The struggle for Turkish independence started on May 15, 1919, when the first bullet against the occupant Greek forces was fired by Hasan Tahsin, a Turkish journalist who was killed shortly after his action.
Turkish army, under the leadership of Atatürk, won incredible battles against the occupant forces-including the first and second Battles of İnönü, Sakarya, and the Great Offensive-until 1923 when the Lausanne Treaty was signed on July 24.
The incredible achievements on the battlefield led to Turkish independence, and the Republic of Türkiye was founded on Oct. 29, 1923.
Atatürk became the first president of the republic and served in that capacity until Nov. 10, 1938, when he passed away in Istanbul at the age of 57 due to cirrhosis.
