Second Fitna: The Battle of al-Harra was fought between Umayyad forces and the rebel defenders of Medina at a lava field northeast of the city.

The Second Fitna was the second civil war in the Islamic community during the early Umayyad Caliphate. It followed the death of the first Umayyad caliph Mu'awiya I in 680, and lasted for about twelve years. The war involved three main challenges to the authority of the Umayyad dynasty; the first by Husayn ibn Ali, as well as his supporters including Sulayman ibn Surad and Mukhtar al-Thaqafi who rallied to avenge his death in Iraq, the second by Abd Allah ibn al-Zubayr who proclaimed himself caliph in Mecca and was nominally recognized throughout most of the Caliphate, and the Kharijites who took over central Arabia and southern Iraq and Persia.
