Tarikh Islam

Kharijites were an influential group in the events of first centuries ('AH'), which was first developed as an independent sect during Imam Ali's Caliphate and the battle of Siffin and opposed the idea of going to arbitration. When 'Umayyads took Caliphate, Khawarij sparked many uprisings against them, so they were being sued by 'Umayyad rulers. This made them relocate their activities in some regions far away from the center of Caliphate, including north west of Iran and Sistan. With the help of the local people of this region, Khawarij continued their military operations against 'Umayyads and 'Abbasids for about three centuries. At the end, they could not maintain their consistency and, as a result, transmuted into local people. The main question is: why did Khawariji ideas not last in Sistan? The reasons behind their failure in this regard seem to be: their use of violence and terror, their being subject to suppression by 'Umayyads, superiority of their combating wing over their ideological wing, and their inability to conform to the native culture of Sistan.
