Mustafa Kemal

Mustafa Kemal (later Atatürk) was the commander of the Ottoman 19th Division at Gallipoli on 25 April 1915. He later led the Ottoman counter-attacks to recapture Chunuk Bair during the Sari Bair offensive. After the armistice in 1918, he became leader of Turkish nationalist forces in the post-war conflicts that resulted in the establishment of the Republic of Türkiye, of which he became the first president in 1923.
