# Hidden 'crypto-Jews,' the descendants of the Dönme, secretly ran the Young Turk revolution, founded the Turkish Republic, and covertly control Turkey's politics and media

**Verdict: Contradicted.** This is a debunked antisemitic conspiracy theory, and its verdict is locked accordingly. It starts from a real community: the Dönme, descendants of the 17th-century followers of the false messiah Sabbatai Zevi, who converted to Islam alongside him in 1666 and were historically centered in Ottoman Salonica. That history is genuine and is treated here with respect. The false leap is the modern conspiracy stacked on top of it: that hidden Dönme 'crypto-Jews' secretly engineered the 1908 Young Turk revolution, covertly founded and control the secular Turkish Republic (with Mustafa Kemal Atatürk and later leaders recast as concealed Jews), and pull the strings of Turkish politics and media today. No evidence supports any coordinating cabal. Scholars including Marc David Baer, Rifat Bali, and Türkay Salim Nefes, and monitoring bodies such as the Moshe Dayan Center, document this as a central strand of modern Turkish antisemitism, drawing on the forged Protocols of the Elders of Zion, that has been amplified by bestselling books and pro-government media in a country whose Jewish population now numbers only in the low tens of thousands. We report the smear as the hoax it is; we never assert it and never target the community it maligns.

Category: Secret Societies & Power · Era: 17th–21st century · First circulated: The accusation took shape in the wake of the 1908 Young Turk revolution, whose leadership emerged from cosmopolitan Salonica, and was fed by the Protocols of the Elders of Zion as it spread in Turkey through the 20th century. It reached a mass modern audience with Soner Yalçın's 2004 bestseller 'Efendi: The Great Secret of the White Turks' and the wider 'crypto-Jew' publishing wave of the 2000s. · Believed by: A widely circulated conspiracy narrative in Turkey rather than a fringe one, promoted across Islamist, ultranationalist, and secular-nationalist writing and amplified at times by pro-government media. Survey and interview research by Türkay Salim Nefes finds right-wing parties invoking it while liberal and left parties distance themselves. Historians, sociologists, and the descendants of the community reject it as antisemitic pseudoscience.

## Summary
The Dönme 'crypto-Jew' conspiracy takes a small, real religious community and turns it into an all-powerful secret hand behind the Turkish state. The Dönme are genuine: descendants of Jews who followed the self-proclaimed messiah Sabbatai Zevi into conversion to Islam in 1666 and who lived for centuries as an endogamous community in Salonica, keeping some Jewish-rooted traditions in private while practicing Islam in public. From that real history a false claim is built: that hidden Dönme secretly orchestrated the 1908 Young Turk revolution, covertly created and run the secular Republic, and control Turkey's politics and press to this day. This file keeps the two apart. It reports what is actually documented about the Dönme, then shows how their fluid identity and old secrecy were weaponized, with help from the forged Protocols of the Elders of Zion, into a major current of Turkish antisemitism. Scholars Marc David Baer, Rifat Bali, and Türkay Salim Nefes, and the Moshe Dayan Center, are cited on both the real history and the debunk. The target of this page is the conspiracy theory, never the people it defames.

## The claim
As its promoters state it: that a hidden network of Dönme 'crypto-Jews,' outwardly Muslim but secretly loyal to Judaism, engineered the 1908 Young Turk revolution and the fall of Sultan Abdülhamid II, founded the secular Turkish Republic under leaders who were themselves concealed Jews, and continue to control Turkey's government, economy, and media from behind the scenes.

## Origin and timeline
- 1666: Sabbatai Zevi, a kabbalist from Izmir hailed by many Jews as the messiah, is arrested by Ottoman authorities and converts to Islam rather than face execution. A core of his followers convert with him; they become known as the Dönme (roughly 'converts' or 'turncoats'), while calling themselves 'the believers.' They settle largely in Salonica.
- 17th–19th centuries: The Dönme live as a distinct, endogamous community, outwardly Muslim and privately maintaining Sabbatean traditions, splitting into sub-groups. As historian Marc David Baer documents, by the late 19th century they were prominent in Salonica's commerce, journalism, and modern schools, helping drive the city's modernization.
- 1908–1909: The Young Turk revolution, led by the Committee of Union and Progress that had organized in Salonica, forces the restoration of the constitution; Sultan Abdülhamid II is deposed in 1909. Because the movement arose in a city with large Jewish and Dönme populations, opponents recast a broad Ottoman constitutional movement as a secret 'Jewish-Masonic' plot.
- 1910–1911: British diplomats in Istanbul, including Ambassador Gerard Lowther, circulate dispatches alleging that Jews, Freemasons, and Dönme secretly directed the Committee of Union and Progress. Historians treat these reports as an early diplomatic vector that lent the conspiracy an air of authority it never earned.
- 1923–1924: In the Greece-Turkey population exchange the Dönme, counted as Muslims, are moved from Salonica to Turkey, mostly to Istanbul. In 1924 a community member, Karakaşzade Rüştü, publicly airs the group's separate identity, which suspicious outsiders seize on as proof of hidden loyalties.
- Mid-20th century: The forged Protocols of the Elders of Zion circulates in Turkish translation, and antisemitic writers such as Cevat Rifat Atilhan fuse its imagery of a global Jewish cabal with claims about the Dönme, hardening a local conspiracy tradition that treats secularism itself as a crypto-Jewish scheme.
- 2004: Soner Yalçın, a journalist at the mainstream daily Hürriyet, publishes 'Efendi: The Great Secret of the White Turks,' arguing that a Dönme-descended elite has covertly governed Turkey. It becomes a runaway bestseller, reported to have sold on the order of two hundred thousand copies, and triggers a wave of imitation 'crypto-Jew' exposé books.
- 2000s–2020s: The trope stays in wide circulation, with best-selling books and pro-government commentators variously 'accusing' national founders and living politicians, including Atatürk and, at points, Recep Tayyip Erdoğan, of secret Jewish or Dönme origin. Scholars document it as a persistent, mainstream-adjacent strand of Turkish antisemitism.

## The evidence, claim by claim
- Claim: The Dönme are a real community, so the conspiracy is just describing something that exists.
  Evidence: The community is real, and this file does not dispute it. The Dönme genuinely descend from Sabbatai Zevi's followers who converted to Islam in 1666, genuinely lived as an endogamous group in Salonica, and genuinely kept some private traditions. But describing a small historical religious minority is one thing; claiming that its hidden descendants secretly run a nation of tens of millions is another entirely. The conspiracy smuggles a vast, unevidenced power claim in behind a modest, true historical one. Existence is not control.
- Claim: The 1908 Young Turk revolution was secretly a Dönme and Jewish plot.
  Evidence: The Committee of Union and Progress was a broad Ottoman reform movement of officers, officials, and intellectuals of many backgrounds, not a crypto-Jewish front. It organized in Salonica because that cosmopolitan port was the empire's most modern city, which is also why the smear could latch onto it. The 'Jewish-Masonic' framing traces not to evidence of Dönme direction but to anti-CUP propaganda and to British diplomatic dispatches around 1910; later it was reinforced by the Protocols of the Elders of Zion. Some individuals of Dönme background took part in the era's politics, as did people of every Ottoman community; that is participation in public life, not a hidden hand steering the state.
- Claim: Atatürk and the Republic's founders were secret Jews, which is why Turkey became secular.
  Evidence: There is no credible evidence that Mustafa Kemal Atatürk or the Republic's founders were concealed Jews or Dönme, and the claim's real work is the antisemitic premise beneath it: that a leader's supposed hidden Jewish ancestry would explain and delegitimize a policy someone dislikes. Turkish secularism was a documented political program with its own history and debates; recasting it as a covert Jewish scheme is a way to treat legitimate national history as the product of an alien conspiracy. Ancestry, real or invented, is not an argument, and 'a founder was secretly a Jew' is a slur dressed as an explanation.
- Claim: Bestselling books like 'Efendi' show that serious researchers back the crypto-Jew thesis.
  Evidence: Sales are not an argument. Soner Yalçın's 2004 'Efendi' sold enormously, but scholars who examined it, including Rifat Bali, describe this genre as antisemitic pseudoscience: guilt-by-genealogy, selective 'exposure' of people's ancestry, and recycled Protocols motifs, not documented proof of any governing cabal. A book can top the charts because it flatters an existing suspicion, and Türkay Salim Nefes's research shows exactly that function, with the conspiracy expressing political insecurities rather than reporting a discovered plot. Popularity measures a market, not a fact.
- Claim: The Dönme really were secretive, so suspicion of hidden loyalties is reasonable.
  Evidence: A persecuted minority keeping its rituals private is a survival strategy, not the mark of a plot to run a country. Nefes has specifically analyzed how the community's secrecy is used as the engine of the conspiracy: because the group is discreet, any claim about it can be asserted and none disproven, which makes the theory feel deep while remaining unfalsifiable. The leap from 'this community was private about its religion' to 'this community covertly controls the state and press' is not supported by any document, budget, membership roll, or actor. Secrecy about worship is not a chain of command.
- Claim: Turkey has almost no Jews, so this cannot really be antisemitism.
  Evidence: It is antisemitism precisely of the kind that flourishes without a large Jewish presence. Turkey's Jewish community has dwindled to the low tens of thousands, yet the crypto-Jew conspiracy remains widespread, and that is what scholars stress: the fantasy of hidden Jewish control does not require actual Jews, only a scapegoat. The Moshe Dayan Center and researchers like Bali and Nefes document the real harm, an atmosphere of suspicion, periodic hostility, and pressure on a tiny minority, produced by a smear aimed less at Jews who are present than at a phantom in the theorists' imagination.

## Why people believe it
- It begins with a true history. The Dönme really existed, really followed Sabbatai Zevi into conversion, and really kept to themselves, so the conspiracy can pose as scholarship, and a reader who checks the first claim finds it holds before the false leap is made.
- Secrecy invites projection. Because the community was genuinely private about its religion, almost anything can be asserted about it and little can be disproven, which, as Türkay Salim Nefes shows, is what lets the theory feel like hidden knowledge rather than guesswork.
- It answers political anxiety with a villain. Turkey's 'Sevres syndrome,' the fear of secret plots to subvert the nation, gives the story a ready-made shape; a concealed internal enemy is more satisfying than the tangle of real history.
- It arrived pre-loaded with the Protocols. The forged Protocols of the Elders of Zion supplied a template of a hidden Jewish cabal running finance, media, and government, and the Dönme claim simply pours a local name into that older mold.
- It has been amplified from above. Bestsellers and, at times, pro-government commentary have given the trope reach and a veneer of respectability that a fringe pamphlet could never achieve, making a conspiracy feel like common knowledge.

## Open questions
- What remains genuinely open is historical and narrow, not the conspiracy: scholars still study how large the Dönme community was, how its sub-groups differed, and how far individual members participated in late-Ottoman commerce, journalism, and politics. None of that scholarly detail supports the claim of a hidden hand controlling the state.
- How much specific individuals of Dönme background contributed to particular institutions is a normal question of social history, the kind asked about every Ottoman community. Answering it honestly means counting participation, not positing a secret directorate, and the evidence never crosses from the first into the second.
- Why the trope persists in a country with almost no Jews is a question about propaganda and politics, not ancestry. It survives because it is useful to several camps at once and because the community's old secrecy keeps the story unfalsifiable, which is why debunks that cite only genealogy tend to miss its function.
