The Khurramites (Persian: خرمدینان‎‎ Khorrām-Dīnān, meaning "those of the Joyful Religion"; Arabic: خُرَّمِيَة‎‎ Khurramiyya) were an Iranian[1][2][3] religious and political movement with its roots in the movement founded by Mazdak.[3] An alternative name for the movement is the Muḥammira (Arabic: محمرة‎‎, "Red-Wearing Ones"; in Persian: سرخ‌جامگان‎‎ Surkh-Jāmagān), a reference to their symbolic red dress.
