What was a major effect of World War 1 on Turkey?

A major effect of World War I on Turkey was the collapse of the Ottoman Empire, which had been a dominant power in the region for centuries. The war led to significant territorial losses and the eventual establishment of the Republic of Turkey in 1923, under the leadership of Mustafa Kemal Atatürk. This transition marked a shift from a multi-ethnic empire to a nation-state, fostering a sense of Turkish nationalism and initiating extensive political, cultural, and social reforms.
