In Turkey, secularism or laicism (or laïcité) was first introduced with the 1928 amendment of the Constitution of 1924, which removed the provision declaring that the "Religion of the State is Islam", and with the later reforms of Turkey's first president Mustafa Kemal Atatürk, which set the administrative and political requirements to create a modern, democratic, secular state, aligned with Kemalism.
Nine years after its introduction, laïcité was explicitly stated in the second article of the then Turkish constitution on February 5, 1937. The current Constitution of 1982 neither recognizes an official religion nor promotes any.
The principles of Turkish secularism, and the separation of state and religion, were historically established in order to modernize the nation. This centralized progressive approach was seen as necessary not only for the operation of the Turkish government but also to avoid a cultural life dominated by superstition, dogma, and ignorance.
Turkey's concept of laiklik ("laicism") calls for the separation of state and religion, but also describes the state's stance as one of "active neutrality", which involves state control and legal regulation of religion. Turkey's actions related with religion are carefully analyzed and evaluated through the Presidency of Religious Affairs (Diyanet İşleri Başkanlığı or simply Diyanet). The duties of the Presidency of Religious Affairs are "to execute the works concerning the beliefs, worship, and ethics of Islam, enlighten the public about their religion, and administer the sacred worshipping places".
The history of secularism in Turkey extends to the Tanzimat reforms of Ottoman Empire. The second peak in secularism occurred during the Second Constitutional Era. The current form was achieved by Atatürk's Reforms.
The establishing structure (Ruling institution of the Ottoman Empire) of the Ottoman Empire (13th century) was an Islamic state in which the head of the Ottoman state was the Sultan. The social system was organized around millet.
