Mustafa Kemal was born in 1881 in Salonica (Thessaloniki), then part of the Ottoman Empire. Educated in military schools, he served in Libya, the Balkan Wars, and gained fame defending Gallipoli against Allied landings in 1915. After the Ottoman defeat in World War I, Allied occupation of Anatolia and Greek incursion spurred nationalist resistance.

Kemal organized congresses at Erzurum and Sivas, built a provisional government in Ankara, and won the Turkish War of Independence (1919–1922). The Treaty of Lausanne recognized the new borders of Turkey. He abolished the sultanate, moved the capital to Ankara, and proclaimed the republic in 1923, taking the surname Atatürk—'Father of the Turks.'

As president until his death in 1938, he imposed Latin script, secular law, women's voting rights, and Western dress reforms while maintaining strong state control. Atatürk's legacy remains central to Turkish national identity, honored in law while debated by critics of his authoritarian methods.
