Bilad al-Sham

Following the consolidation of Islamic hegemony over Arabia and its nomadic Arab tribes in the Ridda wars of 632–633, the caliph (leader of the Muslim community) Abu Bakr (r. 632–634) turned the nascent Muslim state's energies toward the conquest of Syria.[4] The conquest unfolded in three main phases, according to the historian Fred Donner. In the first phase, Abu Bakr dispatched four armies from Medina in late 633 led by the commanders Amr ibn al-As, Yazid ibn Abi Sufyan, Shurahbil ibn Hasana, all veterans of the Ridda wars, and Abu Ubayda ibn al-Jarrah, a leading companion of Muhammad.[5] Abu Ubayda may not have been dispatched until 636.[6] Each commander was assigned to a different zone, with Amr entrusted over Palestine, Yazid to the Balqa (central Transjordan), Shurahbil to southern Transjordan, and Abu Ubayda to the Ghassanid stomping grounds of the Golan Heights.[7] The Muslim commanders mainly engaged in small-scale skirmishes in the southern Syrian countryside with local garrisons.[8] The goal of the Muslims at the start of the conquest was likely bringing the Arabic-speaking nomadic, semi-nomadic, and settled tribesmen of the southern Syrian desert fringes under their control.[9]

The second phase began with the arrival of Khalid ibn al-Walid and his troops to Syria in 634.[8] Under Khalid's supreme command, the Muslim armies besieged and captured the southern Syrian urban centers of Bosra, Damascus, Beisan (Scythopolis), Pella, Gaza, and temporarily, Homs (Emesa) and Baalbek (Hierapolis).[10] Heraclius responded by deploying successive imperial armies against the Muslims. The Byzantines were decisively defeated in the resulting major battles of Ajnadayn in Palestine and Fahl and Yarmouk in Transjordan, all occurring in 634–636. The Muslim battlefield victories effectively ended organized resistance by the Byzantines.[10]

In the third phase, beginning about 637, the Muslim armies quickly occupied the northern Syrian countryside, while steadily conquering individual towns throughout the region whose garrisons held out alone following the breakdown of the imperial defense. Among the towns, a number of which held out until 647 or 648, were Aleppo (Beroea) and Qinnasrin (Chalcis) in the north, Hama, Homs and Baalbek (the latter two possibly for the second time), Damascus possibly for the second time, Jerusalem, and the Mediterranean coastal towns of Beirut, Sidon, Tyre, Caesarea, Antioch, Tripoli and Ascalon.[10]

The population of the region did not become predominantly Muslim and Arab in identity until nearly a millennium after the conquest. Following the Muslim conquest, Mu'awiya ibn Abi Sufyan (602–680 CE) of the Banu Umayya clan governed the Syrian region for twenty years, and developed the province as his family's power base. Relying on Syrian military support, Mu'awiya emerged as the victor in the First Fitna (656–661) and established the Umayyad Caliphate (661).

Under the Umayyads, Damascus was the capital of the Caliphate and Syria formed the Caliphate's metropolitan province; likewise, the elite Syrian army, the Ahl al-Sham (أَهْـل الـشَّـام), formed the main pillar of the Umayyad government.

Al-Sham became much less important under the Abbasid Caliphate, which succeeded the Umayyads in 750. The Abbasids moved the capital first to Kufa, and then to Baghdad and Samarra, all of which were in Iraq, which consequently became their most important province. The mainly Arab Syrians were marginalized by Iranian and Turkish forces who rose to power under the Abbasids, a trend which also expressed itself on a cultural level. From 878 until 905, Syria came under the effective control of the Tulunids of Egypt, but Abbasid control was re-established soon thereafter. It lasted until the 940s, when the province was partitioned between the Hamdanid Emirate of Aleppo in the north and Ikhshidid-controlled Egypt in the south. In the 960s the Byzantine Empire under Nikephoros II Phokas conquered much of northern Syria, and Aleppo became a Byzantine tributary, while the southern provinces passed to the Fatimid Caliphate after its conquest of Egypt in 969. The division of Syria into northern and southern parts would persist, despite political changes, until the Mamluk conquest in the late 13th century.

Administrative divisions of the Diocese of the East (Byzantine Syria)

The junds were an adaptation of the preexisting administrative system of the Diocese of the East (Byzantine Syria) to suit the nascent Muslim state's needs.[11] The Byzantine system, in turn, had been based on that instituted by its Roman predecessor in the aftermath of the First Jewish Revolt in 70 CE and the Bar Kokhba Revolt in 135 CE. To establish closer control over the broadly spread population of Syria following the revolts, the region was subdivided into smaller units centered around an urban center which policed and collected taxes from the surrounding hinterland.[12] By 400 the southern half of Syria was divided between the three Palestines (Palaestina Prima, Palaestina Secunda, and Palaestina Tertia), Phoenice and Arabia.[13]

Following the decisive Muslim victory at Yarmouk in 636, and the occupation of most of the Mediterranean coast and northern Syria in the next two years, the Muslims began to militarily and administratively organize the region for their needs.[14] Caliph Umar, who ruled from Medina, visited the Muslim army's principal camp at Jabiya, the former Ghassanid capital, at least once between 637 and 639.[15] From there he personally oversaw the distribution of allowances (ata) and rations (rizq) to the Muslim soldiery, tax collection from the conquered population, and the appointments to military command. There may have been initial Muslim intentions to establish Jabiya as the permanent, central garrison town of Syria along the lines of those later established in the conquered regions of Iraq (Kufa and Basra), Egypt (Fustat), and Ifriqiya (Kairouan).[14] Those garrison cities developed into major urban centers of the Caliphate. During one of his visits, or by 640 at the latest, the central army camp at Jabiya was disbanded by Umar.[16] Instead, as a result of several factors, "a self-supporting, more flexible" military-administrative system was established, according to the historian Alan Walmsley.[16]

Unlike Iraq and Egypt where settlement was concentrated along the major rivers of those provinces, Syrian settlement was distributed over an extensive area of mountains, valleys, and plains. The complex geography slowed communications and army movements in the region, necessitating multiple regional centers for efficient administration and defense;[17] according to Walmsley, this was "a principle confirmed by over 500 years of Roman and Byzantine administration".[17] The change of Muslim military objectives following Yarmouk, when focus shifted to the northern Syrian and Mediterranean fronts, also necessitated the establishment of additional army headquarters and garrisons, such as Homs, diminishing Jabiya's centrality. Further reducing troop numbers in Jabiya was the Plague of Amwas in 639, which reduced the garrison there from 24,000 to 4,000. The decrease was likely due to factors in addition to the plague. In late 639 or early 640, a significant number of Muslim troops also left Syria for the conquest of Egypt under Amr's command.[18]

Troop numbers in Jabiya could not be restored in the aftermath of the plague and the departure of Muslim troops to other fronts. Unlike in Iraq where there were high levels of Arab tribal immigration, similar immigration into Syria was restricted by the Qurayshite elite in a bid to preserve their pre-established interests in the region.[19] Syria had a substantial, long-standing Arab population, both in the tribes who dominated the steppe and formerly served Byzantium and in the urban Arab communities, particularly those of Damascus and Homs.[20] Not long after Yarmouk, the Arab tribes of Syria were incorporated into the nascent Muslim military structure there. The native tribes had a preference for the established urban centers with which they were long familiarized.[19] Muslim settlement in the urban centers was facilitated by the wide availability of property in the cities in the wake of the conquests, as a result of the exodus of pro-Byzantine, Greek-speaking residents or in property transfers to the Muslims secured in capitulation agreements. Muslim settlement in the hinterland, on the other hand, was limited as the Aramaic-speaking peasantry remained in their villages.[20]

Umar divided Syria into the four junds of Filastin, al-Urdunn, Dimashq, and Hims. The new garrisons were assigned to the urban centers of Lydda, Tiberias, Damascus, and Homs, respectively. In effect Umar's gave his sanction of the existing military situation in Syria, where different army units operated independently on the different fronts. By establishing the junds, Umar transformed the military structures into provincial governments concerned with the taxation of the local populations and the distribution of collected money and supplies for the troops. During the caliphate of Umar's successor Uthman (r. 644–656), supplemental garrisons were established in the respective junds, especially in the coastal cities.[21]

During the reign of Mu'awiya I or Yazid I, Qinnasrin (northern Syria) and the Jazira (Upper Mesopotamia) were separated from Jund Hims and became Jund Qinnasrin.[22][23] The separation may have been a response to the influx of northern Arab (Qays and Mudar) immigrant tribesmen to Qinnasrin and the Jazira during Mu'awiya's governorship and caliphate.[22] In 692 Caliph Abd al-Malik separated the Jazira from Jund Qinnasrin, and it became the independent province of the Jazira. According to Blankinship, this change of status may have been related to the peace settlement reached with the Qays in 691 after the Qays had rebelled against the Umayyads during the Second Muslim Civil War.[24] According to the historian Hugh N. Kennedy, the separation was done at the request of Muhammad ibn Marwan, Abd al-Malik's brother and his commander responsible for the Jazira.[23]

In 786 Caliph Harun al-Rashid established Jund al-Awasim out of the northern part of Jund Qinnasrin. It spanned frontier zone with the Byzantine Empire, extending from the areas immediately south of Antioch, Aleppo, and Manbij and eastward to the Euphrates. Manbij and later Antioch became the capitals of the new jund.[25][26] Jund al-Awasim served as the second defensive line behind the actual frontier zone, the Thughur, which encompassed the far northern Syrian towns of Baghras, Bayas, Duluk (modern Gaziantep), Alexandretta, Cyrrhus, Ra'ban and Tizin.[25][27] The Thughur was subdivided into the Cilician or Syrian al-Thughur al-Sha'miya and the Jaziran or Mesopotamian al-Thughur al-Jaziriya sectors, roughly separated by the Amanus mountains. Tarsus and Malatya were the most important towns in the Syrian and the Mesopotamian sectors respectively, though the two districts did not have administrative capitals sometimes were under the administrative control of Jund al-Awasim. By the 10th century, the terms Thughur and al-Awasim were often used interchangeably in the sources.[25][28][29]

The governor of the provinces were called wali or amir.[30]

• Jund Dimashq (جُـنْـد دِمَـشْـق, "military district of Damascus"), with its capital at Damascus,[31] was the largest of the provinces and encompassed much of present-day Lebanon and territories east of the Jordan River known as the al-Balqa region.[32]
• Jund Filastin (جُـنْـد فِـلَـسْـطِـيْـن, "military district of Palestine") stretched from Aqaba on the Red Sea and al-'Arish in the Sinai in the south to the lower Galilee in the north,[33] encompassing most of the territory of the Byzantine provinces of Palaestina Prima and Palaestina Tertia.[34] The Tulunids expanded the province eastwards and southwards, at the expense of Jund Dimasq, to include regions in modern-day southern Jordan and north-western Saudi Arabia.[35] Ramla was founded in 715 and became both the administrative capital and most important city in Palestine.[36]
• Jund al-Urdunn (جُـنْـد الْأُرْدُنّ, "military district of the Jordan") corresponded with Palaestina Secunda and covered most of the Galilee and the western part of Peraea in Transjordan.[37] It also included the cities Acre and Tyre on the coast.[38] Tabariyyah (Tiberias) replaced Scythopolis as the new capital of the province.[39]
• Jund Hims (جُـنْـد حِـمْـص, "military district of Homs"), with its capital at Homs.[31]
• Jund Qinnasrin (جُـنْـد قِـنَّـسْـرِيْـن, "military district of Qinnasrin"), with its capital at Qinnasrin,[31] was carved out of the northern part of Jund Hims.
