Kharijites

The Kharijites (, singular ) were an Islamic sect which emerged during the First Fitna (656–661). The first Kharijites were supporters of Ali who rebelled against his acceptance of arbitration talks to settle the conflict with his challenger, Mu'awiya, at the Battle of Siffin in 657. They asserted that "judgment belongs to God alone", which became their motto, and that rebels such as Mu'awiya had to be fought and overcome according to Qur'anic injunctions. Ali defeated the Kharijites at the Battle of Nahrawan in 658, but their insurrection continued. Ali was assassinated in 661 by a Kharijite dissident seeking revenge for the defeat at Nahrawan.

After Mu'awiya established the Umayyad Caliphate in 661, his governors kept the Kharijites in check. The power vacuum caused by the Second Fitna (680–692) allowed for the resumption of the Kharijites' anti-government rebellion, and the Kharijite factions of the Azariqa and Najdat came to control large areas in Persia and Arabia. Internal disputes and fragmentation weakened them considerably before their defeat by the Umayyads in 696–699. In the 740s, large-scale Kharijite rebellions broke out across the caliphate, but all were eventually suppressed. Although the Kharijite revolts continued into the Abbasid Caliphate (750–1258), the most militant Kharijite groups were gradually eliminated. They were replaced by the non-activist Ibadiyya, who survive to this day in Oman and some parts of North Africa. They, however, deny any links with the Kharijites of the Second Muslim Civil War and beyond, condemning them as extremists.
