How did the world war 1 affect Turkish leaders?

World War I significantly impacted Turkish leaders by leading to the collapse of the Ottoman Empire, which had been the dominant power in the region for centuries. The war's defeat prompted a national awakening, resulting in the rise of Mustafa Kemal Atatürk and the establishment of the Republic of Turkey in 1923. This period marked a shift towards modernization and secularization as Turkish leaders sought to redefine national identity and governance in the aftermath of the empire's disintegration. Ultimately, the war's consequences catalyzed profound political, social, and cultural changes in Turkey.
