2023 marks the centenary of the Treaty of Lausanne, which ended the state of war between Turkey and the western allies, in particular Greece, and reordered the Near East, settling frontiers and providing for the protection of minorities. This essay reviews the historiography of the period 1915-23 through Greek and British sources in printed books and papers, covering the Greek irredentist claim to western Asia Minor, the Paris peace conference, the occupation of Smyrna, the Greek war against Mustapha Kemal's Turkish nationalists, the collapse of the Greek army, the Lausanne treaty, and the convention on the exchange of Greek and Turkish populations agreed at Lausanne in 1923.
