A clear, historically sourced account of the Battle of Karbala — what led to it, what happened on the day, and why it remains one of the most remembered events in Islamic history.
Introduction — An Event That Shaped Islamic History
On the 10th of Muharram, 61 AH (10 October 680 CE), a small group of people led by Husayn ibn Ali (RA), the grandson of Prophet Muhammad (peace be upon him), was killed near the Euphrates river in a place called Karbala, in present-day Iraq. This article presents the historically agreed facts of what happened, drawing on the earliest Muslim historical chronicles — primarily Tarikh al-Tabari, one of the oldest and most respected works of Islamic history, written by the scholar Imam Abu Ja'far al-Tabari in the 9th century.
It is important to note that the detailed day-by-day account of Karbala is a matter of historical record, not Hadith. Sahih al-Bukhari and Sahih Muslim — the two most authentic collections of the sayings and actions of the Prophet (peace be upon him) — were compiled to preserve Hadith, not later historical events. The story of Karbala is documented and preserved through the discipline of Islamic history (Tarikh), and the earliest and most relied-upon source for it is Tabari's history, supplemented later by Ibn Kathir's Al-Bidayah wan-Nihayah.
The Background — A Dispute Over Leadership
After the death of Muawiyah ibn Abi Sufyan, the ruler of the Umayyad state, his son Yazid ibn Muawiyah became ruler. Yazid demanded that prominent figures across the Muslim lands pledge allegiance (Bay'ah) to him. Husayn ibn Ali (RA), based in Madinah, declined to give this pledge.
The people of Kufa, in Iraq, had previously written letters to Husayn (RA), expressing their support and inviting him to come and lead them, assuring him of their backing. Acting on these assurances, Husayn (RA) set out from Makkah towards Kufa with his family and a small group of companions — accounts place the total number, including women and children, at around 70 to 90 people.
The Journey and the Change in Circumstances
While Husayn (RA) was travelling, the situation in Kufa changed dramatically. The governor appointed by Yazid, Ubaydullah ibn Ziyad, suppressed the support for Husayn (RA) in the city through pressure and intimidation. By the time Husayn (RA) and his group reached the outskirts of Kufa, the promised support had collapsed, and instead, an army was sent to intercept them.
Husayn's group was directed to a barren plain called Karbala, on the bank of the Euphrates, and was prevented from continuing their journey or returning. An army under the command of Umar ibn Sa'd, acting on the orders of Ibn Ziyad, surrounded the camp.
The Days Before Ashura
For several days, negotiations took place. Husayn (RA) offered to return to Madinah, or to go and meet Yazid directly, or to be sent to any frontier to fight — all reasonable options under the circumstances of the time. These offers were rejected; the demand was for unconditional submission to Yazid's authority.
On the night before Ashura, Husayn (RA) reportedly gathered his companions and gave them the choice to leave under cover of darkness, since the danger was directed at him specifically. According to the historical accounts, every one of his companions chose to remain.
Access to water from the Euphrates was cut off from the camp by the opposing army in the days leading up to the battle, causing severe hardship, particularly for the children in the camp.
The Day of Ashura
On the 10th of Muharram, the encounter took place. Husayn's small group — vastly outnumbered — fought through the day. One by one, his companions and male relatives were killed, including his son Ali al-Akbar and other family members. Husayn (RA) himself was killed in the latter part of the day. The women and remaining children of the camp, including Husayn's sister Zaynab (RA) and his surviving son Ali ibn Husayn (later known as Zayn al-Abidin), were taken captive and eventually transported to Kufa and then to Damascus.
Why the Event Is Remembered
The killing of the grandson of the Prophet (peace be upon him) and members of his household sent shockwaves through the Muslim world at the time and has remained a point of deep reflection across Islamic history since. For Sunni Muslims, the event is regarded as a profound tragedy and an example of the dangers of political tyranny and the value of standing by one's principles, while differing from Shia Muslims in matters of theological interpretation and ritual commemoration. The Day of Ashura itself carries independent significance in Sunni tradition tied to earlier events — including the fasting of Prophet Musa (AS) — which is the subject of a separate, Hadith-based discussion.
