Institutional education in general, and religious education in particular, is centralized in Turkey. This approach began with the Unity of Education Law, which was first drafted in 1924 and preserved in subsequent legal reforms and constitutional changes. Due to the secular revolution, previous practices of the Ottoman education system were abandoned. The newer Unity of Education Law was interpreted as totally excluding religious instruction from public schools. The newly established Republic of Turkey aimed to be secular and more western with the rule of Ataturk. In 1923, changes such as the acceptance of the Latin alphabet, which is taught to pupils in the national schools, and the Gregorian calendar took place in the new established country. With the closure of Madrasas, which were provided for the society to have religious knowledge and education, classes of religion were also abolished from the schools. Religious education such as Quran courses or other religious activities had to be controlled by the government and separated from regular education.
