern Syria in the mid-20th century, which coincided with its separation from interdependent areas due to international borders and the Arab–Israeli conflict. Nonetheless, it persisted as an important agricultural and commercial transit area into the 2000s. During the Syrian Civil War, which
