What happened to the Ottoman Turks who controlled the land?

The Ottoman Turks, who controlled vast territories for centuries, faced significant decline after World War I. The empire was dismantled as a result of military defeat and subsequent treaties, leading to the loss of much of its land. In 1923, the Republic of Turkey was established under Mustafa Kemal Atatürk, marking the end of the Ottoman Empire and the emergence of a modern nation-state. Many Ottoman Turks found themselves navigating a new national identity amidst the significant political and social changes that followed.
