Khurramites

The Khurramites (Persian: خرمدینان Khurram-Dīnân, meaning "those of the Joyful Religion") were an Iranian religious and political movement with roots in the Zoroastrian movement of Mazdakism. An alternative name for the movement is the Muhammira (Arabic: محمرة, "Red-Wearing Ones"; in Persian: سرخ‌جامگان Surkh-Jâmagân), a reference to their symbolic red dress.

According to Abdülbaki Gölpınarlı, the Qizilbash ("Red-Heads"') of the 16th century – a religious and political movement in Iranian Azerbaijan that helped to establish the Safavid dynasty – have been described as "spiritual descendants of the Khurramites".
