Muslim conquest of the Levant
The Muslim conquest of the Levant (Arabic: فَتْحُ الشَّام, romanized: Fath aş-Şâm; lit. "Conquest of Syria"), or Arab conquest of Syria,[1] was a 634–638 CE invasion of Byzantine Syria by the Rashidun Caliphate. A part of the wider Arab-Byzantine Wars, the Levant was brought under Arab Muslim rule and developed into the provincial region of Bilad al-Sham. Clashes between the Arabs and Byzantines on the southern Levantine borders of the Byzantine Empire had occurred during the lifetime of Muhammad, with the Battle of Muʿtah in 629 CE. However, the actual conquest did not begin until 634, two years after Muhammad's death. It was led by the first two Rashidun caliphs who succeeded Muhammad: Abu Bakr and Umar ibn al-Khattab. During this time, Khalid ibn al-Walid was the most important leader of the Rashidun army.
Rise of the Caliphate[edit]
Military confrontations with the Byzantine Empire began during the lifetime of Muhammad. The Battle of Mu'tah was fought in September 629 near the village of Mu'tah, east of the Jordan River and Karak in Karak Governorate, between the forces of the Islamic prophet Muhammad and the forces of the Byzantine Empire and their Arab Christian Ghassanid vassals. In Islamic historical sources, the battle is usually described as the Muslims' attempt to take retribution against the Ghassanids after a Ghassanid official executed Muhammad's emissary who was en route to Bosra. [7] During the battle the Muslim army was routed.[8][9] After three Muslim leaders were killed, the command was given to Khalid ibn al-Walid and he succeeded in saving the rest of the forces.[8] The surviving Muslim forces retreated to Medina.
After the Farewell Pilgrimage in 632, the Muhammad appointed Usama ibn Zayd as the commander of an expeditionary force which was to invade the region of Balqa in the Byzantine Empire. This expedition was known as the Expedition of Usama bin Zayd and its stated aim was to avenge the Muslim losses at the Battle of Mu'tah, in which Usama's father and Muhammad's former adopted son, Zayd ibn Harithah, had been killed.[10] Usama's expedition in May/June 632 was successful and his army was the first Muslim force to successfully invade and raid Byzantine territory.
Muhammad died in June 632, and Abu Bakr was appointed Caliph and political successor at Medina. Soon after Abu Bakr's succession, several Arab tribes revolted against him in the Ridda wars (Arabic for the Wars of Apostasy). The Campaign of the Apostasy was fought and completed during the eleventh year of the Hijri. The year 12 Hijri dawned, on 18 March 633, with Arabia united under the central authority of the Caliph at Medina.
Whether Abu Bakr intended a full-out imperial conquest or not is hard to say; he did, however, set in motion a historical trajectory that in just a few short decades would lead to one of the largest empires in history, starting with a confrontation with the Persian Empire under the general Khalid ibn al-Walid.
After successful campaigns against the Sassanids and the ensuing conquest of Iraq, Khalid established his stronghold in Iraq. While engaged with Sassanid forces, he also confronted the Ghassanids, Arab clients of the Byzantines. Medina soon recruited tribal contingents from all over the Arabian peninsula. Only those who had rebelled during the Ridda wars were excluded from the summons and remained excluded from Rashidun armies until 636, when Caliph Umar fell short of manpower for the Battle of Yarmouk and the Battle of al-Qādisiyyah. The tradition of raising armies from tribal contingents remained in use until 636, when Caliph Umar organised the army as a state department.
Abu Bakr organised the army into four corps, each with its own commander and objective.
Not knowing the precise position of the Byzantine army, Abu Bakr ordered that all corps should remain in touch with each other so that they could render assistance if the Byzantines were able to concentrate their army in any operational sector. In case the corps had to concentrate for one major battle, Abu Ubaidah was appointed Commander-in-Chief of the entire army.[11]
In the first week of April 634, the Muslim forces began to move from their camps outside Medina. The first to leave was Yazid's corps, followed by Shurahbil, Abu Ubaidah and Amr, each a day's march from the other.
Abu Bakr walked for a short distance by the side of each corps commander. His parting words which he repeated to each of the corps commanders, were as follows:
