Secularism in Turkey in the context of "Secular state"

Turkey, officially the Republic of Türkiye, is a country mainly located in Anatolia in West Asia, with a relatively small part called East Thrace in Southeast Europe. It borders the Black Sea to the north; Georgia, Armenia, Azerbaijan, and Iran to the east; Iraq, Syria, and the Mediterranean Sea to the south; and the Aegean Sea, Greece, and Bulgaria to the west. Turkey is home to over 85 million people; most are ethnic Turks, while Kurds are the largest ethnic minority. Officially a secular state, Turkey has a Muslim-majority population. Ankara is Turkey's capital and second-largest city. Istanbul is its largest city and economic center. Other major cities include İzmir, Bursa, and Antalya.

First inhabited by modern humans during the Late Paleolithic, present-day Turkey was home to various ancient peoples. The Hattians were assimilated by the Hittites and other Anatolian peoples. Classical Anatolia transitioned into cultural Hellenization after Alexander the Great's conquests, and later Romanization during the Roman and Byzantine eras. The Seljuk Turks began migrating into Anatolia in the 11th century, starting the Turkification process. The Seljuk Sultanate of Rum ruled Anatolia until the Mongol invasion in 1243, when it disintegrated into Turkish principalities. Beginning in 1299, the Ottomans united the principalities and expanded. Mehmed II conquered Constantinople (modern-day Istanbul) in 1453. During the reigns of Selim I and Suleiman the Magnificent, the Ottoman Empire became a global power. From 1789 onwards, the empire saw major changes, reforms, centralization, and rising nationalism while its territory declined.

Kemalism (Turkish: Kemalizm, also archaically Kamâlizm) or Atatürkism (Atatürkçülük) is a political ideology based on the ideas of Mustafa Kemal Atatürk, the founder and first president of the Republic of Türkiye. Its symbol is the Six Arrows (Altı Ok).

Atatürk's Turkey was defined by sweeping political, social, cultural, and religious reforms designed to separate the Republican state from its Ottoman predecessor and embrace a Western lifestyle, including the establishment of secularism/laicism, state support of the sciences, gender equality, economic statism and more. Most of those policies were first introduced to and implemented in Turkey during Atatürk's presidency through his reforms.

Atatürk's reforms (Turkish: Atatürk İnkılapları or Atatürk Devrimleri), also referred to as the Turkish Revolution (Turkish: Türk Devrimi), were a series of political, legal, religious, cultural, social, and economic policy changes, designed to transform the new Republic of Turkey into a secular, modern nation-state, implemented under the leadership of Mustafa Kemal Atatürk in accordance with the Kemalist framework. The principal political entity, the Republican People's Party (CHP), ruled Turkey as a one-party state from 1923 to 1945, with several exceptions of attempts for a multi-party democracy.

Following Atatürk's death in 1938, his successor İsmet İnönü took over the leadership and integrated further Kemalist reforms. İnönü's work was, however, stranded by World War II. The CHP eventually lost the elections to the Democratic Party in 1950, putting an end to the Turkish Revolution.

Mustafa Kemal Atatürk (c. 1881 – 10 November 1938) was a Turkish field marshal and statesman who was the founder of the Republic of Turkey, serving as its first president from 1923 until his death in 1938. He undertook sweeping reforms, which modernized Turkey into a secular, industrializing nation. Ideologically a secularist and nationalist, his policies and socio-political theories became known as Kemalism.

Born in Salonica in the Ottoman Empire, his early military career saw him involved in the Italo-Turkish and Balkan Wars. As a member of the Committee of Union and Progress and the Young Turks, he played an important part in political events of the late Ottoman Empire, such as the Young Turk Revolution and the 31 March Incident. He rose to prominence with his role in the Defence of Gallipoli during World War I. Following the defeat of the empire after the war, he led the Turkish National Movement, which resisted the empire's partition among the victorious Allied powers. Establishing the provisional "Ankara government", he defeated the forces sent by the Allies, thus emerging victorious from the Turkish War of Independence. During and after the war, the ethnic cleansing of Armenians and Greeks from Anatolia outside of Istanbul, including the Kars region invaded by the Kemalist armies, was largely completed via large-scale massacres, flight, expulsions, and the population exchange between Greece and Turkey. His government subsequently proceeded to abolish the Ottoman sultanate in 1922 and proclaimed the Republic of Turkey in its place in 1923.

The Republican People's Party (Turkish: Cumhuriyet Halk Partisi [dʒumhuːɾiˈjet haɫk 'paɾtisi] , CHP [dʒeːheːpeˑ]) is a Kemalist and social democratic political party in Turkey. It is the oldest political party in Turkey, founded by Mustafa Kemal Atatürk, the first president and founder of the modern Republic of Türkiye. The party is also cited as the founding party of modern Turkey. Its logo consists of the Six Arrows, which represent the foundational principles of Kemalism: republicanism, reformism, laicism, populism, nationalism, and statism. It is currently the second largest party in Grand National Assembly with 139 MPs, behind the ruling conservative Justice and Development Party (AKP).

The political party has its origins in the various resistance groups founded during the Turkish War of Independence, with most members being previously associated with the Committee of Union and Progress. Under the leadership of Mustafa Kemal Atatürk, they united in the 1919 Sivas Congress. In 1923, the "People's Party", soon adding the word "Republican" to its name, declared itself to be a political organisation and announced the establishment of the Turkish Republic, with Atatürk as its first president. As Turkey moved into its authoritarian one-party period, the CHP was the apparatus of implementing far reaching political, cultural, social, and economic reforms in the country.

Religion in Turkey consists of various religious beliefs. While Turkey is officially a secular state, numerous surveys all show that Islam is the country's most common religion. According to the state, 99.8% of the population is initially registered as Muslim. The remaining 0.2% are Christians and adherents of other officially recognised religions such as Judaism. However, because the government registers everyone as Muslim at birth by default, the official statistics can be misleading. There are many people who follow other religions or do not adhere to any religion, yet they are officially classified as 'Muslim' in official records unless they make a contrary claim. These records can be changed or even blanked out on the request of the citizen using a valid electronic signature to sign the electronic application. According to a 2025 report from Pew Research Center, 95% of Turkey self-identified as Muslim. A significant percentage of those are non-observing Cultural Muslims.

Turkey has officially been a secular country since its 1924 constitution was amended in 1928. This was later strengthened and entrenched with the wider appliance of laicism by founder Atatürk during the mid-1930s, as part of the Republican reforms. Strict regulations on religion, including a ban on Islamic attire, were imposed. The rights of Armenian Apostolic, Greek Orthodox, and Jewish citizens were recognized under the Treaty of Lausanne.

Mustafa Kemal Atatürk (c. 1881 – 10 November 1938) was a Turkish field marshal and statesman who was the founder of the Republic of Turkey —after the fall of its predecessor, the Ottoman Empire— and served as its first president from 1923 until his death in 1938. He led sweeping reforms, which modernized Turkey into a secular, industrializing nation. Ideologically a secularist and nationalist, his policies and socio-political theories became known as Kemalism. Atatürk's personality cult and the Kemalist historiography developed around it have had significant and ongoing influences on Turkey's political culture and historical narrative.
