Short Answer
This encyclopedia entry surveys the organization of religious leadership among three Kurdish‑linked minority faiths: Yazidism, the Ahl‑i Haqq (Yarsanism), and Kurdish Alevism. By comparing titles, transmission modes, and regional specificities, the article illuminates how each tradition sustains continuity and adapts to modern challenges.
Clergy hierarchy (Kurmanji: hêzê pêşdîtî) refers to the structured system of religious authority that governs ritual, doctrinal transmission, and community governance within a faith tradition.

Main exposition
Yazidi clergy
The Yazidi religious hierarchy is anchored by the Baba Sheikh, the supreme spiritual authority, who is traditionally selected from the lineage of the Sheikh‑Adan family. Below the Baba Sheikh are two hereditary ranks: Sheikhs (spiritual guides for particular villages) and Pirs (caretakers of holy sites and mediators of ritual). Leadership is transmitted through patrilineal descent, reinforced by oral instruction of sacred rites and the memorization of the Qewl corpus. The 2018 study on minority religious leadership notes that the Yazidi clergy’s authority has been both challenged and reinforced in the aftermath of the IS‑led genocide, highlighting a resilient but vulnerable structure (Leezenberg 2018).2
Yarsani (Ahl‑i Haqq) clergy
Yarsani religious guidance centers on hereditary Sayyids (spiritual masters) who claim descent from the founding figure Sultan Sahak. These Sayyids are assisted by Mawlawi scholars trained in the oral transmission of sacred poetry (Gahira) and the Kalâm-e‑Saheeh. Kreyenbroek (2022) emphasizes that Yarsani authority is less institutionalized than in Yazidism; instead, authority flows through recognized carriers of the oral tradition, who are granted legitimacy by community consensus and lineage (Kreyenbroek 2022).3
Kurdish Alevi clergy
Alevis organize around the figure of the Dede (or Baba), a spiritual elder who conducts cem ceremonies, interprets the Buyruk, and mediates between the community and the divine. The Dede’s authority is typically acquired through apprenticeship under a senior Dede and is reinforced by the performance of the semah ritual. Gültekin (2019) observes that Kurdish Alevis have adapted the Dede role to contemporary contexts, creating “new ways of practicing” that blend traditional authority with modern civil society structures (Gültekin 2019).4
Comparative overview
All three traditions share a reliance on hereditary or lineage‑based transmission, yet they differ in institutionalization. Yazidism possesses a clearly defined three‑tiered hierarchy culminating in the Baba Sheikh. Yarsanism’s leadership is more fluid, anchored in the charismatic authority of Sayyids and oral scholars. Kurdish Alevism, while also hereditary, allows for greater communal negotiation of Dede legitimacy, especially in diaspora settings.
In the oral tradition
Oral poetry functions as the backbone of clerical legitimacy. For Yazidis, the Qewl (sacred hymns) are memorized by Sheikhs and Pir‑sheikhs, who recite them during pilgrimages to Lalish. A typical verse underscores the Sheikh’s role as a conduit of divine truth:
“He who knows the secret of the Seven, the Sheik shall guide the flock”.
(Kreyenbroek 2022).3 Yarsani Sayyids preserve the Kalâm-e‑Saheeh through melodic recitation, a practice described by Kreyenbroek as the “living scripture” of the Yārsān. Alevis’ Dedes chant the Buyruk in cem gatherings, reinforcing communal identity; Gültekin notes that these recitations have been digitized in diaspora communities to ensure continuity (Gültekin 2019).4
Scholarly disagreement
Martin van Bruinessen argues that Ahl‑i Haqq religious authority retains a distinctly Iranian‑Zoroastrian imprint, emphasizing the priestly class’s role in preserving pre‑Islamic cosmology (Bruinessen 2019).1
Philip G. Kreyenbroek counters that the Yarsani’s leadership is primarily Kurdish‑based and that the Iranian influence is overstated; he stresses the centrality of Kurdish oral poetry in legitimizing Sayyids (Kreyenbroek 2022).3
Ahmet Kerim Gültekin contends that contemporary Kurdish Alevis have moved beyond the strictly hereditary Dede model, incorporating elected community elders, especially in urban diaspora contexts (Gültekin 2019).4
Common misconceptions
Regional variation
In Iraq’s Sinjar and Sheikhan districts, Yazidi clergy maintain close ties to the Lalish sanctuary, and the Baba Sheikh’s authority is widely recognized. In the Kurdish diaspora (Germany, Sweden), informal councils of Sheikhs supplement the Baba Sheikh’s guidance, reflecting adaptation to secular legal frameworks. Yarsani communities in Iran’s Kermanshah province preserve the Sayyid lineage, while those in Iraqi Kurdistan employ a more decentralized network of Mawlawi scholars. Kurdish Alevis in Turkey’s Tunceli region retain traditional Dede lineages, whereas Alevis in the Caucasus and European diaspora have introduced elected “cemevi committees” alongside hereditary Dedes, as noted by Gültekin (2019).4

FAQ
How reliable are the population figures for these minority groups?
Population estimates are derived from scholarly surveys and fieldwork; they vary widely because many communities avoid official censuses. The figures quoted reflect the ranges reported in recent academic literature (see Kreyenbroek 2022).
Do all Yazidis follow the same clergy hierarchy?
While the three‑tiered system (Baba Sheikh, Sheikh, Pir) is the normative model, local variations exist, especially in diaspora communities where informal councils supplement traditional authority.
Can a non‑hereditary individual become a Dede in Kurdish Alevism?
Traditional Alevi doctrine emphasizes hereditary transmission, but recent studies (Gültekin 2019) document the emergence of elected community elders who perform Dede functions alongside hereditary leaders.
