This chapter discusses the end of the Ottoman Empire, looking at three case studies which illustrate the pattern of change seen in the transition from the Ottoman Empire to nation-states. Greece, the first Ottoman territory to gain independence (1830), set precedents in establishing government by non-natives, introducing religious and legal institutions based on European models and working single-mindedly to instill national identity in its population. Almost a century later, King Faysal I (r. 1921–1933) of Iraq followed a similar path, albeit under British direction. The Republic of Turkey was founded in 1922 and offered a slight variation on the pattern in that it built on selected legacies from the late Ottoman Empire. It was the only post-Ottoman country founded primarily by internal effort rather than by European intervention, and the national identity it worked to entrench in the population drew upon the political ideas of the Committee of Union and Progress (CUP), which had dominated Ottoman government from 1908 to 1918. Despite that continuity, the republican government pursued the agenda of tearing down Ottoman institutions and rebuilding state and society as national projects. Such nation-building ultimately succeeded, producing its own instabilities; in new post-Ottoman countries such as Greece, Iraq, and Turkey, social and political re-engineering aroused resistance within the population.
