More than thirteen centuries have passed since a small group of men, women, and children found themselves surrounded on a sun-baked plain in what is now Iraq. According to the dominant Shia tradition, seventy-two of Husain ibn Ali's companions and relatives were killed. The surviving women and children of the Prophet's household were taken captive. Their leader was Husain ibn Ali, grandson of the Prophet Muhammad, son of Ali ibn Abi Talib, and the third Imam of Shia Islam. The date was the tenth of Muharram, 61 AH — 10 October 680 CE. The place was Karbala.
The Fracture That Became a Faith
To understand Karbala, one must first understand that the early Muslim community was wrestling with questions of authority, legitimacy, and political leadership that remained unsettled after the death of the Prophet Muhammad in 632 CE. The first decades of Islamic history were marked by extraordinary expansion but also by intense political tensions. Disputes emerged over governance, succession, and the distribution of power within the rapidly growing Muslim empire. By the time Ali ibn Abi Talib became Caliph in 656 CE, those tensions had already become severe. His rule was consumed by civil war, including conflict with Muawiyah ibn Abi Sufyan, the powerful governor of Syria.
Ali was assassinated in 661 CE. Muawiyah subsequently consolidated power and established the Umayyad dynasty. His decision to designate his son Yazid as his successor is widely regarded as the moment when the caliphate began evolving from a consultative institution into a hereditary monarchy. The Islamic thinker Abul A'la Maududi, in Caliphate and Kingship, described Yazid's nomination as a constitutional turning point that fundamentally altered the character of Muslim political authority. When Muawiyah died in 680 CE, power passed to Yazid. Many accepted the succession as a political reality. Others did not. Among the most prominent dissenters was Husain ibn Ali.
The Call from Kufa and the Journey to Karbala
At the same time, the city of Kufa in present-day Iraq had become a centre of opposition to Umayyad rule. Numerous Kufans wrote to Husain, urging him to come and assume leadership. The precise number of letters is impossible to establish, but the invitation itself is well attested in the earliest sources. Husain dispatched his cousin Muslim ibn Aqil to assess the situation before setting out himself. Events moved rapidly. Yazid's governor, Ubaydullah ibn Ziyad, reasserted control over Kufa, support for Husain evaporated, and Muslim ibn Aqil was executed. By the time Husain approached Iraq with a small group of relatives and companions, the political landscape had already changed.
Near Karbala, forces loyal to Yazid intercepted the caravan. The group was surrounded, denied access to the Euphrates, and isolated in the desert. On the tenth of Muharram, known thereafter as Ashura, battle became unavoidable. According to the dominant Shia tradition, Husain's companions and relatives fell one by one. Among them were his half-brother Abbas ibn Ali, remembered as the standard-bearer of the camp, and his son Ali Akbar. According to these accounts, Husain's infant son Ali Asghar was killed by an arrow. Husain himself died on the battlefield. His surviving family members, including his sister Zaynab, were taken captive.
Among the few survivors were Ali Zayn al-Abidin, Husain's son, who was reportedly too ill to fight, and Hasan al-Muthanna, Husain's nephew, who survived despite severe wounds. Their survival ensured that witnesses remained who could recount what had occurred. Much of what is known about Karbala comes from a small number of early transmitters writing within roughly a century of the event. The most important is Abu Mikhnaf Lut ibn Yahya (c. 689–774 CE), a Kufan historian whose family lived among the communities most closely connected to the aftermath of the battle. His Maqtal al-Husayn, written approximately ninety years after Karbala, is the earliest known extended account of the tragedy. Although the original text no longer survives, large portions were incorporated into the works of later historians, above all al-Tabari (839–923 CE). Through Tabari's history, Abu Mikhnaf became the foundational source for much of the classical Islamic understanding of Karbala. Modern historians continue to debate details of the narrative, but virtually every reconstruction of the event—Sunni, Shia, or academic—ultimately engages with the tradition he transmitted.
The Theology of Resistance
The significance of Karbala lies not in the scale of the battle. By the standards of history, it was a small encounter in a remote corner of an empire. Its importance derives from what Muslims subsequently believed it revealed about the relationship between power and principle. For generations of Shia Muslims, Karbala became the moment when moral authority and political authority decisively diverged.
What Karbala produced in the Shia tradition was not despair. It produced a theology of resistance encoded in grief. The annual commemoration of Ashura—days of mourning, lamentation, processions, and passion plays known as ta'ziyeh—is often misunderstood by outside observers as a ritual fixation on suffering. In reality, the mourning functions as a moral recommitment. For believers, to weep for Husain is to reaffirm that power without justice is illegitimate and that conscience carries obligations even when resistance appears hopeless.
The British historian Edward Gibbon, writing in The Decline and Fall of the Roman Empire, observed that "in a distant age and climate, the tragic scene of the death of Husain will awaken the sympathy of the coldest reader." Across the centuries and civilisational divide, he recognised that Karbala possessed a significance that transcended its immediate historical context. Edward Granville Browne, the Cambridge scholar and author of A Literary History of Persia, likewise understood Karbala's enduring emotional power. Writing after decades spent studying Persian history and literature, Browne argued that the memory of Husain's death retained a unique ability to evoke moral passion and self-sacrifice long after the event itself had passed into history.
This universalism is not incidental. It explains why Karbala became a template for Shia political mobilisation across the centuries. Whenever Shia communities experienced persecution, they often interpreted their circumstances through the lens of Karbala. The oppressor became Yazid. The obligation remained Husain's.
1979: Karbala in Tehran
When Ayatollah Ruhollah Khomeini led the revolution that toppled Mohammad Reza Shah Pahlavi in February 1979, the language of the movement was saturated with references to Karbala. The Shah was frequently cast as Yazid—a ruler sustained by foreign powers and detached from justice. The revolutionaries imagined themselves as inheritors of Husain's struggle.
This was not political theatre. It reflected a longstanding current within Shia thought. The Iranian intellectual Ali Shariati had spent the 1960s and 1970s reinterpreting Ashura as a revolutionary call to action rather than merely a ritual of mourning. The slogan "Every day is Ashura, every land is Karbala" became central to this political reading of Shiism. Although its attribution to Imam Ja'far al-Sadiq remains disputed among scholars, its influence on modern Iranian political culture is undeniable.
The historian Karen Armstrong has noted that Shia Islam preserved a powerful tradition of protest against illegitimate authority. In 1979, that tradition acquired a state. The Islamic Republic institutionalised this worldview through Khomeini's doctrine of Wilayat al-Faqih—the Guardianship of the Jurist—which held that, during the occultation of the Twelfth Imam, supreme political authority should rest with a qualified Islamic jurist. The doctrine remains controversial even within Shia Islam. Yet its emotional infrastructure was unmistakably Karbala.
The Iran–Iraq War: Eight Years of Ashura
When Saddam Hussein's Iraq invaded Iran in September 1980, the Islamic Republic was barely eighteen months old. Its military was disorganised, its institutions fragile, and its leadership divided. Many observers expected a rapid Iraqi victory. Instead, Iran fought for eight years. The mobilisation drew explicitly upon Karbala symbolism. Volunteers marched to the front wearing headbands bearing the name of Husain. Martyrdom was celebrated as participation in the same moral tradition inaugurated at Karbala. The battlefields of Khuzestan were transformed into extensions of sacred history.
The war also deepened Iranian perceptions of betrayal by the international system. The United States provided intelligence, diplomatic support, and economic assistance to Iraq despite mounting evidence of Iraqi chemical weapons use. For many Iranians, the conflict reinforced an already familiar narrative: powerful states aligned themselves with oppression while Iran stood alone. Whether outsiders accept that interpretation is ultimately beside the point. What matters is that millions of Iranians understood the war through the moral vocabulary of Karbala.
The Limits of Western Analysis
For more than four decades, the relationship between Iran and the United States has been analysed primarily through the frameworks of deterrence theory, realpolitik, and strategic competition. These frameworks are useful. They are also incomplete. Iran's support for Hezbollah, its backing of allied militias across Iraq and Syria, its willingness to absorb severe economic punishment, and its cultivation of a long-term strategy of resistance all reflect a political culture shaped by memories that predate the modern nation-state.
The scholar Moojan Momen, in An Introduction to Shi'i Islam, argues that Shia political consciousness was forged across centuries of minority status, persecution, and exclusion. Rather than producing passivity, these experiences helped cultivate a moral tradition that valorised endurance and resistance. A community that has spent fourteen centuries commemorating Karbala does not necessarily respond to pressure in the ways anticipated by Western strategic theory. The Nobel laureate Seamus Heaney once observed that human beings are not governed by the present alone. They carry the dead with them. In Shia Islam, the dead of Karbala remain among the most powerful actors in political life.
The Enduring Wound
On the tenth of Muharram each year, in Tehran and Najaf and Karachi and Beirut and Lagos and London, millions gather to remember a man who chose principle over accommodation and conscience over survival. They beat their chests. They weep. They recite the names of the fallen—Husain, Abbas, Ali Akbar, Ali Asghar, Muslim ibn Aqil—not because they are trapped by grief, but because they believe grief itself carries obligations.
The lesson of Karbala is not that victory belongs to the stronger army. It is that legitimacy cannot be measured solely by power. History's verdict is not always written by those who win battles. Yazid possessed the state, the army, and the machinery of empire. Husain possessed little beyond conviction. Yet almost fourteen centuries later, Husain's name remains one of the most revered in the Muslim world, while Yazid's has become, for many Muslims, a byword for tyranny.
Anyone seeking to understand Iran must begin not with centrifuges, missile ranges, sanctions, or oil markets. They must begin on a plain in Iraq in the year 680 CE, where a man who believed a ruler unworthy of allegiance chose death rather than submission. That choice has never ceased to resonate. It grows with every generation that remembers it.
