The Battle of Heliopolis or Ayn Shams was a decisive battle between Arab Muslim armies and Byzantine forces for the control of Egypt. Though there were several major skirmishes after this battle, it effectively decided the fate of the Byzantine rule in Egypt, and opened the door for the Muslim conquest of the Byzantine Exarchate of Africa.
At the time of the death of Muhammad on 8 June 632, Islam had effectively unified the entire Arabian peninsula. Within the next twelve years, under the rule of the first two Caliphs an Islamic empire arose that annexed all of what used to be the Sassanid Empire, and most of the eastern provinces of the Byzantine Empire. The Muslim Caliphate continued to expand until by the turn of the 8th-century, it stretched from the Atlantic Ocean in the west to Central Asia in the east.
Under the first Caliph, Abu Bakr, force was used to prevent unrest and rebellion from causing the collapse of the new Islamic state, and the first raids were carried out into the territory of the Sassanid Empire. But the all-out attack on the neighboring empires came with the ascension of the second Caliph, Umar. When the new Caliph began his rule in 634, the international situation in the Middle East could hardly have been more propitious for a new and ambitious power: the region's two traditional main powers, the Byzantine and the Sassanid Empires, had exhausted each other in a conflict that raged for over 20 years. By the 630s, Sassanid Persia had descended into a state of civil war, while Byzantium, under the aging emperor Heraclius, its manpower and resources depleted in the struggle with its old adversary, was struggling to re-establish its authority in its newly re-conquered eastern provinces. The two states were thus in considerable internal turmoil, and unable to either stop the Muslim expansion or to recover from its first blows. It is unknown whether Umar intended from the outset to conquer both the Sassanid and the Byzantine Empire, or simply allowed raids, and then, perceiving their weakness, followed up with full-scale invasion.[1]
After successfully conquering Syria between 634 and 638, the Arabs turned their attention to Egypt. The attack on Africa took the Byzantines by surprise. Heraclius's generals had advised him that the Muslims would need a generation to digest Persia before undertaking another wholesale conquest. The increasingly frail Emperor was forced to depend on his generals, and the result was complete disaster.[2][pageneeded]
In 639, less than a year after the complete fall of the Sassanid Empire, an army of some 4,000 commanded by Amr ibn al-A'as, under orders of Omar, began the invasion of the Diocese of Egypt. That relatively tiny force marched from Syria through El-Arish, easily took Farama, and from there proceeded to Bilbeis, where they were delayed for a month.[3] But having captured Bilbeis, the Arabs moved again, eerily echoing Heraclius' successful campaign against the Sassanids just a short decade ago. A small force, commanded by a charismatic and tactically brilliant commander went behind enemy lines, and caused chaos all out of proportion to their size. They laid siege to the fortress of Babylon near modern Cairo, which withstood Amr's siege for seven months.[4] In the meantime Amr and his army marched (or rode) to a point on the Nile called Umm Dunein. The siege of this city caused Amr and his horsemen considerable difficulty as they lacked siege engines and overwhelming numbers. After finally taking Umm Dunein, Amr crossed the Nile to Faiyum. There, on 6 June 640, a second army dispatched by Omar arrived at Heliopolis (the modern Ain Shams) and began to lay siege to it. Amr retraced his route across the Nile River, and united his forces with those of the second army. They began to prepare for movement towards Alexandria – but scouts reported the approach of the Byzantine army.[5]
The battle
At that point the united Arab army was confronted by a Roman army, which Amr, who had taken overall command, defeated at the Battle of Heliopolis. Just as Byzantine generals had failed in Syria, they did in Egypt, and the Empire's economically most valuable province after Anatolia was lost. The battle took place sometime in early to mid July 640, near the ancient city of Heliopolis, with Arab forces totaling approximately 15,000 under the command of Amr ibn al-A'as, and the Byzantine forces estimated at well over 20,000 under Theodore, commander of all Byzantine forces in Egypt.[6]
The Byzantine army could have responded sooner, but had not, for reasons that will never be known.[7] Though historians such as Butler blame the treachery of the Coptic Christians as well as the failure of the Byzantine generals for the swift fall of the Exarchate of Egypt, Gibbon does not blame anyone as much as he praises the character and genius of Amr for the victory at Heliopolis. Gibbon says "the conquest of Egypt may be explained by the character of the victorious Saracen, one of the first of his nation."
Whether through the foolishness of the Byzantine generals, including Theodore, contributed to what then occurred, certainly Amr fought a brilliant battle at Heliopolis. When the Byzantine army began approaching, Amr divided his army into three separate units, with one detachment under the command of a trusted commander, Kharija. This unit marched abruptly east to nearby hills, where they effectively hid. This unit was to remain there until the Romans had begun the battle, at which point they were to fall on the Roman flank or rear, whichever was more vulnerable. The second detachment Amr ordered to the south, which would be the direction the Romans would flee if the battle went badly. Once the Byzantine forces initiated contact with Amr's forces and commenced an attack, the detachment of Kharija attacked the Byzantine rear, which was completely unexpected by the Romans. Theodore had not kept scouts out, or, if he had, he ignored their warning of the approaching Arab horsemen. This attack from the rear created utter chaos among the Byzantine ranks. As Theodore's troops attempted to flee to the south, they were attacked by the third detachment, which had been placed there for just such a purpose. This completed the final break-down and defeat of the Byzantine army, which fled in all directions.[6][7]
Theodore survived, but with only a tiny fragment of his army, while the remainder was killed or captured. In the battle's aftermath, most of southern and central Egypt fell to Amr's forces. The defeat at Heliopolis was crucial, as it removed the last Roman force standing between the Islamic invaders and the heart of Egypt. However, not only did the Battle of Heliopolis leave Egypt practically defenceless, it also encouraged the disaffected natives, most of whom were Monophysite Christians and had suffered on-and-off persecution at the hands of Constantinople, to rise up against their Roman oppressors. Although the Byzantine Empire was certainly by lineage the Roman Empire, its traditions, language, and ruling elite, by this time, were Greek. The Greeks of Egypt, whose numbers could scarcely equal a tenth of the native population, were overwhelmed by the universal defection of those same natives from obedience to the Roman Empire. As Bury wrote in the History of the Later Roman Empire from Arcadius to Irene:
”The Greeks had ever been hated, they were no longer feared: the magistrate fled from his tribunal, the bishop from his altar; and the distant garrisons were surprised or starved by the surrounding multitudes".
Bishop John of Nikiu said, "And thereupon the Moslem made their entry into Nakius, and took possession, and finding no soldiers (to offer resistance), they proceeded to put to the sword all whom they found in the streets and in the churches, men, women, and infants, and they showed mercy to none. And after they had captured (this) city, they marched against other localities and sacked them and put all they found to the sword. And they came also to the city of Sa, and there they found Esqutaws and his people in a vineyard, and the Moslem seized them and put them to the sword.[8]
It is notable that after the end of Amr's rule in Egypt, the population found their taxes ever increasing. Indeed, under the Umayyad Caliphate the Coptic Christians of Egypt found their taxes higher than the Byzantine Greeks had ever made them.[9]
The next year and a half were spent on more maneuvers, skirmishes, and sieges before the formal surrender of the capital, Alexandria, took place on 4 November 641. But Sir Walter Scott asserts that "the fate of Byzantine Africa was decided at the Battle of Heliopolis". For the Byzantine Empire, permanently losing Egypt meant the loss of an irreplaceable source of food and money. The loss of Egypt and Syria, followed later by the conquest of the Exarchate of Africa also meant that the Mediterranean, long a "Roman lake", was now contested between two powers: the Muslim Caliphate and the Byzantines. In the event, the Byzantine Empire, although sorely tested, would be able to hold on to Anatolia, while the mighty walls of Constantinople would save it, during two great Arab sieges, from the fate of the Persian Empire.
The 630s decade ran from January 1, 630, to December 31, 639.
The 640s decade ran from January 1, 640, to December 31, 649.
Year 640 (DCXL) was a leap year starting on Saturday of the Julian calendar. The denomination 640 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
The Arab–Byzantine wars were a series of wars between a number of Muslim-Arab dynasties and the Byzantine Empire from the 7th to the 11th century. Conflict started during the initial Muslim conquests, under the expansionist Rashidun and Umayyad caliphs, in the 7th century and continued by their successors until the mid-11th century.
ʿĀmir ibn ʿAbd Allāh ibn al-Jarrāḥ, better known as Abū ʿUbayda was a Muslim commander and one of the Companions of the Islamic prophet Muhammad. He is mostly known for being one of the ten to whom Paradise was promised. He remained commander of a large section of the Rashidun Army during the time of the Rashid Caliph Umar and was on the list of Umar's appointed successors to the Rashidun Caliphate but died before Umar did.
The Arab conquest of Egypt, led by the army of 'Amr ibn al-'As, took place between 639 and 646 AD and was overseen by the Rashidun Caliphate. It ended the seven-century-long period of Roman reign over Egypt that began in 30 BC. Byzantine rule in the country had been shaken, as Egypt had been conquered and occupied for a decade by the Sasanian Empire in 618–629, before being recovered by the Byzantine emperor Heraclius. The caliphate took advantage of Byzantines' exhaustion and captured Egypt ten years after its reconquest by Heraclius.
The Muslim conquest of the Levant, or Arab conquest of Syria, 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.
Umar was the second Rashidun Caliph and reigned during 634–644. Umar's caliphate is notable for its vast conquests, aided by brilliant field commanders, he was able to incorporate present day Iraq, Iran, Azerbaijan, Armenia, Georgia, Syria, Jordan, Palestine, Lebanon, Egypt, and part of Afghanistan, Turkmenistan and south western Pakistan into the Caliphate. During his reign, the Byzantines lost more than three fourths of their territory and in Persia, and Umar was the king (ruler) of the Sassanid Empire before it ceased to exist.
The Rashidun Caliphate was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE. During its existence, the empire was the most powerful economic, cultural, and military force in West Asia.
The siege of Damascus (634) lasted from 21 August to 19 September 634 before the city fell to the Rashidun Caliphate. Damascus was the first major city of the Eastern Roman Empire to fall in the Muslim conquest of Syria.
The siege of Jerusalem (636–637) was part of the Muslim conquest of the Levant and the result of the military efforts of the Rashidun Caliphate against the Byzantine Empire in the year 636–637/38. It began when the Rashidun army, under the command of Abu Ubayda, besieged Jerusalem beginning in November 636. After six months, the Patriarch Sophronius agreed to surrender, on condition that he submit only to the Caliph. According to Islamic tradition, in 637 or 638, Caliph Umar traveled to Jerusalem in person to receive the submission of the city. The Patriarch thus surrendered to him.
Battle of Marj-ud-Debaj was fought between the Byzantine army, survivors from the conquest of Damascus, and the Rashidun Caliphate army in September 634. It was a successful raid after three days of armistice, on the Byzantine survivors of the conquest of Damascus.
Forces of the Rashidun Caliphate seized the major Mediterranean port of Alexandria away from the Eastern Roman Empire in the middle of the 7th century AD. Alexandria had been the capital of the Byzantine province of Egypt. This ended Eastern Roman maritime control and economic dominance of the Eastern Mediterranean and thus continued to shift geopolitical power further in favor of the Rashidun Caliphate.
The Battle of al-Qadisiyyah was an armed conflict which took place in 636 CE between the Rashidun Caliphate and the Sasanian Empire. It occurred during the early Muslim conquests and marked a decisive victory for the Rashidun army during the Muslim conquest of Persia.
Kharija ibn Hudhafa was a companion of Muhammad and a commander in the Muslim conquest of Egypt during the reign of Caliph Umar. He served as the chief judge and commander of the security forces in Egypt under the governor Amr ibn al-As.
Theodore was the brother of the Byzantine emperor Heraclius, a curopalates and leading general in Heraclius' wars against the Persians and against the Muslim conquest of the Levant.
ʿAmr ibn al-ʿĀṣ al-Sahmī was the Arab commander who led the Muslim conquest of Egypt and served as its governor in 640–646 and 658–664. The son of a wealthy Qurayshite, Amr embraced Islam in c. 629 and was assigned important roles in the nascent Muslim community by the Islamic prophet Muhammad. The first caliph Abu Bakr appointed Amr as a commander of the conquest of Syria. He conquered most of Palestine, to which he was appointed governor, and helped lead the Arabs to decisive victories over the Byzantines at the battles of Ajnadayn and Yarmouk in 634 and 636.
The Battle of Sufetula took place in 647 between the Arab Muslim forces of the Rashidun Caliphate and the Byzantine Exarchate of Africa.
The Babylon Fortress, a major military stronghold of the Byzantine Empire in Egypt, was captured by forces of the Rashidun Caliphate after a prolonged siege in 640. It was a major event during the Muslim conquest of Egypt.
The Battle of Marj ar-Rum, also known as the Battle of Marj Dimashq, was a conflict between the Rashidun caliphate and the Byzantine Empire. The battle occurred shortly after the Battle of Fahl when the Byzantines attempted to recapture Damascus. Heraclius, the Byzantine emperor, sent two separate forces in the effort, one army led by Theodore the Patricius and a second army led by Shannash al-Rome. The Rashidun army led by Abu Ubaydah ibn al Jarrah and Khalid ibn al-Walid was ordered to assist Yazid ibn Abi Sufyan who was acting as the garrison commander of Damascus.
