Busra al-Harir has been identified with the Biblical city of "Bosr" where Gilead was captured by Judas Maccabeus. The town is also mentioned in the 3rd century Mosaic of Rehob. Extensive Byzantine-era ruins were found in the town. Of the ruins was a Roman temple dedicated to unspecified deity that was consecrated as a church by 517/18 CE. The temple was built by a certain Fl. Chrysaphios, but was consecrated by archdeacon Elias, a subordinate of bishop Varus of Zorava. A notable Christian family during this era, the Maiorinus, maintained their estates in Busra al-Harir. The family played an important role converting the inhabitants of the Lajat plain to Christianity. It is possible that the tomb of Elias, is that of the prophetElisha. Busra al-Harir was visited by Muslim geographer Yaqut al-Hamawi during Ayyubid rule in the 1220s. He referred to it as "Busr" and noted that it was a "village of the Hauran" in the Lajat plain. Busr contained a shrine dedicated to the prophet Joshua and the tomb of Sheikh al-Hariri. According to al-Harawi, the tomb of Elias was still revered in Busr. The Haririyya, a highly pantheist sect of the Rifa'iyyaSufi order, was founded in Busr in 1247 by its namesake Ali ibn Abi'l Hasan al-Hariri al-Marwazi. The teachings of the sect were repudiated in a fatwa by the Mamluk-era scholar Ibn Taymiyya.
During early Ottoman Empire rule, Busra al-Harir was a large village. In 1596 it appeared in the Ottoman tax registers as "Busr" and was part of the nahiya of Badi Sarma in the Hauran Sanjak. At that time it had an entirely Muslim population of 42 households and 31 bachelors, who paid fixed tax rate of 40% various agricultural products, such as wheat, barley, summer crops, goats and/or beehives; a total of 17,000 akçe. Towards the end of Ottoman rule in Syria, the residents of Busra al-Harir engaged in regular clashes with the residents of Jabal al-Druze. In 1879 fighting flared up between the townspeople and the Druze after the Muslim inhabitants of several nearby villages fled to Busra al-Harir as a result of fighting between the al-Atrash family, a leading Druze clan, and the localBedouin. With pressure from the Ottoman government in Damascus, a truce was reached that year stipulating a Druze evacuation of Muslim villages in the Hauran occupied during the previous years. By 1885 the Ottoman government set up Busra al-Harir as one of 42 stations on the telegraph grid which extended from Aleppo in the north to Gaza in the south. In 1892 Osman Nuri Pasha, the Ottoman governor of Damascus, demanded the completion of land registration in Busra al-Harir in attempt to extend central government control over the outlier Hauran and Transjordan regions. The town's inhabitants resisted the measure, leading to a shootout which resulted in the wounding of the district governor. In May 1909 a dispute between the chief of Jabal al-Druze, Yahya "Bey" Atrash, and his business partner in a steam mill in Busra al-Harir led to armed clashes between the Druze and the town's residents. The latter were supported by the Ottoman government which prepared a large army headed by Sami Pasha Faruqi to put down the Druze revolt in August 1910. Busra al-Harir was one of the principal garrison towns from which the Ottoman army launched its campaign. Atrash's forces were decisively defeated with an estimated 2,000 Druze killed and hundreds of fighters imprisoned. Consequently, the Ottoman government successfully began the process of extending direct rule to the Hauran.
Syrian Civil War
Busra al-Harir was reportedly "a stronghold of the rebel Free Syrian Army " during the 2011–2012 Syrian uprising against the government of Bashar al-Assad, according to the BBC. From the town and the nearby Lajat area, the FSA attacked military supply lines. Two residents were reported killed by security forces on 10 June 2011, according to the opposition. State television reported a policeman was shot dead in the town on 16 September. On 11 December, the Syrian Army's Izra'-based 12th Armoured Brigade stormed the town in an attempt to rout out FSA fighters.
