Under the last of the Umayyads
, the Arabian empire extended two hundred days journey from east to west, from the confines of Tartary
and India to the shores of the Atlantic Ocean
... We should vainly seek the indissoluble union and easy obedience that pervaded the government of Augustus
and the Antonines
; but the progress of Islam
diffused over this ample space a general resemblance of manners and opinions. The language and laws of the Quran
were studied with equal devotion at Samarcand
: the Moor
and the Indian
embraced as countrymen and brothers in the pilgrimage
; and the Arabian language
was adopted as the popular idiom in all the provinces to the westward of the Tigris
The Muslim conquests brought about the collapse of the Sassanid Empire
and a great territorial loss for the Byzantine Empire
. The reasons for the Muslim success are hard to reconstruct in hindsight, primarily because only fragmentary sources from the period have survived. Fred McGraw Donner
suggests that formation of a state in the Arabian peninsula and ideological (i.e., religious) coherence and mobilization was a primary reason why the Muslim armies
in the space of a hundred years were able to establish one of the largest pre-modern empires
until that time. Estimates of the total area of the combined territory held by the Islamic Caliphate at its peak have been as high as thirteen million square kilometers, or five million square miles.
Most historians agree as well that the Sassanid Persian and Byzantine Roman empires were militarily and economically exhausted from decades of fighting one another
Byzantine and Sasanian Empires in 600 AD
Arabia was a region that hosted a number of different cultures, some urban and others nomadic Bedouin.
Arabian society was divided along tribal and clan lines with the most important divisions being between the "southern" and "northern" tribal associations.
Both the Roman and Persian empires competed for influence in Arabia by sponsoring clients, and in turn Arabian tribes sought the patronage of the two rival empires to bolster their own ambitions.
The Lakhmid kingdom which covered parts of what is now southern Iraq and northern Saudi Arabia was a client of Persia, and in 602 the Persians deposed the Lakhmids to take over the defense of the southern frontier themselves.
This left the Persians exposed and over-extended, helping to set the stage for the collapse of Persia later that century.
Southern Arabia, especially what is now Yemen, had for thousands of years been a wealthy region that had been a center of the spice trade.
Yemen had been at the center of an international trading network linking Eurasia to Africa and Yemen had been visited by merchants from East Africa, Europe, the Middle East, India and even from as far away as China.
In turn, the Yemeni were great sailors, travelling up the Red Sea to Egypt and across the Indian Ocean to India and down the east African coast.
Inland, the valleys of Yemen had been cultivated by a system of irrigation that had been set back when the Marib Dam was destroyed by an earthquake in about 450 AD.
Frankincense and myrrh had been greatly valued in the Mediterranean region, being used in religious ceremonies. However, the conversion of the Mediterranean world to Christianity had significantly reduced the demand for these commodities, causing a major economic slump in southern Arabia which helped to create the impression that Arabia was a backward region.
Little is known of the pre-Islamic religions of Arabia, but it is known that the Arabs worshipped a number of gods such as al-Lat, Manat, al-Uzza and Hubal, with the most important being Allah (God).
There were also Jewish and Christian communities in Arabia and aspects of Arab religion reflected their influence.
Pilgrimage was a major part of Arabian paganism, and one of the most important pilgrimage sites was Mecca, which housed the Kaaba, considered an especially holy place to visit.
Mohammad, a merchant of Mecca, started to have visions in which he claimed that the Archangel Gabriel had told him that he was the last of the prophets continuing the work of Jesus Christ and the prophets of Tanakh
After coming into conflict with the elite of Mecca, Mohammad fled to the city of Yathrib, which was renamed Medina.
At Yathrib, Mohammad founded the first Islamic state and by 630 conquered Mecca.
Arab conquests of the Sassanid Empire and Syria 620-630
The prolonged and escalating Byzantine–Sassanid
wars of the 6th and 7th centuries and the recurring outbreaks of bubonic plague (Plague of Justinian
) left both empires exhausted and weakened in the face of the sudden emergence and expansion of the Arabs. The last of these wars ended with victory for the Byzantines: Emperor Heraclius
regained all lost territories, and restored the True Cross
The war against Zoroastrian Persia, whose people worshiped the fire god Ahura Mazda, had been portrayed by Heraclius as a holy war in defense of the Christian faith and the Wood of the Holy Cross, as splinters of wood said to be from the True Cross were known, had been used to inspire Christian fighting zeal.
The idea of a holy war against the "fire worshipers", as the Christians called the Zoroastrians, had aroused much enthusiasm, leading to an all-out effort to defeat the Persians.
Nevertheless, neither empire was given any chance to recover, as within a few years they were overrun by the advances of the Arabs
(newly united by Islam), which, according to James Howard-Johnston, "can only be likened to a human tsunami".
According to George Liska, the "unnecessarily prolonged Byzantine–Persian conflict opened the way for Islam".
In late 620s Muhammad
had already managed to conquer and unify much of Arabia
under Muslim rule, and it was under his leadership that the first Muslim-Byzantine skirmishes took place in response to Byzantine incursions. Just a few months after Heraclius and the Persian general Shahrbaraz
agreed on terms for the withdrawal of Persian troops from occupied Byzantine eastern provinces in 629, Arab and Byzantine troops confronted each other at the Battle of Mu'tah
as a result of Byzantine vassals murdering a Muslim emissary. Muhammad
died in 632 and was succeeded by Abu Bakr
, the first Caliph
with undisputed control of the entire Arab peninsula after the successful Ridda Wars
, which resulted in the consolidation of a powerful Muslim state throughout the peninsula.
Byzantine sources, such as the Short History written by Nikephoros
, claim that the Arab invasion came about as a result of restrictions imposed on Arab traders curtailing their ability to trade within Byzantine territory, and to send the profits of their trade out of Byzantine territory. As a result, the Arabs murdered a Byzantine official named Sergius whom they held responsible for convincing the Emperor Heraclius to impose the trade restrictions. Nikephoros relates that:
The Saracens, having flayed a camel, enclosed him in the hide and sewed it up. As the skin hardened, the man who was left inside also withered and so perished in a painful manner. The charge against him was that he had persuaded Heraclius not to allow the Saracens to trade from the Roman country and send out of the Roman state the thirty pounds of gold which they normally received by way of commercial gain; and for this reason they began to lay waste the Roman land.
Some scholars assert that this is the same Sergius, called "the Candidatus", who was "killed by the Saracens" as related in the 7th century Doctrina Jacobi
In Arabia, swords from India were greatly esteemed as being made of the finest steel, and were the favorite weapons of the Mujahideen
The Arab sword known as the sayfy
closely resembled the Roman gladius
Swords and spears were the major weapons of the Muslims and armour was either mail or leather.
In northern Arabia, Roman influence predominated, in eastern Arabia, Persian influence predominated and in Yemen, Indian influence was felt.
As the caliphate spread, the Muslims were influenced by the peoples they conquered--the Turks in Central Asia, the Persians, and the Romans in Syria.
The Bedouin tribes of Arabia favored archery, though, contrary to popular belief, Bedouin archers usually fought on foot instead of horseback.
The Arabs usually fought defensive battles with their archers placed on both flanks.
By the Umayyad period, the caliphate had a standing army, including the elite Ahl al-Sham
("people of Syria"), raised from the Arabs who settled in Syria.
The caliphate was divided into a number of jund
, or regional armies, stationed in the provinces being made of mostly Arab tribes who were paid monthly by the Diwan al-Jaysh
The infantry of the Roman Army continued to be recruited from within the empire, but much of the cavalry were either recruited from "martial" peoples in the Balkans or in Asia Minor, or, alternatively, were Germanic mercenaries.
Most of the Roman troops in Syria were indigenae
(local) and it seems that at the time of the Muslim conquest, the Roman forces in Syria were Arabs.
In response to the loss of Syria, the Romans developed the phylarch
system of using Armenian and Christian Arab auxiliaries living on the frontier to provide a "shield" to counter raiding by the Muslims into the empire.
Overall, the Roman Army remained a small, but professional force of foederati
Unlike the foederati
who were sent where they were needed, the stradioti
lived in the frontier provinces.
The most famous of these units was the Varangian Guard
made up of Vikings.
During the last decades of the Sasanian empire, the frequent use of royal titles by Persian governors in Central Asia, especially in what is now Afghanistan, indicates a weakening of the power of the Shahinshah
(King of Kings), suggesting the empire was already breaking down at the time of the Muslim conquest.
Persian society was rigidly divided into castes with the nobility being of supposed "Aryan" descent, and this division of Persian society along caste lines was reflected in the military.
aristocracy provided the cavalry, the paighan
infantry came from the peasantry and most of the greater Persian nobility had slave soldiers, this last being based on the Persian example.
Much of the Persian army consisted of tribal mercenaries recruited from the plains south of the Caspian Sea and from what is now Afghanistan.
The Persian tactics were cavalry based with the Persian forces usually divided into a center, based upon a hill, and two wings of cavalry on either side.
Little is known about the military forces of the Christian state of Ethiopia other than that they were divided into sarawit
professional troops and the ehzab
The Ethiopians made much use of camels and elephants.
The Berber peoples of North Africa had often served as a federates
(auxiliaries) to the Roman Army.
The Berber forces were based around the horse and camel, but seemed to have hampered by a lack of weapons or protection with both Roman and Arab sources mentioning the Berbers lacked armour and helmets.
The Berbers went to war with their entire communities and the presence of women and children both slowed down the Berber armies and tied down Berber tribesmen who tried to protect their families.
The British historian David Nicolle called the Turkish peoples of Central Asia the "most formidable foes" faced by the Muslims.
The Jewish Turkish Khazar khanate
, based in what is now southern Russia and Ukraine, had a powerful heavy cavalry.
The Turkish heartland of Central Asia was divided into five khanates whose khans variously recognized the shahs of Iran or the emperors of China as their overlords.
Turkish society was feudal with the khans only being pater primus
among the aristocracy of dihquans
who lived in castles in the countryside, with the rest of Turkish forces being divided into kadivar
(servants) and atbai
The heavily armored Turkish cavalry were to play a great role in influencing subsequent Muslim tactics and weapons; the Turks, who were mostly Buddhists at the time of the Islamic conquest, were converted to Islam and, ironically, the Turks came to be regarded as the foremost Muslim warriors, to the extent of replacing the Arabs as the dominant peoples in the Dar-al-Islam
(House of Islam).
During the migration period
, the Germanic Visigoths had traveled from their homeland north of the Danube to settle in the Roman province of Hispania, creating a kingdom upon the wreckage of the Western Roman empire.
The Visigothic state in Iberia was based around forces raised by the nobility whom the king could call out in the event of war.
The king had his gardingi
loyal to himself, while the nobility had their bucellarii
The Visigoths favored cavalry with their favorite tactics being to repeatedly charge a foe combined with feigned retreats.
The Muslim conquest of most of Iberia in less than a decade does suggest serious deficiencies with the Visigothic kingdom, though the limited sources make it difficult to discern the precise reasons for the collapse of the Visigoths.
Another Germanic people who founded a state upon the ruins of the Western Roman empire were the Franks who settled in Gaul, which came to be known afterwards as France.
Like the Visigoths, the Frankish cavalry played a "significant part" in their wars.
The Frankish kings expected all of their male subjects to perform three months of military service every year, and all serving under the king's banner were paid a regular salary.
Those called up for service had to provide their own weapons and horses, which contributed to the "militarisation of Frankish society".
At least part of the reason for the victories of Charles Martel
was he could call up a force of experienced warriors when faced with Muslim raids.
Conquest of the Levant: 634–641
The province of Syria was the first to be wrested from Byzantine
control. Arab-Muslim raids that followed the Ridda wars
prompted the Byzantines to send a major expedition into southern Palestine
, which was defeated by the Arab forces under command of Khalid ibn al-Walid
at the Battle of Ajnadayn
Ibn al-Walid, had converted to Islam around 627, becoming one of Muhammad's most successful generals.
Ibn al-Walid had been fighting in Iraq against the Persians when he led his force on a trek across the deserts to Syria to attack the Romans from the rear.
In the "Battle of the Mud" fought outside of Pella in the Jordan river valley in January 635 the Arabs won another victory.
After a siege of six months the Arabs took Damascus, but Emperor Heraclius later retook it.
At the battle of Yarmuk between 16–20 August 636, the Arabs were victorious, defeating Heraclius.
Ibn al-Walid appears to have been the "real military leader" at Yarmuk "under the nominal command of others".
Syria was ordered to be abandoned to the Muslims with Heraclius reportedly saying: "Peace be with you Syria; what a beautiful land you will be for your enemy".
On the heels of their victory, the Arab armies took Damascus
again in 636, with Baalbek
, and Hama
to follow soon afterwards.
However, other fortified towns continued to resist despite the rout of the imperial army and had to be conquered individually.Jerusalem
fell in 638, Caesarea
in 640, while others held out until 641.
Arab campaigns in Anatolia 637–638
After a two-year siege, the garrison of Jerusalem surrendered rather than starve to death; under the terms of the surrender Caliph Umar promised to tolerate the Christians of Jerusalem and not to turn churches into mosques.
True to his word, the Caliph Umar allowed the Church of the Holy Sepulchre to remain, with the caliph praying on a prayer rug outside of the church.
The loss to the Muslims of Jerusalem, the holiest city to Christians, proved to be the source of much resentment in Christendom. The city of Caesarea Maritima continued to withstand the Muslim siege--as it could be supplied by sea--until it was taken by assault in 640.
In the mountains of Asia Minor, the Muslims enjoyed less success, with the Romans adopting the tactic of "shadowing warfare" — refusing to give battle to the Muslims, while the people retreated into castles and fortified towns when the Muslims invaded; instead, Roman forces ambushed Muslim raiders as they returned to Syria carrying plunder and people they had enslaved.
In the frontier area where Anatolia met Syria, the Roman state evacuated the entire population and laid waste to the countryside, creating a "no-man's land" where any invading army would find no food.
For decades afterwards, a guerrilla war was waged by Christians in the hilly countryside of north-western Syria supported by the Romans.
At the same time, the Romans began a policy of launching raids via sea on the coast of the caliphate with the aim of forcing the Muslims to keep at least some of their forces to defend their coastlines, thus limiting the number of troops available for an invasion of Anatolia.
Unlike Syria with its plains and deserts — which favored the offensive — the mountainous terrain of Anatolia favored the defensive, and for centuries afterwards, the line between Christian and Muslim lands ran along the border between Anatolia and Syria.
Conquest of Egypt: 639–642
The Byzantine Empire
after the Arabs conquered the provinces of Syria and Egypt c. 650
province of Egypt held strategic importance for its grain production, naval yards, and as a base for further conquests in Africa.
The Muslim general 'Amr ibn al-'As
began the conquest of the province on his own initiative in 639.
The majority of the Roman forces in Egypt were locally-raised Coptic forces, intended to serve more as a police force; since the vast majority of Egyptians lived in the Nile river valley, surrounded on both the eastern and western sides by desert, Egypt was felt to be a relatively secure province.
In December 639, al-'As entered the Sinai with a large force and took Pelusium, on the edge of the Nile river valley, and then defeated a Roman counter-attack at Bibays.
Contrary to expectations, the Arabs did not head for Alexandria, the capital of Egypt, but instead for a major fortress known as Babylon located at what is now Cairo.
Al-'As was planning to divide the Nile river valley in two.
The Arab forces won a major victory at the Battle of Heliopolis
(640), but they found it difficult to advance further because major cities in the Nile Delta were protected by water and because al-'As lacked the machinery to break down city fortifications.
The Arabs laid siege to Babylon, and its starving garrison surrendered on 9 April 641.
Nevertheless, the province was scarcely urbanized and the defenders lost hope of receiving reinforcements from Constantinople
when the emperor Heraclius
died in 641.
Afterwards, the Arabs turned north into the Nile delta and laid siege to Alexandria.
The last major center to fall into Arab hands was Alexandria
, which capitulated in September 642.
According to Hugh Kennedy
, "Of all the early Muslim conquests, that of Egypt was the swiftest and most complete. [...] Seldom in history can so massive a political change have happened so swiftly and been so long lasting."
In 644, the Arabs suffered a major defeat by the Caspian Sea when an invading Muslim army was almost wiped out by the cavalry of the Khazar Khanate
, and, seeing a chance to take back Egypt, the Romans launched an amphibious attack which took back Alexandria for a short period of time.
Though most of Egypt is desert, the Nile river valley has some of the most productive and fertile farmland in the entire world, which had made Egypt the "granary" of the Roman empire.
Control of Egypt meant that the caliphate could weather droughts without the fear of famine, laying the basis for the future prosperity of the caliphate.
The War at Sea
Map of the main Byzantine-Muslim naval operations and battles in the Mediterranean
The Roman empire had traditionally dominated the Mediterranean and the Black Sea with major naval bases at Constantinople, Acre, Alexandria and Carthage.
In 652, the Arabs won their first victory at sea off Alexandria, which was followed by the temporary Muslim conquest of Cyprus.
As Yemen had been a center of maritime trade, Yemeni sailors were brought to Alexandria to start building an Islamic fleet for the Mediterranean.
The Muslim fleet was based in Alexandria and used Acre, Tyre and Beirut as its forward bases.
The core of the fleet's sailors were Yemeni, but the shipwrights who built the ships were Iranian and Iraqi.
In the "Battle of the Masts" off Cape Chelidonia in Anatolia in 655, the Muslims defeated the Roman fleet in a series of boarding actions.
As a result, the Romans began a major expansion of their navy, which was matched by the Arabs, leading to a naval arms race.
From the early 8th century onward, the Muslim fleet would launch annual raids on the coastline on the Roman empire in Anatolia and Greece.
As part of the arms race, both sides sought new technology to improve their warships. The Muslim warships had a larger forecastle, which was used to mount a stone-throwing engine.
The Romans invented "Greek fire", an incendiary weapon that led the Muslims to cover their ships with water-soaked cotton.
A major problem for the Muslim fleet was the shortage of timber, which led the Muslims to seek qualitative instead of quantitative superiority by building bigger warships.
To save money, the Muslim shipwrights switched from the hull-first method of building ships to the frame-first method.
Conquest of Mesopotamia and Persia: 633–651
Sasanian weaponry, 7th century
After an Arab incursion into Sasanian territories, the energetic shah
(king) Yazdgerd III
, who had just ascended the Persian throne, raised an army to resist the conquerors.
Many of the marzbans
refused to come out to help the shahinshah
However, the Persians suffered a devastating defeat at the Battle of al-Qadisiyyah
Little is known about the Battle of al-Qadisiyyah other than it lasted for several days by the banks of the river Euphrates in what is now Iraq and ended with the Persian force being annihilated.
Abolishing the Lakhmid Arab buffer state had forced the Persians to take over the desert defense themselves, leaving them overextended.
As a result of al-Qadisiyyah, the Arab-Muslims gained control over the whole of Iraq, including Ctesiphon
, the capital city of the Sassanids.
The Persians lacked sufficient forces to make use of the Zagros mountains to stop the Arabs, having lost the prime of their army at al-Qadisiyyah.
The Persian forces withdrew over the Zagros mountains
and the Arab army pursued them across the Iranian plateau, where the fate of the Sasanian empire was sealed at the Battle of Nahavand
The crushing Muslim victory at Nahavand is known in the Muslim world as the "Victory of Victories".
After Nahavand, the Persian state collapsed with Yezdegird fleeing further east and various marzbans
bending their knees in submission to the Arabs.
As the conquerors slowly covered the vast distances of Iran punctuated by hostile towns and fortresses, Yazdgerd III retreated, finally taking refuge in Khorasan
, where he was assassinated by a local satrap
In the aftermath of their victory over the imperial army, the Muslims still had to contend with a collection of militarily weak but geographically inaccessible principalities of Persia.
It took decades to bring them all under control of the caliphate.
In what is now Afghanistan--a region where the authority of the shah
was always disputed--the Muslims met fierce guerrilla resistance from the militant Buddhist tribes of the region.
Ironically, despite the complete Muslim triumph over Iran as compared to the only partial defeat of the Roman empire, the Muslims borrowed far more from the vanished Sassanian state than they ever did from the Romans.
However, for the Persians the defeat remained bitter. Some 400 years later, the Persian poet Ferdowsi
wrote in his popular poem Shahnameh
(Book of Kings
"Damn this world, damn this time, damn this fate,
That uncivilized Arabs have come to
Make me a Muslim
Where are your valiant warriors and priests
Where are your hunting parties and your feats?
Where is that warlike mien and where are those
Great armies that destroyed our county's foes?
Count Iran as a ruin, as the lair
Of lions and leopards.
Look now and despair".
The end of the Rashidun conquests
Right from the start of the caliphate, it was realized that there was a need to write down the sayings and story of Muhammad, which had been memorized by his followers before they all died.
Most people in Arabia were illiterate and the Arabs had a strong culture of remembering history orally.
To preserve the story of Mohammad and to prevent any corruptions from entering the oral history, the Caliph 'Abu Bakr had ordered scribes to write down the story of Mohammad as told to them by his followers, which was the origin of the Koran.
Disputes had emerged over which version of the Koran was the correct one and, by 644, different versions of the Koran were accepted in Damascus, Basra, Hims, and Kufa.
To settle the dispute, the Caliph 'Uthman had proclaimed the version of the Koran possessed by one of Mohammad's widows, Hafsa, to be the definitive and correct version, which offended some Muslims who held to the rival versions.
This, together with the favoritism shown by 'Uthman to his own clan, the Banu Umayya, in government appointments, led to a mutiny in Medina in 656 and 'Uthman's murder.
'Uthman's successor as Caliph, Mohammad's son-in-law, Ali, was faced with a civil war, known to Muslims as the fitna
, when the governor of Syria, Mu'awiya Ibn Abi Sufyan, revolted against him.
During this time, the first period of Muslim conquests stopped, as the armies of Islam turned against one another.
A fundamentalist group known as the Kharaji
decided to end the civil war by assassinating the leaders of both sides.
However, the fitna
ended in January 661 when the Caliph Ali was killed by a Kharaji
assassin, allowing Mu'awiya to become Caliph and found the Umayyad dynasty.
also marked the beginning of the split between Shia
Muslims, who supported Ali, and Sunni
Muslims, who opposed him.
Mu'awiya moved the capital of the caliphate from Medina to Damascus, which had a major effect on the politics and culture of the caliphate.
Mu'awiya followed the conquest of Iran by invading Central Asia and trying to finish off the Roman Empire by taking Constantinople.
In 670, a Muslim fleet seized Rhodes and then laid siege to Constantinople.
Nicolle wrote the siege of Constantinople from 670 to 677 was "more accurately" a blockade rather than a siege proper, which ended in failure as the "mighty" walls built by the Emperor Theodosius II in the 5th century AD proved their worth.
The majority of the people in Syria remained Christian, and a substantial Jewish minority remained, as well; both communities were to teach the Arabs much about science, trade and the arts.
The Umayyad caliphs are well-remembered for sponsoring a cultural "golden age" in Islamic history--for example, by building the Dome of the Rock
in Jerusalem, and for making Damascus into the capital of a "superpower" that stretched from Portugal to Central Asia, covering the vast territory from the Atlantic Ocean to the borders of China.
Explanations for the success of the early conquests
The rapidity of the early conquests has received various explanations.
Contemporary Christian writers conceived them as God's punishment visited on their fellow Christians for their sins.
Early Muslim historians viewed them as a reflection of the religious zeal of the conquerors and evidence of divine favor.
The theory that the conquests are explainable as an Arab migration triggered by economic pressures enjoyed popularity early in the 20th century, but has largely fallen out of favor among historians, especially those who distinguish the migration from the conquests that preceded and enabled it.
There are indications that the conquests started as initially disorganized pillaging raids launched partly by non-Muslim Arab tribes in the aftermath of the Ridda wars
, and were soon extended into a war of conquest by the Rashidun caliphs
although other scholars argue that the conquests were a planned military venture already underway during Muhammad's lifetime. Fred Donner
writes that the advent of Islam "revolutionized both the ideological bases and the political structures of the Arabian society, giving rise for the first time to a state capable of an expansionist movement."
According to Chase F. Robinson, it is likely that Muslim forces were often outnumbered, but, unlike their opponents, they were fast, well coordinated and highly motivated.
Another key reason was the weakness of the Byzantine and Sasanian empires, caused by the wars they had waged against each other in the preceding decades with alternating success.
It was aggravated by a plague that had struck densely populated areas and impeded conscription of new imperial troops, while the Arab armies could draw recruits from nomadic populations.
The Sasanian empire, which had lost the latest round of hostilities with the Byzantines, was also affected by a crisis of confidence, and its elites suspected that the ruling dynasty had forfeited the favor of the gods.
The Arab military advantage was increased when Christianized Arab tribes who had served imperial armies as regular or auxiliary troops switched sides and joined the West Arabian coalition.
Arab commanders also made liberal use of agreements to spare lives and property of inhabitants in case of surrender and extended exemptions from paying tribute to groups who provided military services to the conquerors.
Additionally, the Byzantine persecution of Christians opposed to the Chalcedonian creed
in Syria and Egypt alienated elements of those communities and made them more open to accommodation with the Arabs once it became clear that the latter would let them practice their faith undisturbed as long as they paid tribute.
The conquests were further secured by the subsequent large-scale migration of Arabian peoples into the conquered lands. Robert Hoyland
argues that the failure of the Sasanian empire to recover was due in large part to the geographically and politically disconnected nature of Persia, which made coordinated action difficult once the established Sasanian rule collapsed.
Similarly, the difficult terrain of Anatolia made it difficult for the Byzantines to mount a large-scale attack to recover the lost lands, and their offensive action was largely limited to organizing guerrilla operations against the Arabs in the Levant.
Conquest of Sindh: 711–714
Although there were sporadic incursions by Arab generals in the direction of India in the 660s and a small Arab garrison was established in the arid region of Makran
in the 670s,
the first large-scale Arab campaign in the Indus valley occurred when the general Muhammad bin Qasim
in 711 after a coastal march through Makran.
Three years later the Arabs controlled all of the lower Indus valley
Most of the towns seem to have submitted to Arab rule under peace treaties, although there was fierce resistance in other areas, including by the forces of Raja Dahir
at the capital city Debal
Arab incursions southward from Sindh were repulsed by the armies of Gurjara
kingdoms, and further Islamic expansion was checked by the Rashtrakuta empire
, which gained control of the region shortly after.
Conquest of the Maghreb: 647–742
Arab forces began launching sporadic raiding expeditions into Cyrenaica
(modern northeast Libya
) and beyond soon after their conquest of Egypt.
Byzantine rule in northwest Africa at the time was largely confined to the coastal plains, while autonomous Berber
polities controlled the rest.
In 670 Arabs founded the settlement of Qayrawan
, which gave them a forward base for further expansion.
Muslim historians credit the general Uqba ibn Nafi
with subsequent conquest of lands extending to the Atlantic coast, although it appears to have been a temporary incursion.
The Berber chief Kusayla
and an enigmatic leader referred to as Kahina
(prophetess or priestess) seem to have mounted effective, if short-lived resistance to Muslim rule at the end of the 7th century, but the sources do not give a clear picture of these events.
Arab forces were able to capture Carthage
in 698 and Tangiers
After the fall of Tangiers, many Berbers joined the Muslim army.
In 740 Umayyad rule in the region was shaken by a major Berber revolt
, which also involved Berber Kharijite
After a series of defeats, the caliphate was finally able to crush the rebellion in 742, although local Berber dynasties continued to drift away from imperial control from that time on.
Conquest of Hispania and Septimania: 711–721
Bilingual Latin-Arabic dinar minted in Iberia AH 98 (716/7 AD)
The Muslim conquest of Iberia
is notable for the brevity and unreliability of the available sources.
After the Visigothic
king of Spain Wittiza
died in 710, the kingdom experienced a period of political division.
The Visigothic nobility was divided between the followers of Wittiza and the new king Roderic.
Akhila, Wittiza's son, had fled to Morocco after losing the succession struggle and Muslim tradition states that he asked the Muslims to invade Spain.
Starting in the summer of 710, the Muslim forces in Morocco had launched several successful raids into Spain, which demonstrated the weakness of the Visigothic state.
Taking advantage of the situation, the Muslim Berber commander, Tariq ibn Ziyad
, who was stationed in Tangiers at the time, crossed the straits with an army of Arabs and Berbers in 711.
Most of the invasion force of 15,000 were Berbers, with the Arabs serving as an "elite" force.
Ziyad landed on the Rock of Gibraltar on 29 April 711.
After defeating the forces of king Roderic
at the river Guaddalete on 19 July 711, Muslim forces advanced, capturing cities of the Gothic kingdom one after another.
The capital of Toledo surrendered peacefully.
Some of the cities surrendered with agreements to pay tribute and local aristocracy retained a measure of former influence.
The Spanish Jewish community welcomed the Muslims as liberators from the oppression of the Catholic Visigothic kings.
In 712, another larger force of 18,000 from Morocco, led by Musa Ibn Nusayr, crossed the Straits of Gibraltar to link up with Ziyad's force at Talavera.
The invasion seemed to have entirely on the initiative of Tariq ibn Ziyad: the caliph, al-Walid, in Damascus reacted as if it was a surprise to him.
By 713 Iberia was almost entirely under Muslim control.
In 714, al-Walid summoned Ziyad to Damascus to explain his campaign in Spain, but Ziyad took his time travelling through North Africa and Palestine, and was finally imprisoned when he arrived in Damascus.
The events of the subsequent ten years, the details of which are obscure, included the capture of Barcelona
, and a raid against Toulouse
, followed by an expedition into Burgundy
The last large-scale raid to the north ended with a Muslim defeat at the Battle of Tours
at the hands of the Franks
The victory of the Franks, led by Charles Martel, over 'Abd al-Rahman Ibn 'Abd Allah al-Ghafiqi has often been misrepresented as the decisive battle that stopped the Muslim conquest of France, but the Umayyad force had been raiding Aquitaine with a particular interest in sacking churches and monasteries, not seeking its conquest.
The battle itself is a shadowy affair with the few sources describing it in poetic terms that are frustrating for the historian.
The battle occurred between 18–25 October 732 with the climax being an attack on the Muslim camp led by Martel that ended with al-Ghafiqi being killed and the Muslims withdrawing when night fell.
Martel's victory ended whatever plans there may have been to conquer France, but a series of Berber revolts in North Africa and in Spain against Arab rule may have played a greater role in ruling out conquests north of the Pyrenees.
Conquest of Transoxiana: 673–751 Transoxiana
is the region northeast of Iran
beyond the Amu Darya
or Oxus River roughly corresponding with modern-day Uzbekistan, Tajikistan, and parts of Kazakhstan. Initial incursions across the Oxus river
were aimed at Bukhara
(673) and Samarqand
(675) and their results were limited to promises of tribute payments.
In 674, a Muslim force led by Ubaidullah Ibn Zayyad attacked Bukhara, the capital of Soghdia, which ended with the Sogdians agreeing to recognize the Umayadd caliph Mu'awiaya as their overlord and to pay tribute.
In general, the campaigns in Central Asia were "hard fought" with the Buddhist Turkic peoples fiercely resisting efforts to incorporate them into the caliphate. China, which saw Central Asia as its own sphere of influence, particularly due to the economic importance of the Silk Road
, supported the Turkic defenders.
Further advances were hindered for a quarter century by political upheavals within the Umayyad caliphate
This was followed by a decade of rapid military progress under the leadership of the new governor of Khurasan
, Qutayba ibn Muslim
, which included the conquest of Bukhara and Samarqand in 706–712.
The expansion lost its momentum when Qutayba was killed during an army mutiny and the Arabs were placed on the defensive by an alliance of Sogdian
forces with support from Tang China
However, reinforcements from Syria helped turn the tide and most of the lost lands were reconquered by 741.
Muslim rule over Transoxania was consolidated a decade later when a Chinese-led army was defeated at the Battle of Talas
Before Muslim rule, the regions of Balkh
were under Sasanian rule. Further south in the Balkh region, in Bamiyan
, indication of Sasanian authority diminishes, with a local dynasty apparently ruling from late antiquity
, probably Hepthalites
subject to the Yabgu
of the Western Turkic Khaganate
. While Herat was controlled by the Sasanians, its hinterlands were controlled by northern Hepthalites who continued to rule the Ghurid
mountains and river valleys well into the Islamic era. Sistan was under Sasanian administration but Qandahar remained out of Arab hands. Kabul and Zabulistan housed Indic religions, with the Zunbils
and Kabul Shahis
offering stiff resistance to Muslim rule for two centuries until the Saffarid
Other campaigns and the end of the early conquests
In 646 a Byzantine naval expedition was able to briefly recapture Alexandria.
The same year Mu'awiya
, the governor of Syria and future founder of the Umayyad dynasty
, ordered construction of a fleet.
Three years later it was put to use in a pillaging raid of Cyprus
, soon followed by a second raid in 650 that concluded with a treaty under which Cypriots surrendered many of their riches and slaves.
In 688 the island was made into a joint dominion of the caliphate and the Byzantine empire under a pact which was to last for almost 300 years.
In 639–640 Arab forces began to make advances into Armenia, which had been partitioned into a Byzantine province
and a Sasanian province
There is considerable disagreement among ancient and modern historians about events of the following years, and nominal control of the region may have passed several times between Arabs and Byzantines.
Although Muslim dominion was finally established by the time the Umayyads acceded to power in 661, it was not able to implant itself solidly in the country, and Armenia experienced a national and literary efflorescence over the next century.
As with Armenia, Arab advances into other lands of the Caucasus
region, including Georgia
, had as their end assurances of tribute payment and these principalities retained a large degree of autonomy.
This period also saw a series of clashes with the Khazar
kingdom whose center of power was in the lower Volga
steppes, and which vied with the caliphate over control of the Caucasus.

Other Muslim military ventures were met with outright failure. Despite a naval victory over the Byzantines in 654 at the Battle of the Masts
, the subsequent attempt to besiege Constantinople
was frustrated by a storm which damaged the Arab fleet.
Later sieges of Constantinople in 668–669
(674–78 according to other estimates) and 717–718
were thwarted with the help of the recently invented Greek fire
In the east, although Arabs were able to establish control over most Sasanian-controlled areas of modern Afghanistan
after the fall of Persia, the Kabul region resisted repeated attempts at invasion and would continue to do so until it was conquered by the Saffarids
three centuries later.
By the time of the Abbasid revolution
in the middle of the 8th century, Muslim armies had come against a combination of natural barriers and powerful states that impeded any further military progress.
The wars produced diminishing returns in personal gains and fighters increasingly left the army for civilian occupations.
The priorities of the rulers also shifted from conquest of new lands to administration of the acquired empire.
Although the Abbasid era witnessed some new territorial gains, such as the conquests of Sicily
, the period of rapid centralized expansion would now give way to an era when further spread of Islam would be slow and accomplished through the efforts of local dynasties, missionaries, and traders.
Nicolle wrote that the series of Islamic conquests of the 7th and 8th centuries was "one of the most significant events in world history", leading to the creation of "a new civilisation", the Islamicised and Arabised Middle East.
Islam, which had previously been confined to Arabia, became a major world religion, while the synthesis of Arab, Roman, and Persian elements led to distinctive new styles of art and architecture emerging in the Middle East.
The military victories of armies from the Arabian Peninsula heralded the expansion of the Arabs' culture
. The conquests were followed by a large-scale migration of families and whole tribes from Arabia into the lands of the Middle East.
The conquering Arabs had already possessed a complex and sophisticated society.
Emigrants from Yemen brought with them agricultural, urban, and monarchical traditions; members of the Ghassanid
tribal confederations had experience collaborating with the empires.
The rank and file of the armies was drawn from both nomadic and sedentary tribes, while the leadership came mainly from the merchant class of the Hejaz
Two fundamental policies were implemented during the reign of the second caliph Umar
(634–44): the bedouins would not be allowed to damage agricultural production of the conquered lands and the leadership would cooperate with the local elites.
To that end, the Arab-Muslim armies were settled in segregated quarters or new garrison towns such as Basra
The latter two became the new administrative centers of Iraq and Egypt, respectively.
Soldiers were paid a stipend and prohibited from seizing lands.
Arab governors supervised collection and distribution of taxes, but otherwise left the old religious and social order intact.
At first, many provinces retained a large degree of autonomy under the terms of agreements made with Arab commanders.
As the time passed, the conquerors sought to increase their control over local affairs and make existing administrative machinery work for the new regime.
This involved several types of reorganization. In the Mediterranean region, city-states which traditionally governed themselves and their surrounding areas were replaced by a territorial bureaucracy separating town and rural administration.
In Egypt, fiscally independent estates and municipalities were abolished in favor of a simplified administrative system.
In the early eighth century, Syrian Arabs began to replace Coptic functionaries and communal levies gave way to individual taxation.
In Iran, the administrative reorganization and construction of protective walls prompted agglomeration of quarters and villages into large cities such as Isfahan
, and Qum
Local notables of Iran, who at first had almost complete autonomy, were incorporated into the central bureaucracy by the ʿAbbasid
The similarity of Egyptian and Khurasanian official paperwork at the time of the caliph al-Mansur
(754–75) suggests a highly centralized empire-wide administration.
The society of new Arab settlements gradually became stratified into classes based on wealth and power.
It was also reorganized into new communal units that preserved clan and tribal names but were in fact only loosely based around old kinship bonds.
Arab settlers turned to civilian occupations and in eastern regions established themselves as a landed aristocracy.
At the same time, distinctions between the conquerors and local populations began to blur.
In Iran, the Arabs largely assimilated into local culture, adopting the Persian language and customs, and marrying Persian women.
In Iraq, non-Arab settlers flocked to garrison towns.
Soldiers and administrators of the old regime came to seek their fortunes with the new masters, while slaves, laborers and peasants fled there seeking to escape the harsh conditions of life in the countryside.
Non-Arab converts to Islam were absorbed into the Arab-Muslim society through an adaptation of the tribal Arabian institution of clientage, in which protection of the powerful was exchanged for loyalty of the subordinates.
The clients (mawali
) and their heirs were regarded as virtual members of the clan.
The clans became increasingly economically and socially stratified.
For example, while the noble clans of the Tamim tribe
acquired Persian cavalry units as their mawali, other clans of the same tribe had slave laborers as theirs.
Slaves often became mawali of their former masters when they were freed.
Contrary to the belief of earlier historians, there is no evidence of mass conversions to Islam in the immediate aftermath of the conquests.
The first groups to convert were Christian Arab tribes, although some of them retained their religion into the Abbasid era even while serving as troops of the caliphate.
They were followed by former elites of the Sasanian empire, whose conversion ratified their old privileges.
With time, the weakening of non-Muslim elites facilitated the breakdown of old communal ties and reinforced the incentives of conversion which promised economic advantages and social mobility.
By the beginning of the eighth century, conversions became a policy issue for the caliphate.
They were favored by religious activists, and many Arabs accepted the equality of Arabs and non-Arabs.
However, conversion was associated with economic and political advantages, and Muslim elites were reluctant to see their privileges diluted.
Public policy towards converts varied depending on the region and was changed by successive Umayyad caliphs.
These circumstances provoked opposition from non-Arab converts, whose ranks included many active soldiers, and helped set the stage for the civil war which ended with the fall of the Umayyad dynasty
Conversions and tax reforms
The Arab-Muslim conquests followed a general pattern of nomadic conquests of settled regions, whereby the conquering peoples became the new military elite and reached a compromise with the old elites by allowing them to retain local political, religious, and financial authority.
Peasants, workers, and merchants paid taxes, while members of the old and new elites collected them.
Payment of taxes, which for peasants often reached half of the value of their produce, was not only an economic burden, but also a mark of social inferiority.
Scholars differ in their assessment of relative tax burdens before and after the conquests. John Esposito
states that in effect this meant lower taxes.
According to Bernard Lewis
, available evidence suggests that the change from Byzantine to Arab rule was "welcomed by many among the subject peoples, who found the new yoke far lighter than the old, both in taxation and in other matters".
In contrast, Norman Stillman
writes that although the tax burden of the Jews under early Islamic rule was comparable to that under previous rulers, Christians of the Byzantine Empire (though not Christians of the Persian empire, whose status was similar to that of the Jews) and Zoroastrians of Iran shouldered a considerably heavier burden in the immediate aftermath of the conquests.

containing a bilingual Greek-Arabic tax receipt dated from 643 AD
In the wake of the early conquests taxes could be levied on individuals, on the land, or as collective tribute.
During the first century of Islamic expansion, the words jizya
were used in all three senses, with context distinguishing between individual and land taxes.
Regional variations in taxation at first reflected the diversity of previous systems.
The Sasanian Empire
had a general tax on land and a poll tax having several rates based on wealth, with an exemption for aristocracy.
This poll tax was adapted by Arab rulers, so that the aristocracy exemption was assumed by the new Arab-Muslim elite and shared by local aristocracy who converted to Islam.
The nature of Byzantine taxation remains partly unclear, but it appears to have been levied as a collective tribute on population centers and this practice was generally followed under the Arab rule in former Byzantine provinces.
Collection of taxes was delegated to autonomous local communities on the condition that the burden be divided among its members in the most equitable manner.
In most of Iran and Central Asia local rulers paid a fixed tribute and maintained their autonomy in tax collection.
Difficulties in tax collection soon appeared.
Egyptian Copts, who had been skilled in tax evasion since Roman times, were able to avoid paying the taxes by entering monasteries, which were initially exempt from taxation, or simply by leaving the district where they were registered.
This prompted imposition of taxes on monks and introduction of movement controls.
In Iraq, many peasants who had fallen behind with their tax payments converted to Islam and abandoned their land for Arab garrison towns in hope of escaping taxation.
Faced with a decline in agriculture and a treasury shortfall, the governor of Iraq, al-Hajjaj
, forced peasant converts to return to their lands and subjected them to the taxes again, effectively forbidding them from converting to Islam.
In Khorasan, a similar phenomenon forced the native aristocracy to compensate for the shortfall in tax collection out of their own pockets, and they responded by persecuting peasant converts and imposing heavier taxes on poor Muslims.
The situation where conversion to Islam was penalized in an Islamic state could not last, and the devout Umayyad caliph Umar II
(717–720) has been credited with changing the taxation system.
Modern historians doubt this account, although details of the transition to the system of taxation elaborated by Abbasid-era jurists are still unclear.
Umar II ordered governors to cease collection of taxes from Muslim converts, but his successors obstructed this policy and some governors sought to stem the tide of conversions by introducing additional requirements such as circumcision and the ability to recite passages from the Quran.
Taxation-related grievances of non-Arab Muslims contributed to the opposition movements which resulted in the Abbasid revolution
Under the new system that was eventually established, kharaj came to be regarded as a tax levied on the land, regardless of the taxpayer's religion.
The poll-tax was no longer levied on Muslims, but the treasury did not necessarily suffer and converts did not gain as a result, since they had to pay zakat
, which was probably instituted as a compulsory tax on Muslims around 730.
The terminology became specialized during the Abbasid era, so that kharaj
no longer meant anything more than land tax, while the term jizya
was restricted to the poll-tax on dhimmis
The influence of jizya on conversion has been a subject of scholarly debate.
Julius Wellhausen held that the poll tax amounted to so little that exemption from it did not constitute sufficient economic motive for conversion.
Similarly, Thomas Arnold
states that jizya was "too moderate" to constitute a burden, "seeing that it released them from the compulsory military service that was incumbent on their Muslim fellow subjects." He further adds that converts escaping taxation would have to pay the legal alms, zakat, that is annually levied on most kinds of movable and immovable property.
Other early 20th century scholars suggested that non-Muslims converted to Islam en masse
in order to escape the poll tax, but this theory has been challenged by more recent research.
Daniel Dennett has shown that other factors, such as desire to retain social status, had greater influence on this choice in the early Islamic period.
Policy toward non-Muslims
The Arab conquerors did not repeat the mistakes which had been made by the governments of the Byzantine and Sasanian empires, which had tried and failed to impose an official religion on subject populations, which had caused resentments that made the Muslim conquests more acceptable to them.
Instead, the rulers of the new empire generally respected the traditional middle-Eastern pattern of religious pluralism, which was not one of equality but rather of dominance by one group over the others.
After the end of military operations, which involved sacking of some monasteries and confiscation of Zoroastrian fire temples
in Syria and Iraq, the early caliphate was characterized by religious tolerance and peoples of all ethnicities and religions blended in public life.
Before Muslims were ready to build mosques in Syria, they accepted Christian churches as holy places and shared them with local Christians.
In Iraq and Egypt, Muslim authorities cooperated with Christian religious leaders.
Numerous churches were repaired and new ones built during the Umayyad era.
The first Umayyad caliph Muawiyah
sought to reassure the conquered peoples that he was not hostile to their religions and made an effort to enlist support from Christian Arab elites.
There is no evidence for public display of Islam by the state before the reign of Abd al-Malik
(685–705), when Quranic verses and references to Muhammad suddenly became prominent on coins and official documents.
This change was motivated by a desire to unify the Muslim community after the second civil war
and rally them against their chief common enemy, the Byzantine empire.
A further change of policy occurred during the reign of Umar II (717–720).
The disastrous failure of the siege of Constantinople in 718 which was accompanied by massive Arab casualties led to a spike of popular animosity among Muslims toward Byzantium and Christians in general.
At the same time, many Arab soldiers left the army for civilian occupations and they wished to emphasize their high social status among the conquered peoples.
These events prompted introduction of restrictions on non-Muslims
, which, according to Hoyland, were modeled both on Byzantine curbs on Jews, starting with the Theodosian Code
and later codes, which contained prohibitions against building new synagogues and giving testimony against Christians, and on Sassanid regulations that prescribed distinctive attire for different social classes.
In the following decades Islamic jurists elaborated a legal framework in which other religions would have a protected but subordinate status.
Islamic law followed the Byzantine precedent of classifying subjects of the state according to their religion, in contrast to the Sasanian model which put more weight on social than on religious distinctions.
In theory, like the Byzantine empire, the caliphate placed severe restrictions on paganism, but in practice most non-Abrahamic communities of the former Sasanian territories were classified as possessors of a scripture (ahl al-kitab
) and granted protected (dhimmi
In Islam, Christians and Jews are seen as "Peoples of the Book" as the Muslims accept both Jesus Christ and the Jewish prophets as their own prophets, which accorded them a respect that was not reserved to the "heathen" peoples of Iran, Central Asia and India.
In places like the Levant and Egypt, both Christians and Jews were allowed to maintain their churches and synagogues and keep their own religious organizations in exchange for paying the jizya
At times, the caliphs engaged in triumphalist gestures, like building the famous Dome of the Rock mosque in Jerusalem from 690-692 on the site of the Jewish Second Temple, which had been destroyed by the Romans in 70 AD--though the use of Roman and Sassanian symbols of power in the mosque suggests its purpose was partly to celebrate the Arab victories over the two empires.
Those Christians out of favor with the prevailing orthodoxy in the Roman empire often preferred to live under Muslim rule as it meant the end of persecution.
As both the Jewish and Christian communities of the Levant and North Africa were better educated than their conquerors, they were often employed as civil servants in the early years of the caliphate.
However, a reported saying of Muhammad that "Two religions may not dwell together in Arabia" led to different policies being pursued in Arabia with conversion to Islam being imposed rather than merely encouraged.
With the notable exception of Yemen, where a large Jewish community existed right up until the middle of the 20th century, all of the Christian and Jewish communities in Arabia "completely disappeared".
The Jewish community of Yemen seems to have survived as Yemen was not regarded as part of Arabia proper in the same way that the Hejaz and the Nejd were.
Mark R. Cohen
writes that the jizya paid by Jews under Islamic rule provided a "surer guarantee of protection from non-Jewish hostility" than that possessed by Jews in the Latin West, where Jews "paid numerous and often unreasonably high and arbitrary taxes" in return for official protection, and where treatment of Jews was governed by charters which new rulers could alter at will upon accession or refuse to renew altogether.
The Pact of Umar
, which stipulated that Muslims must "do battle to guard" the dhimmis and "put no burden on them greater than they can bear", was not always upheld, but it remained "a steadfast cornerstone of Islamic policy" into early modern times.

Quote: "Some studies question the nearly synonymous use of the terms kharaj and jizya in the historical sources. The general view suggests that while the terms kharaj and jizya seem to have been used interchangeably in early historical sources, what they referred to in any given case depended on the linguistic context. If one finds references to "a kharaj on their heads," the reference was to a poll tax, despite the use of the term kharaj, which later became the term of art for land tax. Likewise, if one fins the phrase "jizya on their land," this referred to a land tax, despite the use of jizya which later come to refer to the poll tax. Early history therefore shows that although each term did not have a determinate technical meaning at first, the concepts of poll tax and land tax existed early in Islamic history."

The (cor)relation between the payment of the poll-tax and conversion to Islam, has long been the subject of scholarly debate. At the beginning of the twentieth century scholars suggested that after the Muslim conquest the local populations converted en masse to evade the payment of the poll tax. This assumption has been challenged by subsequent research. Indeed Dennett's study clearly showed that the payment of the poll tax was not a sufficient reason to convert after the Muslim conquest and that other factors—such as the wish to retain social status—had greater influence. According to Inalcik the wish to evade payment of the jizya was an important incentive for conversion to Islam in the Balkans, but Anton Minkov has recently argued that taxation was only one of a number of motivations.

Conversion to Islam was certainly attended by a certain pecuniary advantage, but his former religion could have had but little hold on a convert who abandoned it merely to gain exemption from the jizyah; and now, instead of jizyah, the convert had to pay the legal alms, zakāt, annually levied on most kinds of movable and immovable property.
