The Great Berber Revolt of 739/740–743 AD (122–125 AH in the Muslim calendar) took place during the reign of the Umayyad Caliph Hisham ibn Abd al-Malik and marked the first successful secession from the Arab caliphate (ruled from Damascus). Fired up by Kharijite puritan preachers, the Berber revolt against their Umayyad Arab rulers began in Tangiers in 740, and was led initially by Maysara al-Matghari.
