was sparked in the Hauran in 2011, it became a major conflict zone between rebels and government forces in the Daraa Governorate campaign until the government reasserted control in 2018. The wide availability of basalt in the Hauran led to the development of a distinct vernacular architecture characterized by the exclusive use of basalt as a building material and a fusion of Hellenistic, Nabatean and Roman styles. The durability of basalt is credited for the Hauran's possession of one of the highest concentrations of well-preserved Classical-era monuments in the world. Hauran towns such as Bosra, Qanawat, Shahba, Salkhad, Umm al-Jimal and numerous others contain Roman temples and theaters, Byzantine-era churches and monasteries, and forts, mosques and bathhouses built by successive Muslim dynasties. Geography Geographic definition Though its geographic definition may vary, the Hauran generally consists of the following subregions: the Hauran plain, which forms the heart of the region; the mountains of Jabal Hauran (also known as 'Jabal al-Druze' or 'Jabal al-Arab') east of the plain; and the Lajat volcanic field to the north of Jabal Hauran. The region is bound to the north by the Ghouta and Marj plains around Damascus and to the south by the desert steppe of Jordan. Its western boundary is marked by the Ruqqad tributary, which separates it from the Golan Heights (al-Jawlān in Arabic). It is eastwardly bound by the al-Hamad and al-Safa desert steppes. Geographer John Lewis Burckhardt, writing in 1812, defined it as follows: To the south of Jabal Kiswah and Jabal Khiyara begins the country of Hauran. It is bordered on the east by the rocky district of Lajat, and by the Jabal Hauran, both of which are sometimes comprised within the Hauran ... To the southeast, where Bosra and Ramtha are the farthest inhabited villages, the Hauran borders upon the desert. Its western limits are the chain of villages on the Hajj road, from Ghabaghib as far south as Ramtha ... Hauran comprises therefore part of Trachonitis and Iturea, the whole of Auranitis, and the northern districts of Batanea. The plain of Hauran stretches between the Marj plain of Damascus southward into modern-day Jordan where it borders Jabal Ajlun to the southwest and the desert steppe to the south and southeast. To the west is the Golan plateau and to the east are the uplands of Jabal Hauran. The plain has historically been divided into the northern Jaydur and
