Бабек
The 9th century also saw the revolt by native Zoroastrians, known as the Khurramites, against oppressive Arab rule. The movement was led by a Persian freedom fighter Babak Khorramdin. Babak's Iranianizing rebellion, from its base in Azerbaijan in northwestern Iran, called for a return of the political glories of the Iranian past. The Khorramdin rebellion of Babak spread to the Western and Central parts of Iran and lasted more than twenty years before it was defeated when Babak was betrayed by Afshin, a senior general of the Abbasid Caliphate.
