Yezidism (Yazidism)

← Encyclopedia

Yezidism is the religion of the Yazidis, a Kurmanji-speaking people whose historic heartland lies in northern Iraq — the Sinjar mountains and the Shaykhan district north of Mosul — with older communities in Syria, Turkey, and the Caucasus and a large modern diaspora, above all in Germany, where roughly a hundred and fifty thousand now live. It is a closed religion: a Yazidi is born, never made; marriage outside the community is forbidden; and every member belongs by birth to one of three hereditary classes — sheikhs, pirs, and the murid laity — bound to one another by lifelong religious obligation. No one converts in and no one is born out. The line of belonging runs through blood and through the assigned spiritual kinship that ties each murid household to a particular sheikh and a particular pir, who carry the religious knowledge that the laity, for the most part, do not. To be Yazidi is to stand inside that web of descent and obligation; it is not a creed one can adopt.

The Peacock Angel and the angel who never fell

At the center of Yezidi theology stands Tawûsê Melek, the Peacock Angel. One God — Xwedê — made the world and withdrew above its workings, entrusting its governance to seven holy beings, the Heft Sirr, the Seven Mysteries, with the Peacock Angel at their head. These seven are the cosmocrators of the world, the hands through which the distant creator administers what he has made; the angel here is no messenger or attendant but a delegated power, a vicegerent over creation. The transcendent God is not the object of daily devotion. He is too high, too unengaged, to be approached directly. It is the heptad, and above all their chief, who receive the prayers, hold the festal calendar, and bind heaven to the valley of Lalish.

The myth that has shadowed the Yazidis turns on a single scene, told in the qewl hymns and echoed in the late prose texts. God formed Adam from clay and commanded the seven to bow before him. Tawûsê Melek alone refused — and refused not from pride but from fidelity. God had decreed first, before any creature was made, that worship belongs to God alone; the later command to bow before Adam was a test, and the Peacock Angel held to the prior word against the later. For that obedience-mistaken-for-disobedience he was not cast down but exalted, made God’s deputy on earth and lord of the seven.

To a Muslim or Christian ear the scene rang familiar and wrong. The Qur’an tells how Iblis, commanded to prostrate before Adam, refused — and fell, cursed, becoming the tempter. Hearing the Yazidi angel refuse the same command, neighbors collapsed the two figures into one and concluded that the Yazidis worshipped the devil. The inversion is precise and it is total. Where Iblis falls through a disobedience he dresses as fidelity, Tawûsê Melek rises through a fidelity that outsiders read as disobedience. In the doctrinally proper Yezidi telling there is no fall at all, and the “devil-worshipper” name is not a description but a slander — a Muslim and Christian Orientalist construction read onto a theology it inverts. Yazidis reject the identification absolutely. In their cosmos no rival power stands against God to be feared or appeased, and the very name of the evil one is not permitted to pass Yazidi lips — a taboo so strict that words merely resembling shaytan are avoided in speech, and the foreign equation of their angel with that name compounds the insult by violating the taboo at its root. The misreading has carried a long bill. Yazidi memory numbers the community’s persecutions at seventy-two — ferman, the Ottoman word for an edict of slaughter — and the seventy-third, the assault on Sinjar in 2014, is only the most recent.

A born religion and its three estates

The closed, born-into structure is not incidental to Yezidism; it is its architecture. Society divides into two priestly lineages, the sheikhs and the pirs, and the murid laity they serve. The divisions are themselves subdivided into lineages tracing descent from the holy figures of the formative age, and a murid may not marry into a sheikh or pir family any more than a Yazidi may marry a non-Yazidi; the three estates intermarry only within themselves. Religious knowledge — the qewls, the genealogies, the meaning of the rites — is held by the priestly castes, transmitted in the family rather than the school, so that the faith is carried less as a body of doctrine to be taught than as an inheritance to be kept. Two further offices stand at the apex: the Mîr, the hereditary prince who is the community’s temporal head, and the Baba Sheikh, the chief of the sheikhs and the religion’s spiritual authority. Both reside in the Shaykhan region, near the sanctuary.

This shape — a transcendent God, a delegated heptad, an esoteric knowledge guarded by hereditary priests, an endogamy that forbids conversion as a matter of theology rather than mere custom — places Yezidism within a wider family of late-antique Mesopotamian and Iranian survivals. The Mandaeans of the southern marshes, with their own hereditary priesthood, their cosmic Seven, their water rites, and their refusal of converts, are the nearest living cousin; the extinct Manichaeans, the Yaresan, and the Alevi belong at varying removes to the same matrix. The shared features — dualistic structuring, a guarded esoteric knowledge, a cosmic seven, water and baptism, reincarnation, the refusal of conversion — are not signs that one tradition borrowed from another. The distances of language, geography, and confession are too great for that. They are the common inheritance of a late-antique Iranian-Mesopotamian religious world that fed many downstream streams without any of them drinking from the others.

Sheikh ʿAdī and the twelfth-century hinge

The religion has a securely datable hinge. Sheikh ʿAdī ibn Musāfir (c. 1073–1162) was a Sufi of wide reputation, born in the Bekaa and trained in Baghdad in the great age of Sufi consolidation — in the circle of ʿAbd al-Qādir al-Jīlānī and of the brothers of al-Ghazālī. He withdrew into the Hakkârî mountains and settled in the valley of Lalish, gathering an order around him, the Adawiyya. The medieval Arabic chroniclers — Yāqūt, Ibn al-Athīr, Ibn Khallikān — record him as an unambiguously orthodox Sunni ascetic, and the Arabic works that survive under his name show no heterodoxy. He died about 1162 and was buried at Lalish.

The transformation came after him. Under his successors — above all Sheikh Ḥasan ibn ʿAdī in the thirteenth century — the Sufi order in the mountains became something else: not a tariqa with local color but a self-standing religion, with its own scripture-cluster, its hereditary priesthood, a liturgical calendar tied to the Iranian solar year, and an ethnoreligious self-understanding under which no outsider could enter. The destruction of ʿAdī’s tomb in the mid-thirteenth century and the charge, leveled by Muslim neighbors, that the order venerated Yazīd ibn Muʿāwiya — the Umayyad caliph reviled in Shīʿī memory, honored here as Sultan Êzîd — mark the rupture as complete by the fourteenth century. The Adawiyya entered the mountains a Sunni brotherhood; what emerged, generations on, was a different faith. Within that faith Sheikh ʿAdī is no mere founder but a manifestation of the divine, and his tomb at Lalish — its fluted conical spire rising over the valley — is the holiest place in the religion: the site of baptism in the White Spring and of the autumn Feast of the Assembly, the Cejna Cemaʿiyye, when the scattered community gathers for seven days in the valley.

What walked out of the Hakkârî was not Sufism with a new face but a religion built on a much older stratum. On the standard scholarly account the Adawiyya, planted among the mountain Kurds, met and partly absorbed a pre-Islamic religious complex that preserved genuine Iranian and Mesopotamian material: prayers turned toward the rising sun, lamps lit at the New Year, the sanctity of flowing water, the transmigration of souls. Philip Kreyenbroek has argued that this older layer descends from a western Iranian religion related to, but distinct from, the faith of Zoroaster — a separate branch off the same Iranian root rather than a corruption of Mazdeism — and that the Yezidi cosmogony, with its cooperating rather than warring divine agents, preserves an archaic Iranian myth-pattern of its own. The thesis is influential and is not unchallenged; a rival reading, associated with Garnik Asatrian and Victoria Arakelova, presses the Sufi-Islamic side harder and reads the Peacock Angel as closer to the redeemed Iblis of the Hallajian Ṭawāsīn — a view its critics judge an overcorrection. The registers are best kept apart: what the tradition holds of itself, what the medieval record documents of Sheikh ʿAdī, and what philology reconstructs of the substrate are three different kinds of claim.

The sung scripture and the soul that changes its shirt

The authentic body of Yezidism is not written but sung. Its core is the corpus of qewls — sacred hymns, with their attendant beyts, prayers, and ritual formulas — transmitted by a special caste of reciters, the qewwals, drawn chiefly from the villages of Baʿshiqa and Baḥzane and performed to the sacred instruments at the great festivals. The qewls carry the cosmogony, the holy genealogies, and the theology, held in memory and voice across the centuries and only recently set down on paper by scholars. Against this living oral core stand two short Arabic prose books that present themselves as Yazidi scripture — the Kitêbâ Cilwe, the Book of Revelation, and the Mishefa Reş, the Black Book — which surfaced in manuscripts circulating in Mosul late in the nineteenth century. The scholarly judgment, settled across the major modern studies, is that these prose texts are late compilations, very likely the work of Christian intermediaries in Mosul writing partly in answer to a European appetite for a Yazidi “holy book”; a purported “original Kurdish” version announced in 1911 was shown by Alphonse Mingana to be a fabrication. Yet the compilers had real access to oral tradition, so the books encode authentic material even where they are not the sect’s living scripture. The distinction matters: the religion’s true text is the qewl in the qewwal’s mouth, not the prose forgery in the orientalist’s library.

Among the doctrines the qewls carry is the journey of the soul. At death the soul does not depart for a final judgment but passes into another life, reborn in a new body. The Yazidi idiom names it kiras guhorîn — changing the shirt: the soul lays aside one garment of flesh and puts on another, the body a vestment worn and discarded while the wearer endures. The same logic governs the holy figures, who descend into successive earthly manifestations across the ages. This transmigration sets Yezidism apart from its Muslim and Christian neighbors and aligns it with the Yaresan and with the older Iranian and Indian currents of rebirth.

Even the religion’s name is unsettled. Some derive Êzîdî from Sultan Êzîd — that is, from the caliph Yazīd, venerated in the tradition though reviled outside it — making the Yazidis “the people of Yazīd”; others derive it from an old Iranian word, yazata or yazd, for a divine being, so that the name means simply “the worshippers of God” or “those given to the divine.” The two etymologies pull in different directions — one toward the Umayyad caliphate, one toward the Iranian substrate — and the dispute mirrors the larger question of where the religion’s deepest roots lie.

The seventy-third ferman

On the third of August 2014, the forces of the Islamic State swept into Sinjar. What followed was determined by the United Nations, and by some eighteen national governments and supranational bodies after it, to be a genocide. Men were massacred — the village of Kocho lost its entire male population on the fifteenth of August — and thousands of women and girls were carried off into slavery and sold. Around five thousand were killed; thousands of women and children were abducted; more than two hundred thousand were driven from their homes, so that by 2015 some seventy percent of the world’s Yazidis had been displaced, and thousands of the captured remain missing a decade on. The UN Commission of Inquiry’s report, They came to destroy, was the first international body to name it genocide; the first criminal conviction for the genocide of Yazidis came at Frankfurt in 2021. Nadia Murad, a survivor of Sinjar who became the witness of her people before the world, was awarded the Nobel Peace Prize in 2018.

The catastrophe shifted the religion’s center of gravity. Its heartland endures — Lalish receives its pilgrims, the autumn Assembly gathers in the valley, a Mîr and a Baba Sheikh hold their offices in Shaykhan — but the largest community now lives in Germany, and Yazidis are scattered across Sweden, Canada, the United States, and Australia, an ancient closed religion learning to keep its blood-borne, untransmittable faith in the cities of exile. The seventy-two persecutions counted in memory were the long rehearsal for the seventy-third, and the question every ferman has posed — whether a people that admits no converts can outlast the killing of its members — is one the lamps relit each spring and the qewls carried in unforgetting tongues continue to answer. The religion’s own account of itself is sung rather than written, and its center remains the valley of Lalish.

Sources and scholarship

The contemporary study of Yezidism rests on a small number of close-worked critical studies, nearly all in copyright. Philip G. Kreyenbroek’s Yezidism: Its Background, Observances and Textual Tradition (Lewiston: Mellen, 1995) established the framework within which the religion is now read, including the western-Iranian-substrate thesis; his collaboration with Khalil Jindy Rashow, God and Sheikh Adi are Perfect: Sacred Poems and Religious Narratives from the Yezidi Tradition (Wiesbaden: Harrassowitz, 2005), is the standard critical edition of the central qewl corpus. Christine Allison’s The Yezidi Oral Tradition in Iraqi Kurdistan (Richmond: Curzon, 2001) treats the living tradition of recitation, and her synthesizing overview of the Yazidis in the Encyclopaedia Iranica is the most accessible scholarly entry point. Eszter Spät’s Late Antique Motifs in Yezidi Oral Tradition (Piscataway: Gorgias, 2010) and Birgül Açıkyıldız’s The Yezidis: The History of a Community, Culture and Religion (London: I.B. Tauris, 2010) extend the textual and historical apparatus, while John S. Guest’s Survival Among the Kurds (London: Routledge, 1993) gathers the documentary history of persecution.

The older European corpus is uneven and must be read against its frame. Austen Henry Layard’s account of the autumn pilgrimage at Lalish, in Nineveh and Its Remains (1849), is among the most-cited early eyewitness descriptions, though its subtitle encodes the “devil-worshipper” label; George Percy Badger’s inquiries in The Nestorians and Their Rituals (1852) and the E. G. Browne translation of the prose “sacred books” appended to Oswald Parry’s Six Months in a Syrian Monastery (1895) are foundational and equally entangled in the Orientalist framing. Isya Joseph’s Devil Worship: The Sacred Books and Traditions of the Yezidiz (Boston, 1919), still cited for its Arabic recension, defends the very slander its sources spread, and stands as a document of the authenticity controversy rather than a neutral witness — its full text is freely available. For the present, the determinative document is the United Nations Human Rights Council’s report on the genocide, They came to destroy: ISIS Crimes against the Yazidis (2016), which moved the community’s modern catastrophe from rumor to adjudicated fact.
