TheAbbasid revolution (Arabic:اَلثَّوْرَة اَلْعَبَّاسِيَّةِ,romanized: aṯ-Ṯawra al-ʿAbbāsiyyah),[a][1] was the overthrow of theUmayyad Caliphate (661–750), the second of the four majorcaliphates inIslamic history, by the third, theAbbasid Caliphate (750–1517).
The Abbasid revolt originated in the eastern province ofKhorasan in the mid-8th century, fueled by widespread discontent with Umayyad rule. The Abbasids, claiming descent fromMuhammad's uncle Abbas, capitalized on various grievances, including discrimination against non-Arab Muslims (mawali), heavy taxation, and perceived impiety of Umayyad rulers.[2] Led byAbu Muslim Khorasani, Abu Muslim's army composed largely of Arab settlers disillusioned with Umayyad rule, marched under black banners, forming a powerful force that swept westward in open revolt,[3] defeating Umayyad forces. The decisiveBattle of the Zab in 750 saw the Abbasid army triumph over the last Umayyad caliph,Marwan II. This victory led to the fall of the Umayyad dynasty and the establishment of Abbasid rule, marking a significant shift in the caliphate's power base from Syria to Iraq and ushering in a new era of Islamic governance.[4]
By the 740s, the Umayyad Empire found itself in critical condition. Asuccession crisis in 744 led to theThird Fitna, which raged across the Middle East for three years. The very next year,al-Dahhak ibn Qays al-Shaybani initiated aKharijite rebellion that would continue until 746. Concurrent with this, a rebellion broke out in reaction toMarwan II's decision to move the capital fromDamascus toHarran, resulting in the destruction ofHoms – also in 746. It was not until 747 that Marwan II was able to pacify the provinces; the Abbasid revolution began within months.[5]
Nasr ibn Sayyar was appointed governor ofKhorasan byHisham ibn Abd al-Malik in 738. He held on to his post throughout the war of succession, being confirmed as governor by Marwan II in the aftermath.[5]
Khorasan's expansive size and low population density meant that the Arab denizens – both military and civilian – lived largely outside of the garrisons built during the spread of Islam into Persia. This was in contrast to the rest of the Umayyad provinces, where Arabs tended to seclude themselves in fortresses to avoid interacting with the locals.[6] Arab settlers in Khorasan left their traditional lifestyle and settled among the nativeIranian peoples.[5] While intermarriage with non-Arabs elsewhere in the Empire was discouraged or even banned,[7][8] it slowly became a habit within eastern Khorasan; and the Arabs began adoptingPersian dress and as the two languages influenced one another, the ethnic barriers gradually eroded.[9]
Support for the Abbasid revolution came from people of diverse backgrounds, with almost all levels of society supporting armed opposition to Umayyad rule.[10] This was especially pronounced among Muslims of non-Arab descent,[11][12][13] though even Arab Muslims resented Umayyad rule and centralized authority over their nomadic lifestyles.[12][14] BothSunnis andShias supported efforts to overthrow the Umayyads,[10][11][13][15][16] as did non-Muslim subjects of the empire who resented religious discrimination.[17]
Following theBattle of Karbala, which led to the massacre ofHusayn ibn Ali, the grandson of the prophetMuhammad, alongside his kin and companions by the Umayyad army in 680 CE, the event became a rallying cry of opposition against the Umayyads. The Abbasids also used the memory of Karbala extensively to gain popular support against the Umayyads, which further rallied Shi'ite support.[19] In the decades preceding the Abbasid revolution, several Shi'ite andAlid uprisings had taken place against the Umayyads. To an extent, rebellion against the Umayyads bore an early association with Shi'ite ideas.[14][20] This included theTawwabin uprising led bySulayman ibn Surad in 684–685 andMukhtar al-Thaqafi's uprising in 685–687, following the murder of Husayn ibn Ali in 680. Later on, theRevolts of Zayd ibn Ali in 740 and the uprising ofAbd Allah ibn Mu'awiya in 747–748, who even established temporary rule overIran,[16] paved way for the Abbasid revolution.[21][22]
The Hashimiyya movement (a sub-sect of the Shi'iteKaysanites) was largely responsible for starting the final efforts against the Umayyad dynasty,[5] initially with the goal of replacing the Umayyads with anAlid ruling family.[23][24] Initially, the Abbasid family kept quiet about their identity, simply stating that they wanted a ruler from the descendant of Muhammad upon whose choice as caliph the Muslim community would agree to.[25][26] Many Shi'ites naturally assumed that this meant an Alid ruler, a belief which the Abbasids tacitly encouraged to gain Shi'ite support.[27] The Abbasids claimed thatAbu Hashim, the grandson ofAli through his sonMuhammad ibn al-Hanafiyyah, had formally transferred theImamate toMuhammad ibn Ali ibn Abdallah in 717, and thus Imamah was transferred to the house ofal-Abbas.[21][28][22]
Although the anecdote is considered a fabrication,[29] at the time it allowed the Abbasids to rally the supporters of the failed revolt ofMukhtar al-Thaqafi, who had represented themselves as the supporters of Muhammad ibn al-Hanafiyya. By the time the revolution was in full swing, most Kaysanite Shia had either transferred their allegiance to the Abbasid dynasty (in the case of the Hashimiyya),[30][31] or differed to other branches of Shi'ism, and so the Kaysanites ceased to exist.[32]
The Umayyad state is remembered as an Arab-centric state, being run by and for the benefit of those who were ethnically Arab though Muslim in creed.[12][33] The non-Arab Muslims resented their marginal social position and were easily drawn into Abbasid opposition to Umayyad rule.[14][15][28] Arabs dominated the bureaucracy and military, and were housed in fortresses separate from the local population outside of Arabia.[6] Even after converting to Islam, non-Arabs orMawali could not live in these garrison cities. The non-Arabs were not allowed to work for the government nor could they hold officer positions in the Umayyad military and they still had to pay thejizya tax for non-Muslims.[33][34][35][36] Non-Muslims under Umayyad rule were subject to these same injunctions.[37] Racial intermarriage between Arabs and non-Arabs was rare.[7] When it did occur, it was only allowed between an Arab man and a non-Arab woman while non-Arab men were generally not free to marry Arab women.[8]
Conversion to Islam occurred gradually. If a non-Arab wished to convert to Islam, they not only had to give up their own names but also had to remain a second-class citizen.[13][35] The non-Arab would be "adopted" by an Arab tribe,[36] though they would not actually adopt the tribe's name as that would risk pollution of perceived Arab racial purity. Rather, the non-Arab would take the last name of "freedman of al-(tribe's name)", even if they were not a slave prior to conversion. This essentially meant they were subservient to the tribe who sponsored their conversion.[13][38]
Although converts to Islam made up roughly 10% of the native population – most of the people living under Umayyad rule were not Muslim – this percent was significant due to the very small number of Arabs.[12] Gradually, the non-Arab Muslims outnumbered the Arab Muslims, causing alarm among the Arab nobility.[33] Socially, this posed a problem as the Umayyads viewed Islam as the property of the aristocratic Arab families.[39][40] There was a rather large financial problem posed to the Umayyad system as well. If the new converts to Islam from non-Arab peoples stopped paying the jizya tax stipulated by the Qur'an for non-Muslims, the empire would go bankrupt. This lack of civil and political rights eventually led the non-Arab Muslims to support the Abbasids, despite the latter also being Arab.[41]
Even as the Arab governors adopted the more sophisticated Iranian methods of governmental administration, non-Arabs were still prevented from holding such positions.[7] Non-Arabs were not even allowed to wear Arabian style clothing,[42] so strong were the feelings of Arab racial superiority cultivated by the Umayyads. Much of the discontent this caused led to theShu'ubiyya movement, an assertion of non-Arab racial and cultural equality with Arabs. The movement gained support amongEgyptians,Arameans andBerber people,[43] though this movement was most pronounced amongIranian people.[citation needed]
The earlyMuslim conquest of Persia was coupled with ananti-IranianArabization policy which led to much discontent.[44] Up until the time ofAbd al-Malik ibn Marwan, thedivan was dominated by the mawali and accounts were written using thePahlavi script. The controversial Umayyad governorAl-Hajjaj ibn Yusuf forced all the mawali who had left for cities, in order to avoid paying thekharaj tax, to return to their lands. He was upset at the usage ofPersian as the court language in the eastern Islamic empire, and ordered it to be changed to Arabic.[45][46]
Support for the Abbasid revolution was an early example of people of different faiths aligning with a common cause. This was due in large part to policies of the Umayyads which were regarded as particularly oppressive to anyone following a faith other than Islam. In 741, the Umayyads decreed that non-Muslims could not serve in government posts.[47] The Abbasids were aware of this discontent, and made efforts to balance both its Muslim character as well as its partially non-Muslim constituency.[48]
The non-Muslim aristocracy aroundMerv supported the Abbasids, and thus retained their status as a privileged governing class regardless of religious belief.[14]
Beginning around 719, Hashimiyya missions began to seek adherents inKhurasan. Their campaign was framed as one ofproselytism. They sought support for "a member of the House of the Prophet who shall be pleasing to everyone",[49] without making explicit mention of the Abbasids.[27][50] These missions met with success both among Arabs and non-Arabs, although the latter may have played a particularly important role in the growth of the movement. A number of Shi'ite rebellions – by Kaysanites, Hashimiyya and mainstream Shi'ites – took place in the final years of Umayyad rule, just around the same time that tempers were flaring among the Syrian contingents of the Umayyad army regarding alliances and wrongdoings during theSecond[35][51] andThird Fitna.[52]
At this timeKufa was the center for the opposition to Umayyad rule, particularly Ali's supporters and Shias. In 741–42Abu Muslim made his first contact with Abbasid agents there, and eventually he was introduced to the head of Abbasids, ImamIbrahim, inMecca. Around 746,Abu Muslim assumed leadership of the Hashimiyya in Khurasan.[53] Unlike the Alid revolts which were open and straightforward about their demands, the Abbasids along with the Hashimite allies slowly built up an underground resistance movement to Umayyad rule. Secret networks were used to build a power base of support in the eastern Muslim lands to ensure the revolution's success.[20][51] This buildup not only took place right on the heels of theZaydi Revolt in Iraq, but also concurrently with theBerber Revolt inIberia andMaghreb, theIbadi rebellion inYemen andHijaz,[54] and theThird Fitna in theLevant, with the revolt ofal-Harith ibn Surayj inKhurasan andCentral Asia occurring concurrently with the revolution itself.[12][13] The Abbasids spent their preparation time watching as the Umayyad Empire was besieged from within itself in all four cardinal directions,[55] andSchool of Oriental and African StudiesProfessorEmeritusG. R. Hawting has asserted that even if the Umayyad rulers had been aware of the Abbasids' preparations, it would not have been possible to mobilize against them.[5]
In 746, Ibn Surayj began his revolt atMerv without success at first, even losing his secretaryJahm bin Safwan.[56] After joining forces with other rebel factions, Ibn Surayj drove Umayyad governor Nasr ibn Sayyar and his forces toNishapur; the two factions double-crossed each other shortly thereafter, with Ibn Surayj's faction being crushed. Western Khorasan was controlled byAbdallah ibn Mu'awiya at the time, cutting Ibn Sayyar in the east off fromMarwan II. In the summer of 747, Ibn Sayyarsued for peace, which was accepted by the remaining rebels. The rebel leader was assassinated by a son of Ibn Surayj in a revenge attack while at the same time, another Shi'ite revolt had begun in the villages. The son of the remaining rebels signed the peace accord and Ibn Sayyar returned to his post in Merv in August of 747[56] – just after Abu Muslim initiated a revolt of his own.
On 9 June 747 (Ramadan 25, 129AH), Abu Muslim successfully initiated an open revolt against Umayyad rule,[12][57] which was carried out under the sign of theBlack Standard.[53][58][59] Abu Muslim rose in the name of anImam, still unnamed at the time but spoken of asal-Rida, rallying support from Khorasanians and Shi'ites.[60] Close to 10,000 soldiers were under Abu Muslim's command when the hostilities officially began inMerv.[4] On 14 February 748 he established control of Merv,[56] expellingNasr ibn Sayyar less than a year after the latter had put down Ibn Surayj's revolt, and dispatched an army westwards.[53][58][61]
Newly commissioned Abbasid officerQahtaba ibn Shabib al-Ta'i, along with his sonsAl-Hasan ibn Qahtaba andHumayd ibn Qahtaba, pursued Ibn Sayyar toNishapur and then pushed him further west toQumis, in western Persia.[62] That August, al-Ta'i defeated an Umayyad force of 10,000 atGorgan, South East of Caspian Sea. Ibn Sayyar regrouped with reinforcements from the Caliph atRey near today's Capital "Tehran", only for that city to fall as well as the Caliph's commander; once again, Ibn Sayyar fled west and died on 9 December 748 while trying to reachHamedan in south Western Persia.[62] Al-Ta'i rolled west through Khorasan, defeating a 50,000 strong Umayyad force atIsfahan in Central Persia in March 749.
AtNahavand south western Persia, the Umayyads attempted to make their last stand in Persia. Umayyad forces fleeing Hamedan and the remainder of Ibn Sayyar's men joined with those already garrisoned.[62] Qahtaba defeated an Umayyad relief contingent from Syria while his son al-Hasan laid siege to Nahavand for more than two months. The Umayyad military units from Syria within the garrison cut a deal with the Abbasids, saving their own lives by selling out the Umayyad units from Khorasan who were all put to death.[62] After almost ninety years, Umayyad rule in Khorasan had finally come to an end.
At the same time that al-Ta'i took Nishapur Located in North Eastern Khorasan, Abu Muslim was strengthening the Abbasid grip on the Muslim North East. Abbasid governors were appointed overTransoxiana andBactria (Parts of today's Turkmenistan, Tajikistan, Uzbekistan, Kyrgyzstan and Kazakhstan), while the rebels who had signed a peace accord with Nasr ibn Sayyar were also offered a peace deal by Abu Muslim only to be double crossed and wiped out.[62] With the pacification of any rebel elements in the east and the surrender of Nahavand in the west, the Abbasids were the undisputed rulers of Khorasan.

The Abbasids wasted no time in continuing from Persia into Mesopotamia. In August 749, Umayyad commanderYazid ibn Umar al-Fazari attempted to meet the forces of al-Ta'i before they could reachKufa. Not to be outdone, the Abbasids launched a nighttime raid on al-Fazari's forces before they had a chance to prepare. During the raid, al-Ta'i himself was finally killed in battle. Despite the loss, al-Fazari was routed and fled with his forces toWasit.[63] TheSiege of Wasit took place from that August until July 750. Although a respected military commander had been lost, a large portion of the Umayyad forces were essentially trapped inside Wasit and could be left in their virtual prison while more offensive military actions were made.[64]
Concurrently with the siege in 749, the Abbasids crossed theEuphrates and took Kufa.[35][58] The son ofKhalid al-Qasri – a disgraced Umayyad official who had been tortured to death a few years prior – began a pro-Abbasid riot starting at the city's citadel. On 2 September 749, al-Hasan bin Qahtaba essentially just walked right in to the city and set up shop.[64] Some confusion followed whenAbu Salama, an Abbasid officer, pushed for an Alid leader. Abu Muslim's confidante Abu Jahm reported what was happening, and the Abbasids acted preemptively. On Friday, 28 November 749, before the siege of Wasit had even finished,As-Saffah, the great-grandson of Muhammad's uncle,al-Abbas, was recognized as the new caliph in the mosque at Kufa.[53][65] Abu Salama, who witnessed twelve military commanders from the revolution pledging allegiance, was embarrassed into following suit.[64]
Just as quickly as Qahtaba's forces marched from Khorosan to Kufa, so did the forces ofAbdallah ibn Ali andAbu Awn Abd al-Malik ibn Yazid march onMosul(in today's Northern Iraq).[64] At this point Marwan II mobilized his troops fromHarran (Today's South Central Turkey) and advanced toward Mesopotamia. On 16 January 750 the two forces met on the left bank of a tributary of the Tigris in theBattle of the Zab, and nine days later Marwan II was defeated and his army was completely destroyed.[13][35][64][66] The battle is regarded as what finally sealed the fate of the Umayyads. All Marwan II could do was flee through Syria and into Egypt, with each Umayyad town surrendering to the Abbasids as they swept through in pursuit.[64]
Damascus fell to the Abbasids in April, and in AugustMarwan II and his family were tracked down by a small force led by Abu Awn andSalih ibn Ali (the brother of Abdallah ibn Ali) and killed in Egypt.[13][35][53][59][66] Al-Fazari, the Umayyad commander at Wasit, held out even after the defeat of Marwan II in January. The Abbasids promised him amnesty in July, but immediately after he exited the fortress they executed him instead. After almost exactly three years of rebellion, the Umayyad state came to an end.[12][24]
The victors desecrated the tombs of the Umayyads inSyria, sparing only that ofUmar II, and most of the remaining members of the Umayyad family were tracked down and killed.[10][35] When Abbasids underAbd Allah ibn Ali declared amnesty for members of the Umayyad family, eighty gathered inJaffa to receive pardons and all were massacred.[67][68] It was said that the massacre took place during a gathering banquet, with Abd Allah reportedly continuing to dine throughout the event.[69] ʿAbd Allah ibn Ali presented the mass killings of Umayyads as retaliation forHusayn's death atKarbala.[70]
Militarily, the unit organization of the Abbasids was designed with the goal of ethnic and racial equality among supporters. When Abu Muslim recruited mixed Arab and Turks and Iranian officers along the Silk Road, he registered them based not on their tribal or ethno-national affiliations but on their current places of residence.[57] This greatly diminished tribal and ethnic solidarity and replaced both concepts with a sense of shared interests among individuals.[57]
The Abbasid revolution provides an early medieval example of the effectiveness of propaganda. The Black Standard unfurled at the start of the revolution's open phase carried messianic overtones due to past failed rebellions by members of Muhammad's family, with marked eschatological and millennial slants.[4] The Abbasids – their leaders descended from Muhammad's uncleAbbas ibn Abd al-Muttalib – held vivid historical reenactments of the murder of Muhammad's grandsonHusayn ibn Ali by the army of the second Umayyad rulerYazid I, followed by promises of retribution.[4] Focus was carefully placed on the legacy of Muhammad's family while details of how the Abbasids actually intended to rule were not mentioned.[71] While the Umayyads had primarily spent their energy on wiping out the Alid line of the prophetic family, the Abbasids carefully revised Muslim chronicles to put a heavier emphasis on the relationship between Muhammad and his uncle.[71]
The Abbasids spent more than a year preparing their propaganda drive against the Umayyads. There were a total of seventy propagandists throughout the province of Khorasan, operating under twelve central officials.[72]
The Abbasid revolution was distinguished by a number of tactics which were absent in the other, unsuccessful anti-Umayyad rebellions at the time. Chief among them was secrecy. While the Shi'ite and other rebellions at the time were all led by publicly known leaders making clear and well-defined demands, the Abbasids hid not only their identities but also their preparation and mere existence.[51][73] As-Saffah would go on to become the first Abbasid caliph, but he did not come forward to receive the pledge of allegiance from the people until after the Umayyad caliph and a large number of his princes were already killed.[10]
Abu Muslim al-Khorasani, who was the primary Abbasid military commander, was especially mysterious; even his name, which literally means "father of a Muslim from Khorasan" gave no meaningful information about him personally.[72] Even today, although scholars are sure he was one real, consistent individual, there is broad agreement that all concrete suggestions of his actual identity are doubtful.[53] Abu Muslim himself discouraged inquiries about his origins, emphasizing that his religion and place of residence were all that mattered.[72]
Whoever he was, Abu Muslim built a secret network of pro-Abbasid sentiment based among the mixed Arab and Iranian military officers along theSilk Road garrison cities. Through this networking, Abu Muslim ensured armed support for the Abbasids from a multi-ethnic force years before the revolution even came out in the open.[20] These networks proved essential, as the officers garrisoned along the Silk Road had spent years fighting the ferociousTurkic tribes ofCentral Asia and were experienced and respected tacticians and warriors.[61]
In the immediate aftermath, the Abbasids moved to consolidate their power against former allies now seen as rivals.[10] Five years after the revolution succeeded, Abu Muslim was accused of heresy and treason by the second Abbasid caliphAbu Ja'far al-Mansur. Abu Muslim was executed at the palace in 755 despite his reminding al-Mansur that it was he (Abu Muslim) who got the Abbasids into power,[17][24][61] and his travel companions were bribed into silence. Displeasure over the caliph's brutality as well as admiration for Abu Muslim led to rebellions against the Abbasid Dynasty itself throughout Khorasan andKurdistan.[24][74]
Although Shi'ites were key to the revolution's success, Abbasid attempts to claim orthodoxy in light of Umayyad material excess led to continued persecution of Shi'ites.[11][14] Al-Mansur's son,al-Mahdi (775–785), formally declared thatal-Abbas himself was the Imam, thus abandoning the claim that Imamah was transferred through theAlids. To further underline his credibility, he took the titleal-Mahdi.[21] On the other hand, non-Muslims regained the government posts they had lost under the Umayyads.[11] Jews,Nestorian Christians, Zoroastrians and even Buddhists were re-integrated into a more cosmopolitan empire centered around the new, ethnically and religiously diverse city of Baghdad.[4][36][48]
The Abbasids were essentially puppets of secular rulers starting from 945,[10][15] though their rule overBaghdad and its surroundings continued until 1258 when the Mongols sacked Baghdad, while their lineage as nominal caliphs lasted until 1517, when theOttomans conquered Egypt (the seat of the Abbasid caliphate after 1258) and claimed the caliphate for themselves.[12][15] The period of actual, direct rule by the Abbasids lasted almost exactly two-hundred years.[75]
One grandson ofHisham ibn Abd al-Malik,Abd ar-Rahman I, survived and established a kingdom inAl-Andalus (MoorishIberia) after five years of travel westward.[12][13][35] Over the course of thirty years, he ousted the rulingFihrids and resisted Abbasid incursions to establish theEmirate of Córdoba.[76][77] This is considered an extension of the Umayyad Dynasty, and ruled from Cordoba from 756 until 1031.[11][33]
The Abbasid revolution has been of great interest to both Western and Muslim historians.[58] According toState University of New York professor of sociologySaïd Amir Arjomand, analytical interpretations of the revolution are rare, with most discussions simply lining up behind either the Iranic or Arabic interpretation of events.[78] Frequently, early European historians viewed the conflict solely as a non-Arab uprising against Arabs.Bernard Lewis,professor emeritus of Near Eastern Studies atPrinceton University, points out that while the revolution has often been characterized as a Persian victory and Arab defeat, the caliph was still Arab, the language of administration was still Arabic and Arab nobility was not forced to give up its land holdings; rather, the Arabs were merely forced to share the fruits of the empire equally with other races.[58]
ProfessorHamilton Gibb and Professor Lewis were among the first Orientalists to recognize the active role of the Arabs in the Abbasid Revolution. Gibb did not study the Abbasid Revolution directly, but in other writings he highlighted the importance of the Yemeni Arabs in the uprising. He rejected the idea of a popular Persian movement supporting Abu Muslim al-Khorasani and emphasized the non-ethnic character of the revolution, noting that the cities of Khurasan did not seize the opportunity of the revolution to rise up en masse against the Umayyads. On the contrary, historical sources show the opposite. He also argued that the significance of the Abbasid change lay in integrating the privileged Arabs into the wider Muslim community.[79] Professor Lewis notes the role of the Arabs in Khorasan in the revolution, especially in his article on the Abbasids in theEncyclopedia of Islam, but these notes were brief and cautious.[79]
C. W. Previté-Orton argues that the reasons for the decline of the Umayyads was the rapid expansion of Islam. During the Umayyad period, mass conversions broughtIranians,Berbers,Copts, andAssyrians to Islam. These "clients," as the Arabs referred to them, were often better educated and more civilised than their Arab masters. The new converts, on the basis of equality of all Muslims, transformed the political landscape. Previté-Orton also argues that the feud between the Arabs in Syria and the Arabs in Mesopotamia further weakened the empire.[80]
The revolution led to the enfranchisement of non-Arab people who had converted to Islam, granting them social and spiritual equality with Arabs.[81] With social restrictions removed, Islam changed from an Arab ethnic empire to a universal world religion.[36] This led to a great cultural and scientific exchange known as theIslamic Golden Age, with most achievements taking place under the Abbasids. What was later known as Islamic civilization and culture was defined by the Abbasids, rather than the earlier Rashidun and Umayyad caliphates.[15][36][48] New ideas in all areas of society were accepted regardless of their geographic origin, and the emergence of societal institutions that were Islamic rather than Arab began. Though a class of Muslim clergy was absent for the first century of Islam, it was with the Abbasid revolution and after that theUlama appeared as a force in society, positioning themselves as the arbiters of justice and orthodoxy.[81]
With the eastward movement of the capital from Damascus to Baghdad, the Abbasid Empire eventually took on a distinctly Persian character, as opposed to the Arab character of the Umayyads.[14] Rulers became increasingly autocratic, at times claimingdivine right in defense of their actions.[14]
An accurate and comprehensive history of the revolution has proven difficult to compile for a number of reasons. There are no contemporary accounts known to have survived, and most sources were written more than a century after the revolution.[82][83] Because most historical sources were written under Abbasid rule, the description of the Umayyads must be taken with a grain of salt;[82][84] such sources describe the Umayyads, at best, as merely placeholders between the Rashidun and Abbasid caliphates.[85]
The historiography of the revolution is especially significant due to Abbasid dominance of most early Muslim historical narratives;[83][86] it was during their rule that history was established in the Muslim world as an independent field separate from writing in general.[87] The initial two-hundred year period when the Abbasids actually held de facto power over the Muslim world coincided with the first composition of Muslim history.[75] Historiographical surveys often focus on the solidifying of Muslim thought and rites under the Abbasids, with the conflicts between separated classes of rulers and clerics giving rise to the empire's eventual separation of religion and politics.[88]
