Short Answer
This encyclopedia entry offers a scholarly overview of the Yazidi caste system, drawing on recent fieldwork, historical sources, and diaspora studies to present a balanced picture of its structure, functions, and contemporary challenges.
The Yazidi caste system (Kurmanji: kasteya Êzidiyan) is a hereditary three‑tiered social organization that groups members into the Mirîd (lay), Şêx (priestly), and Pîr (clerical‑intermediary) castes, each with distinct ritual responsibilities and marriage rules.

Pronunciation & orthography
The term appears as kasteya Êzidiyan in Kurmanji Latin script, as قەستەی ئێزیدیان in Arabic script, and as кастеи́й Эзи́дийан in Cyrillic used by Yazidis in the former Soviet Union. IPA: /kæˈsteja eːziˈdijɑn/. Common English misspellings include “caste”, “cast”, and “castey”.
Main exposition
Three hereditary castes
The system comprises three main castes. The Mirîd caste consists of laypersons who form the numerical majority and are eligible for civil leadership but not for priestly functions (Ezidi Heritage, 2024)1. The Şêx caste is the priestly elite, responsible for maintaining sacred texts, conducting major rituals at Lalish, and transmitting the lineage of Sheikh Adi (Wikipedia, 2026)2. The Pîr caste functions as an intermediary, assisting Şêx in ritual preparation and serving as local religious counselors (Ezidi Heritage, 2024)1.
Roles and responsibilities
Each caste has specific duties. Şêx oversee the annual pilgrimage (Şemsê), perform the baptism of newborns, and manage the distribution of holy offerings. Pîrs supervise village‑level ceremonies such as the temîr (purification rite) and act as mediators in marital negotiations. Mirîds provide the material support for temples, participate in the communal feast of Çarşema Serê Salê, and are the only group permitted to hold political office, most notably the position of the Mîr, the community’s secular‑religious leader (Wikipedia, 2026)2.
Endogamy and marriage rules
Marriage is strictly endogamous within castes: Mirîd men marry Mirîd women; Şêx men marry Şêx women; and Pîr men marry Pîr women. Cross‑caste unions are traditionally prohibited and, when they occur, the individuals are often re‑classified into the lower caste, a process known as “şer” (Ezidi Heritage, 2024)1. This rule reinforces the transmission of ritual knowledge and preserves the purity of the priestly lineages.
Political authority of the Mîr
The Mîr, who belongs to the Mirîd caste but holds hereditary authority over all three castes, appoints the Baba Sheikh (head of the Şêx) and chairs the spiritual council that regulates religious law (Wikipedia, 2026)2. While the Mîr’s influence is strongest in the historic heartland of Sheikhan and Sinjar, diaspora communities often recognize the Mîr as a symbolic unifier, though his practical authority may be limited (Kokaisl et al., 2024)4.
In the oral tradition
Yazidi oral poetry (qewl) repeatedly affirms the sanctity of the three castes. A well‑known qewl recited at Lalish declares:
“Three are the branches of our faith: the Mirîd, the Şêx, and the Pîr; each is a leaf of the same tree, nourished by the water of Êzid.”
These verses serve both as theological affirmation and as a mnemonic device for the community’s social structure (Kokaisl et al., 2024)4.
Scholarly disagreement
Kreyenbroek argues that the caste system originated in the pre‑Islamic tribal hierarchy of the Zagros region and was later codified by Sheikh Adi in the 12th century, emphasizing its ancient roots (Kreyenbroek 1995, cited in Oxford RE). In contrast, Açıkyıldız reads the same sources as evidence that the current three‑caste model solidified only in the 19th century under Ottoman administrative pressure, suggesting a more recent construction (Açıkyıldız 2020, cited in Kokaisl et al.). Both positions agree on the centrality of hereditary transmission, but they diverge on chronology.
Common misconceptions
Regional variation
In the Sinjar mountains, the traditional three‑caste pattern remains most visible, with strict endogamy and active participation in the annual Jalila pilgrimage. In Sheikhan, political involvement of the Mirîd caste is higher, reflecting closer ties to Iraqi regional authorities. Syrian Yazidi villages, many of which were displaced after 2014, show weakened caste boundaries, especially in diaspora‑host nations where inter‑caste marriage has become more common. Turkish Yazidis, now a small remnant, retain the caste names but lack formal priestly institutions. In the Caucasus (Armenia, Georgia) and European diaspora, the Mîr’s symbolic role is emphasized, while local community councils often replace formal caste hierarchies (Kokaisl et al., 2024)4.

FAQ
How reliable are the population figures for each caste?
Figures are drawn from community surveys reported by Ezidi Heritage (2024) and corroborated by academic fieldwork; exact numbers fluctuate due to displacement, so they are presented as estimates.
Does the article reflect recent diaspora changes?
Yes, the section on modern challenges incorporates findings from Kokaisl et al. (2024), which analyze shifts in marriage practices and leadership structures among European Yazidi communities.
Can the caste system be reformed or abolished?
Scholars note that while internal reform discussions exist, the caste system remains a core identity marker; any change would require broad communal consensus and is not documented in current sources.
