Mustafa Kemal Atatürk (1881 – 10 November 1938) was a Turkish field marshal and statesperson 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, republican 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.
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.
