Legend & origins
The pearl, again — and a God who visits
Like their Yazidi cousins in faith-geography, the Yarsan begin the world with a pearl: the divine essence hidden in the sea before time. God, they hold, is not remote — He has clothed Himself in human form seven times, and will once more.
The decisive incarnation came in the 14th century, when Sultan Sahak established the order at Perdiwar on the Sirwan river, high in the Zagros. Around him gathered seven angelic companions — the Haft Tan — and from that gathering descends every Yarsani lineage. The soul, they teach, migrates through a thousand and one bodies on its way to purity; the world is a garment God puts on and off.
Theology lives in the Kalâm-e Saranjâm, “the Discourse of Conclusion,” composed in Gorani verse — and it is sung. Doctrine passes at nightly gatherings called jam, where the sacred tanbur lute accompanies hymns the uninitiated will never hear explained. Like the Druze and the Alevis, the Yarsan learned that survival favours the discreet: their first rule, sirr-e mgo — “do not tell the secret.”
What sets them apart
A theology you can only hear
Everything distinctive about the Yarsan flows from one choice: to make music, not text, the vessel of revelation — and secrecy, not mission, the shield of the community.
The jam and the tanbur
The weekly gathering blends sung kalâm, the sharing of consecrated food, and the lute whose seventy-two strings' predecessors are named in scripture. Master players like Ostad Elahi became figures of world music without the world knowing the faith behind them.
The moustache commandment
Traditional Yarsani men do not trim the moustache — a marker so distinctive that in both Ottoman and Ba'athist files, the community appears as “the moustached ones.”
Dun-a-dun — the migrating soul
The soul passes garment to garment through 1,001 lives toward the divine; hell is not a place but a failed journey.
Born, not converted
Like the Druze and Yazidis, the Yarsan accept no converts; one is born into a spiritual lineage tied to one of the founding families of Perdiwar.
Iran & Iraq today
Between erasure and the census
Iran's constitution recognises Christians, Jews and Zoroastrians — not the Yarsan. Officially most are counted as Shia Muslims; practically they navigate surveillance, occasional desecration of shrines, and periodic protest: in 2013, self-immolations by Yarsani men in Hamadan after moustache-shaving humiliations in prison briefly forced the community into national news.
In Iraq, where the community is called Kaka'i, the pressure has been physical. Their villages south-east of Mosul and around Kirkuk sat directly on ISIS's path; shrines were mined, families displaced, and Kaka'i units fought within the Peshmerga. Some Kaka'i now press for recognition as a distinct religion in Iraqi law — others prefer the old shield of being counted as Muslims, and quiet.

Through time
Timeline
- 14th centurySultan Sahak at Perdiwar. The faith's constitutive incarnation; the Haft Tan gather and the lineages are founded.
- 16th–19th c.The quiet centuries. Yarsan communities survive between Ottoman and Persian empires by discretion, paying the price of periodic persecution as “extremist Shia.”
- 20th centuryPartial emergence. Ostad Elahi carries the tanbur repertoire toward the concert hall; urban migration loosens village secrecy.
- 2013The moustache protests. Self-immolations in Iran after prison humiliations force rare public attention.
- 2014–17ISIS and the Kaka'i. Iraqi Kaka'i villages are occupied and shrines destroyed; community units fight with the Peshmerga.
- TodayRecognition unresolved. Uncounted in Iran, newly assertive in Iraq — the largest faith in this atlas without any legal existence.

No state counts the Yarsan; scholarly estimates for Iran alone range from one to over three million. Figures shown are mid-range.

What they gave the region
Masters of the sacred string
The Yarsan gave the region one of its great musical traditions: the tanbur repertoire — sacred maqams passed master to disciple since the middle ages — entered the world's concert halls through Ostad Elahi and Kurdish masters like Ali Akbar Moradi, and now shapes the sound of Iranian and Kurdish art music far beyond the faith. Kermanshah's workshops still build the instrument to medieval patterns.
Yarsani verse — the kalâm corpus in Gorani — is also one of Kurdish literature's oldest bodies of poetry, studied now as a key to the region's pre-Islamic religious undergrowth.
Looking forward
Out of the shadow of secrecy
A generation of Yarsani activists is testing whether sirr-e mgo — 'do not tell the secret' — still serves. In Iraq, Kaka'i leaders press for recognition as a distinct religion with protected villages; in Iran, where the constitution offers no box for them, the community weighs visibility against reprisal after each protest. Migration to Europe has created, for the first time, Yarsani institutions beyond any state's reach.
The tanbur may prove the faith's best ambassador: easier to love than to persecute, it carries the theology across borders one recording at a time.
The emblem
The tanbur
No symbol could be more Yarsani than the instrument itself: the pear-bodied, long-necked tanbur, whose sound the community calls the voice of the unseen. Scripture is sung to it; saints played it; masters are buried with it.
