The Battle of Karbala took place on Muharram 10, in the year 61 AH of the Islamic calendar (October 10, 680 AD)a in Karbala, in present-day Iraq.
The battle took place between a small group of supporters and relatives of Muhammad’s grandson, Husayn ibn Ali, and a larger military detachment from the forces of Yazid I, the Umayyad caliph.
When Muawiyah I died in 680, Husayn did not give allegiance to his son, Yazid I, who had been appointed as Umayyad caliph by Muawiyah; Husayn considered Yazid’s succession a breach of the Hasan–Muawiya treaty. The people of Kufa sent letters to Husayn, asking his help and pledging allegiance to him, but they later did not support him. As Husayn traveled towards Kufa, at a nearby place known as Karbala, his caravan was intercepted by Yazid I’s army led by Al-Hurr ibn Yazid al Tamimi.
He was killed and beheaded in the Battle of Karbala by Shimr Ibn Thil-Jawshan, along with most of his family and companions, including Husayn’s six month old son, Ali al-Asghar, with the women and children taken as prisoners. The battle was followed by later uprisings namely, Ibn al-Zubayr, Tawwabin, and Mukhtar uprising which occurred years later.
