This post is based on the podcast episode with Hannah-Lena Hagemann about her book The Kharijites in Early Islamic Historical Tradition. The post was generated by AI but edited by a human.
In 657 CE, two armies confronted one another near the Euphrates River in what is now Syria.
One was led by Ali ibn Abi Talib, the fourth caliph and a close relative of the Prophet Muhammad.
The other represented Muawiyah ibn Abi Sufyan, the powerful governor of Syria who challenged Ali's authority.
The confrontation became known as the Battle of Siffin.
According to the traditional accounts, the battle ended not with a decisive military victory but with an agreement to submit the dispute to arbitration.
That decision had enormous consequences.
A faction associated with Ali's forces rejected the arbitration and broke away from his camp. These dissidents became known as the Kharijites, a group that would be remembered in Islamic historical tradition as rebellious, uncompromising, and dangerously extreme.
But how much of this story can historians actually establish?
And why did the Kharijites become such enduring villains in Islamic memory?
These are the questions I explored with historian Hannah-Lena Hagemann of the University of Hamburg, author of The Kharijites and Early Islamic Historical Tradition.
Hagemann approaches the subject from a different perspective than many earlier historians.
Rather than beginning with the assumption that the surviving accounts accurately describe the historical Kharijites, she examines the literary patterns through which later Muslim historians represented them.
Her central argument is that the Kharijites became more than a historical movement.
They became a literary device through which authors explored the dangers of rebellion, the boundaries of legitimate religious behavior, and the importance of maintaining the unity of the Muslim community.
The First Fitna: Islam's First Civil War
To understand the origins of the Kharijites, we need to return to the decades following Muhammad's death in 632 CE.
According to the traditional Sunni account, Muhammad was succeeded by four caliphs later remembered as the Rashidun, or Rightly Guided Caliphs.
The first was Abu Bakr, who ruled for approximately two years.
He was succeeded by Umar ibn al-Khattab, whose reign lasted about a decade and witnessed major territorial expansion.
The third caliph, Uthman ibn Affan, became the focus of increasing political opposition.
Islamic historical traditions accuse Uthman of favoring relatives and associates, mismanaging public resources, and departing from the precedents established by Muhammad.
The historical reliability of individual accusations remains disputed.
What is clear in the traditional chronology is that Uthman was assassinated in 656 CE.
His death precipitated the First Fitna, the first major civil war within the Muslim community.
Ali ibn Abi Talib succeeded him, but his authority was contested from the beginning.
Muawiyah, a relative of Uthman who had governed Syria for many years, became one of his most formidable opponents.
The resulting conflict was not simply a disagreement between two individuals.
It involved competing political networks, regional loyalties, and rival claims to legitimate leadership.
Why Was Muawiyah So Powerful in Syria?
During our conversation, I asked Hagemann whether Muawiyah's Syrian supporters had come from Arabia during the early Islamic conquests or whether they represented older local communities.
Her answer was that his political base combined both.
Muawiyah himself came from the Hejaz in western Arabia.
But by the time Uthman was assassinated, he had spent approximately twenty years governing Syria.
During that period, he developed relationships with Arab military settlers and with tribes already established in the region.
Among the most important were the Banu Kalb, a tribal confederation with substantial Christian connections.
Muawiyah married a woman from the Kalb, and their son Yazid would eventually succeed him as caliph.
These alliances helped give Muawiyah a powerful regional base.
Hagemann argues that Muawiyah probably possessed a stronger and more cohesive network of supporters than Ali.
Ali's followers were distributed across different regions, including Medina and Iraq.
Kufa, in particular, became closely associated with his political and military support.
But these supporters did not necessarily agree about how he should respond to Muawiyah.
The resulting divisions became central to the later narratives of Ali's caliphate.
The Battle of Siffin and the Origins of the Kharijites
In 657 CE, Ali's forces confronted Muawiyah's army at Siffin, near the Euphrates.
The traditional accounts describe a battle that appeared to be moving in Ali's favor before Muawiyah's side proposed arbitration.
Instead of allowing the fighting to determine the outcome, representatives from the two camps would attempt to resolve the dispute.
A group associated with Ali's supporters rejected this arrangement.
These dissidents became the Kharijites.
But Hagemann emphasizes that the sources preserve conflicting explanations for what actually happened.
One version portrays the dissidents as rejecting arbitration from the beginning.
They believed that God would determine the righteous side through victory in battle.
In this account, accepting arbitration meant allowing human judgment to interfere with a conflict that should have been settled through divine favor.
Another version tells a different story.
It suggests that the future Kharijites initially pressured Ali to accept arbitration.
Only afterward did they object to the terms of the agreement.
According to this version, the problem was that the arbitrators could exercise their own judgment rather than relying exclusively on the Quran.
A third narrative places their opposition after the arbitration decision itself became known.
These accounts are not easily reconciled.
When I asked Hagemann which version she considered most plausible, she declined to select one.
Her reason was methodological.
The surviving narratives contain multiple layers of interpretation, political argument, and literary development.
Without independent evidence against which to test them, historians cannot confidently identify which account preserves the original sequence of events.
That uncertainty is central to her approach.
What Happened After the Battle of Siffin?
The traditional narratives describe further confrontations between Ali and the Kharijites.
The most famous was the Battle of Nahrawan in 658 CE.
Ali's forces defeated the Kharijites, killing many of their fighters.
Nevertheless, the movement survived.
In 661 CE, Ali was assassinated in Kufa by a man traditionally identified as a Kharijite.
His death marked the end of the Rashidun period in the conventional Sunni chronology.
Muawiyah subsequently established the Umayyad dynasty.
The Kharijites, however, did not disappear.
Over the following generations, groups described as Kharijites appeared in different regions of the expanding Islamic world.
Some opposed the Umayyads.
Others were involved in conflicts during the early Abbasid period.
The sources describe multiple Kharijite movements with different leaders and theological positions.
By the later ninth century, the historical accounts increasingly present some Kharijites as religious intellectuals rather than exclusively as militant rebels.
This diversity creates a major problem for historians.
Were these groups part of one coherent movement?
Or did later authors apply the label “Kharijite” to different forms of religious and political opposition?
Hagemann argues that the surviving texts often make very different people appear much more alike than they probably were.
The Problem with Our Sources on Early Islamic History
One of the most important issues in the interview was the chronological distance between the events and the surviving historical accounts.
The Battle of Siffin occurred in 657 CE.
But the earliest substantial Arabic chronicles that survive in recognizable form date from approximately the middle of the ninth century.
That leaves a gap of roughly two centuries.
Earlier material certainly existed.
Reports circulated orally, and scholars recorded traditions in notes and other written forms.
Hadith collections also preserve material about the early Muslim community.
But the surviving accounts underwent processes of selection, transmission, editing, and literary elaboration.
Hagemann points out that a report attributed to an early eyewitness may display the literary conventions of much later writers.
This does not automatically mean the entire report was invented.
It does mean that its present form cannot simply be assumed to reproduce what an eyewitness originally said.
For Hagemann, the first task is therefore to understand the narratives themselves.
What recurring motifs appear?
How are characters constructed?
What moral judgments do the accounts encourage?
And what political or theological concerns might have shaped their transmission?
Only after asking these questions can historians begin reassessing the historical movement behind the stories.
Were the Kharijites Really Religious Extremists?
The Kharijites are frequently portrayed as extraordinarily pious.
They pray constantly.
They fast extensively.
Some are described as having visible marks on their foreheads from repeated prostration.
They are depicted as intensely committed to divine law.
But the same narratives also portray them as capable of extreme violence.
Hagemann describes this combination as militant piety.
The Kharijites appear as people whose religious devotion has become dangerously excessive.
They follow divine commandments so rigidly that their piety becomes a source of bloodshed.
At first glance, this seems to distinguish them from the rest of the early Muslim community.
But Hagemann identifies a significant problem.
Many of the same characteristics appear in positive descriptions of early Muslim warriors.
The companions of Muhammad are also depicted as intensely devout.
Frontier fighters are praised for combining military courage with religious dedication.
Warriors who sacrifice their lives for God can be celebrated as exemplary believers.
The qualities themselves are therefore not uniquely Kharijite.
What changes is the way those qualities are evaluated.
The same combination of devotion and militancy can become admirable or reprehensible depending on whom it is directed against.
Why Did Kharijite Violence Become Illegitimate?
This distinction is particularly clear in the discussion of jihad.
Hagemann observes that the historical narratives rarely describe Kharijite warfare as jihad.
The term sometimes appears in speeches attributed to Kharijite leaders.
But the narrators themselves generally avoid applying it to their campaigns.
Why?
Because jihad carries a positive association with legitimate religious struggle.
The Kharijites, however, are usually presented as fighting the wrong enemies.
Instead of directing their violence against external opponents, they fight other Muslims.
They challenge rulers.
They attack members of their own community.
Their warfare threatens the cohesion of the Islamic polity.
Hagemann argues that this distinction was especially important to later historians writing during periods of political fragmentation.
The Kharijites could serve as a warning about what happens when religious zeal overrides communal unity.
Their behavior illustrated the dangers of directing the energies of religious warfare inward.
In this interpretation, the problem was not simply that the Kharijites were militant.
It was that their militancy threatened the community from within.
What Does the Name Kharijite Mean?
The name Kharijite is usually connected to the Arabic root kharaja, meaning “to go out” or “to depart.”
The term can therefore be understood as referring to those who separated from the community.
That interpretation fits the traditional story of their departure from Ali's camp.
But Hagemann discusses another name associated with them: Shurat, often translated as “the sellers.”
This name evokes the religious idea of selling one's life or possessions in exchange for divine reward in the hereafter.
The concept is rooted in Quranic language and appears in broader early Islamic traditions of sacrifice.
Hagemann suggests that Shurat may have been closer to a name some Kharijites used for themselves.
Poetry attributed to Kharijite figures employs the term.
But there is an important qualification.
Because the authenticity and transmission of this poetry are difficult to establish, we cannot be certain that it preserves the movement's own terminology.
Even so, the contrast between the two names is revealing.
“Kharijite” emphasizes departure and separation.
“Shurat” emphasizes religious sacrifice.
One label can portray the group as dangerous outsiders.
The other can present its members as believers willing to surrender their lives for God.
Why Do Kharijites Sound the Same Across Two Centuries?
Hagemann's book identifies a striking pattern in the historical accounts.
Kharijites living in different periods and regions often behave in remarkably similar ways.
They express similar beliefs.
They make similar accusations.
They deliver similar speeches.
They display the same combination of piety and violence.
Yet the people associated with Kharijism were enormously diverse.
The sources include early companions of Muhammad, former Umayyad soldiers, local elites, religious activists, and even bandits.
Their political circumstances differed considerably.
Their regional backgrounds varied.
Their objectives were not necessarily identical.
Why, then, do the narratives portray them so consistently?
Hagemann argues that later historians were using recognizable literary patterns.
The Kharijite became a stock character through whom certain moral and political questions could be explored.
The stories were not necessarily designed to document the distinctive beliefs of each historical group.
Instead, they often presented a recurring model of excessive religious commitment and destructive rebellion.
This is especially difficult to challenge because independent Kharijite historical writings have not survived in comparable abundance.
We possess poetry and speeches attributed to Kharijites.
But we do not have a substantial body of independent Kharijite chronicles through which to compare their own accounts with those of their opponents.
The surviving picture is therefore deeply asymmetrical.
The Kharijites as a Defense of Ali
One of Hagemann's most original arguments concerns the literary role of the Kharijites in accounts of Ali.
Ali became an enormously important figure in Islamic religious memory.
For Shia Muslims, his authority acquired foundational theological significance.
In Sunni traditions, he became one of the four Rightly Guided Caliphs.
He also served as an important precedent in discussions of how legitimate rulers should respond to rebellion.
But the narratives of his caliphate contain difficult questions.
Why did he agree to arbitration at Siffin?
Did that decision undermine his claim to leadership?
Did he make a disastrous political mistake?
Was he justified in fighting the Kharijites at Nahrawan?
Hagemann argues that the Kharijites frequently function as the characters who voice these criticisms.
They confront Ali.
They accuse him of compromising his position.
They question his judgment.
And Ali, or his representatives, responds.
In this way, the narrative can acknowledge criticisms of Ali while also providing answers to them.
The Kharijites become a literary mechanism for defending his conduct.
Rather than simply recording a dispute, the accounts create a framework through which later readers can evaluate and ultimately reconcile Ali's controversial decisions with his revered status.
Did Later Historians Exaggerate Ali's Importance?
Our conversation also addressed how different communities remembered the First Fitna.
Hagemann notes that many surviving Arabic historical traditions reflect Iraqi perspectives.
That matters because Iraq, especially Kufa, was closely associated with Ali.
Syrian and Syriac sources sometimes present the period differently.
Rather than giving Ali's caliphate the same central position, some accounts move relatively quickly from Uthman's assassination through a period of civil war to Muawiyah's accession.
This does not mean that Ali was unknown in Syria.
It means that his political significance was not necessarily remembered or narrated in the same way everywhere.
Hagemann suggests that the importance of particular events accumulated over time.
The arbitration at Siffin became increasingly significant as later communities developed competing interpretations of legitimate leadership.
The killing of Husayn ibn Ali at Karbala in 680 CE similarly acquired profound significance in later Shia memory.
These events were real components of early Islamic history, but their place within religious and political memory developed over subsequent generations.
Historians must therefore distinguish between an event's immediate political significance and the significance later communities assigned to it.
Why Are the Kharijites Sometimes Portrayed as Heroes?
Although the Kharijites are usually presented negatively, Hagemann identifies important exceptions.
Sometimes they appear courageous, principled, and even admirable.
The difference often depends on their opponents.
For example, the Umayyad governor al-Hajjaj ibn Yusuf has an extremely negative reputation in many Islamic historical narratives.
He is frequently portrayed as harsh, violent, and tyrannical.
When Kharijites confront a figure like al-Hajjaj, their own religious commitment can appear more sympathetic.
They may become brave rebels standing against an unjust ruler.
Hagemann also discusses a narrative in which Kharijites refrain from rebellion during Ali's rule but take up arms once Muawiyah becomes caliph.
The story presents their judgment of the two rulers as fundamentally different.
These variations reveal that the portrayal of Kharijites was not fixed.
Their character traits could be used to praise or condemn them.
A Kharijite confronting a respected companion might appear as a dangerous fanatic.
A Kharijite confronting a notoriously unjust governor might appear as a principled martyr.
The literary function depends on the moral relationship between the characters.
The Kharijites as a Military Lesson
One of the most surprising sections of our conversation concerned military leadership.
Hagemann found that in certain historical narratives, especially those preserved by al-Tabari, Kharijite opponents function almost like tests of a commander's competence.
The Kharijites are portrayed as fierce and dangerous warriors.
Their opponents succeed or fail depending on whether they follow sound military practices.
Good commanders establish defensive positions.
They dig trenches around their camps.
They organize night watches.
They deploy advance guards.
They consult advisers before battle.
Bad commanders neglect these precautions.
And when their armies are overwhelmed by Kharijite fighters, the narrative shows why.
The stories become lessons in military leadership.
The Kharijites themselves remain relatively static.
Their role is to expose the competence or incompetence of the commanders who confront them.
This is another example of how the historical narratives may tell us as much about their authors' interests as about the groups they describe.
Why the Kharijites Still Matter
Hagemann observes that the name Kharijite continues to be used as an accusation.
Modern Muslim commentators sometimes apply it to contemporary militant movements or political opponents.
Groups such as ISIS and Boko Haram have been described by critics as Kharijite or neo-Kharijite.
These comparisons are modern polemical judgments, not evidence of direct historical continuity.
Their significance lies partly in the durability of the label.
A group that emerged in accounts of seventh-century political conflict became an enduring symbol of dangerous religious extremism.
The name continued to carry power long after the historical circumstances that produced it had disappeared.
This is one reason Hagemann finds the subject so important.
The Kharijites offer a window into how religious communities construct memories of rebellion.
They reveal how political opponents become moral archetypes.
And they show how historical writing can transform complicated events into lessons about authority and belonging.
Conclusion: Reconsidering Islam's First Rebels
The Kharijites occupy a distinctive place in early Islamic history.
They are associated with the Battle of Siffin, the rejection of arbitration, the Battle of Nahrawan, and the assassination of Ali.
Later narratives portray them as intensely pious, militant, and unwilling to compromise.
But Hannah-Lena Hagemann's work challenges us to examine those descriptions more carefully.
The surviving accounts were written and transmitted by people with their own political, theological, and literary concerns.
They often reduce diverse historical movements to recurring character types.
They use the Kharijites to defend Ali, criticize unjust rulers, warn against civil war, and teach lessons about military leadership.
That does not mean the Kharijites were fictional.
It means that the historical groups behind the narratives are more difficult to recover than traditional summaries suggest.
To understand them, we must first understand how they were remembered.
And that is precisely what makes the study of the Kharijites so revealing.
Their history is not only a history of rebellion.
It is also a history of how societies decide who belongs, who threatens the community, and whose actions can be considered righteous.
The Kharijites: Frequently Asked Questions
1. Who were the Kharijites?
The Kharijites were groups associated with early Islamic political and religious opposition. Traditional accounts trace their emergence to a faction that separated from Ali during the conflict with Muawiyah in the seventh century CE.
2. What does Kharijite mean?
The name is commonly connected to the Arabic root kharaja, meaning “to go out” or “to depart.” It is often interpreted as referring to those who separated from Ali's camp or the wider Muslim community.
3. When did the Kharijites emerge?
The traditional account places their emergence during the First Fitna, particularly around the Battle of Siffin in 657 CE and the subsequent arbitration controversy.
4. What was the First Fitna?
The First Fitna was the first major civil war within the early Muslim community, conventionally dated to 656–661 CE. It followed the assassination of Caliph Uthman and involved disputes over political authority.
5. What happened at the Battle of Siffin?
Ali and Muawiyah confronted one another near the Euphrates in 657 CE. The surviving narratives describe an agreement to arbitrate their dispute, but differ considerably over the details and the reasons some of Ali's supporters rejected it.
6. Why did the Kharijites oppose Ali?
The traditional accounts offer several explanations, including opposition to arbitration, objections to its terms, and dissatisfaction with the resulting judgment. Hannah-Lena Hagemann emphasizes that the contradictory narratives make the original sequence difficult to establish.
7. Who was Muawiyah?
Muawiyah ibn Abi Sufyan was the governor of Syria who challenged Ali's authority and later became the founder of the Umayyad dynasty.
8. What was the Battle of Nahrawan?
The Battle of Nahrawan, traditionally dated to 658 CE, was a confrontation in which Ali's forces defeated a group of Kharijite opponents.
9. Did the Kharijites assassinate Ali?
Ali was assassinated in Kufa in 661 CE by Ibn Muljam, who is traditionally identified as a Kharijite. The precise historical context is reconstructed primarily from later sources.
10. Were the Kharijites Sunni or Shia?
The Kharijites emerged before Sunni and Shia identities developed into their later forms. They are conventionally treated as a distinct current within early Islamic history.
11. What did the Kharijites believe?
Different groups associated with Kharijism held different positions. Later sources frequently emphasize their uncompromising piety, opposition to certain rulers, and willingness to challenge authority, but these descriptions may reflect literary stereotypes.
12. What does Shurat mean?
Shurat means “the sellers” and refers to people willing to give up their lives for divine reward. Hagemann discusses the possibility that some Kharijites used this term for themselves.
13. Why were the Kharijites considered heretics?
Later Islamic traditions frequently portrayed them as religious extremists whose uncompromising interpretations justified violence against fellow Muslims and threatened communal unity.
14. Were all Kharijites violent?
The historical sources associate different groups with different forms of activity, including military rebellion and intellectual or quietist traditions. It would be misleading to treat all groups labeled Kharijite as identical.
15. Why are Kharijites sometimes portrayed positively?
Hagemann argues that their portrayal often depends on their opponents. When they confront rulers depicted as tyrannical, Kharijites may appear courageous and principled rather than fanatical.
16. How reliable are the sources about the Kharijites?
Many surviving historical accounts were compiled approximately two centuries or more after the earliest events. They draw on older material but also reflect literary conventions and later political concerns.
17. Who was al-Tabari?
Al-Tabari was an influential Muslim historian who died in 923 CE. His historical compilation preserves extensive accounts of early Islamic political conflicts, including narratives involving Kharijite groups.
18. What is the relationship between the Kharijites and the Ibadis?
Ibadism is historically associated with debates about early Kharijism, but its relationship to the Kharijite label is complex and contested. Modern Ibadis should not simply be equated with the militant stereotypes found in hostile historical narratives.
19. Can archaeology help historians study the Kharijites?
Material evidence, especially coins bearing names associated with Kharijite figures, can help investigate regional activity and political authority. Hagemann also emphasizes tribal data and other methods beyond literary sources.
20. Why are the Kharijites important today?
The Kharijite label continues to appear in modern religious and political polemics. Studying its historical development helps explain how accusations of extremism and illegitimate rebellion become enduring features of religious memory.
