Turkish scholar Abdülbâkî Gölpınarlı sees even the Qizilbash of the 16th century – a radical Shi'i movement in Persia which helped the Safaviyya establish Twelver Islam as the dominant religion of Iran – as "spiritual descendants of the Khurramites" and, hence, of the Mazdakites. "Mazdakist" eventually seems to have become a standard derogative label attached by pre-modern Persian and Arabic authors to any radical egalitarian movement in subsequent Iranian history. While medieval Muslim historiography primarily focused on the "socialist" aspects of Mazdak, Zoroastrian tradition, on the other hand, remembers Mazdak above all as a dangerous heretic and enemy of the true faith ("Zand-i Wahman yasn" 2:1).
