Turkey sits astride the historical boundary between the Byzantine Christian and Ottoman Islamic worlds, and its territory holds sites central to both, including the Hagia Sophia in Istanbul, built as a Christian cathedral, converted to a mosque, secularized as a museum, and reconverted to a mosque in 2020. The population is overwhelmingly Sunni Muslim, with a significant Alevi minority practicing a distinct heterodox tradition, and small, ancient Armenian Christian, Greek Orthodox and Jewish communities remain, though much reduced from their historical size by twentieth century displacement and emigration. Anatolia was also the setting for early Christian church councils and for Sufi orders, most famously the Mevlevi order of whirling dervishes founded around the poet and mystic Rumi in Konya. The country's formally secular constitution and its Muslim majority culture remain in an ongoing tension that shapes religious life and politics.

Facts

Law and State

Establishment Status

Secular State Declared 2

Turkey has been constitutionally laicist since 1924; Sunni Islam is administered through the state Presidency of Religious Affairs (Diyanet), which does not extend equivalent recognition or funding to Alevi cemevi worship houses.

State Funding Mechanism

Turkey funds Sunni Islamic religious life directly through the state budget of the Presidency of Religious Affairs, the Diyanet, which pays every imam's salary as a civil servant and builds and maintains mosques nationwide. Its 2023 budget of 35.91 billion lira, about 1.2 billion dollars, had already been outspent by nine months in, surpassing the nine-month spending of 26 other public institutions including the interior, energy, trade and foreign affairs ministries, and its 2024 budget rose to 91.83 billion lira, about 3.18 billion dollars, a roughly 156 percent increase, of which 77.6 billion lira was earmarked for personnel. Alevi and non-Sunni minority worship receives no comparable state funding. 3

Apostasy or Blasphemy Law

Turkey criminalizes blasphemy through Article 216, paragraph 3 of the Penal Code (Law No. 5237), which punishes a person who openly insults the religious values of a section of the public with six months to one year of imprisonment where the act is capable of disturbing the public peace. The provision names no specific religion, but the Venice Commission finds it applied in practice to protect the state-recognized Sunni religious establishment rather than religion in general. Turkey has no apostasy law; leaving Islam carries no criminal penalty. Article 216(3) is frequently charged alongside Article 299 (insulting the president) against musicians, actors and government critics accused of mocking Islam or state-sanctioned religious symbols, and USCIRF has tracked a rise in such prosecutions since the mid-2010s as politically motivated rather than confined to genuine public-order concerns. 4

Registration or Recognition Regime

Sunni Muslim religious life runs through the Presidency of Religious Affairs (Diyanet), established in 1924, which regulates the country's registered mosques and employs local and provincial imams as civil servants. Non-Muslim minority communities cannot hold property or bring legal claims as a recognized body at all, because the state does not recognize structures such as the Armenian Apostolic Patriarchate, the Ecumenical Patriarchate or the Chief Rabbinate as legal entities; their institutions instead hold property through independently organized foundations known as vakiflar, overseen by the General Directorate for Foundations, which was established the same year as the Diyanet. 2

Ban or Official Watchlist

Turkey does not recognize cemevis, the houses of worship of the Alevi community, as places of worship, and treats Alevism itself as a cultural tradition within Sunni Islam rather than a distinct faith; the government also obstructs the registration of Alevi, Protestant and Jehovah's Witness houses of worship and the residence of their foreign clergy. The US Commission on International Religious Freedom has recommended the State Department place Turkey on its Special Watch List for these violations. 2

Concordat Basisthe subject's own account

Turkey has no concordat with the Holy See. Representation dates to the Apostolic Delegation to Constantinople, established in 1868 under the Ottoman Empire, renamed the Apostolic Delegation to Turkey in 1930 as the republic's secularizing reforms dismantled the Ottoman millet system that had protected Christian minorities, then raised to an Apostolic Internunciature in 1960 and a full Apostolic Nunciature in 1966. Turkey's constitutional secularism runs its own religious affairs through the state Diyanet rather than through any bilateral instrument with Rome, and Catholic bishops still lack straightforward legal recognition under Turkish law. 5

Religion and History in Turkey

Turkey is overwhelmingly Muslim, around 96 to 99 percent by most estimates including Pew Research's Religious Composition of the World, 2010-2020, with a Sunni Hanafi majority and a substantial Alevi minority, a heterodox tradition drawing on Shia, Sufi and Anatolian folk elements, estimated at somewhere between 10 and 20 percent of the population though precise figures are contested since Alevis are not separately counted in official statistics.

Anatolia's religious history predates Islam considerably: it was a heartland of early Christianity, home to seven of the churches addressed in the Book of Revelation and to the Cappadocian Fathers who shaped Christian doctrine in the fourth century, and Constantinople, refounded as Istanbul after the 1453 Ottoman conquest, served as the seat of the Byzantine Orthodox Church for over a thousand years before becoming the center of Ottoman Sunni Islam.

The Hagia Sophia, built as a cathedral under Justinian in 537, converted to a mosque in 1453, secularized as a museum in 1934 under Ataturk's reforms, and reconverted to a mosque in 2020, embodies these successive religious transformations in a single building. Christian and Jewish minorities, protected historically under the Ottoman millet system, have shrunk dramatically since the early twentieth century through the Armenian Genocide, the 1923 population exchange with Greece, and later emigration.

Secularism, Laicism and Religion in the Turkish Republic

The Turkish Republic, founded by Mustafa Kemal Ataturk in 1923 after the Ottoman Empire's collapse, adopted a distinctive form of secularism known as laicism, abolishing the Ottoman caliphate in 1924 and placing all religious affairs under a state body, the Presidency of Religious Affairs or Diyanet, which appoints imams, writes standardized Friday sermons and controls mosque administration to this day, an arrangement that manages Sunni Islam through the state rather than separating the two entirely.

Alevi communities have long objected to the Diyanet's exclusively Sunni character, since their own cemevi worship houses receive no equivalent state funding or legal recognition as places of worship, a grievance repeatedly raised before the European Court of Human Rights. Headscarf bans in public institutions, in place for decades under strict laicist policy, were progressively lifted in the civil service, universities and finally the military between 2013 and 2017 under the Justice and Development Party government, reflecting a broader contested shift some scholars describe as a re-Islamization of public life and others describe as expanded religious freedom for a pious Muslim majority previously restricted by a secularist elite.

Open Questions (1 open question)

What share of Turkey's population identifies as Alevi?

Turkish national censuses do not ask about sectarian or Alevi religious identity, so no official count of the Alevi population exists. Published estimates commonly range from about 10 to 20 percent of the population, a spread wide enough to reflect the absence of a count rather than disagreement over one.

What would resolve this A nationally representative census or independently conducted survey that specifically asks about Alevi self-identification, which the Turkish state census currently does not do.
