Bābak Khorramdin (Persian: بابک خرمدین, romanized: Bābak-e Khorramdīn; 795 or 798 – January 838) was one of the main Iranian revolutionary leaders of the Iranian Khorram-Dinān ("Those of the joyous religion"), which was a local freedom movement fighting the Abbasid Caliphate. Khorramdin appears to be a compound analogous to durustdin "orthodoxy" and Behdin "Good Religion" (Zoroastrianism), and are considered an offshoot of neo-Mazdakism. Babak's Iranianizing rebellion, from its base in Azerbaijan in northwestern Iran, called for a return of the political glories of the Iranian past.
