The Presidency of the Republic of Türkiye is the supreme executive institution and head of state of Türkiye, representing the unity of the Turkish nation. Following constitutional reforms implemented in 2018, the office transitioned from a largely parliamentary, ceremonial role into an executive presidency combining the authorities of head of state and head of government. Established on October 29, 1923, with the proclamation of the republic, its inaugural president was modern Türkiye's founding leader, Mustafa Kemal Atatürk.
