Yazdânism
Yazdânism, or the Cult of Angels, is a pseudohistoric pre-Islamic religion with claimed ties relating to a Mithraic religion of the Kurds. The term was introduced and proposed by Kurdish and Belgian scholar Mehrdad Izady to represent what he considers the "original" religion of the Kurds.
According to Izady, Yazdânism is now continued in the denominations of Yazidism, Yarsanism, and Kurdish Alevism.
The concept of Yazdânism has found a wide perception both within and beyond Kurdish nationalist discourses, but has been disputed by other recognized scholars of Iranian religions. Well established, however, are the "striking" and "unmistakable" similarities between the Yazidis and the Yaresan or Ahl-e Haqq (People of Truth), some of which can be traced back to elements of an ancient faith that was probably dominant among Western Iranians and akin, but separate from Zoroastrianism and likened to practices of pre-Zoroastrian Mithraic religion.
