[1] Although many scholars consider his name to be derived from that of the second Umayyad caliph Yazid I, Yazidis consider him to be a separate figure unconnected to the historical Yazid I.
[2] Yazidis typically consider him to be part of a triad of divine emanations of God (which are, in order, Melek Tawus, Sheikh Adi, and Sultan Ezid),[3] though he is sometimes also considered to be identical with the angel Melek Tawus, and thus a manifestation or emanation of God.
[5] In Yazidi religious lore, there is no trace of any link between Sultan Ezid and the second Umayyad caliph.
[6] The Adawiyya existed in the Kurdish mountains before the 12th century, when Shaykh Adi,[7] a Sufi of Umayyad descent venerated by Yazidis to this day,[8] settled there and attracted a following among the adherents of the movement.
The name Yazidi seems to have been applied to the group because of his Umayyad origins.
