After World War I, Alanya was nominally partitioned in the 1917 Agreement of St.-Jean-de-Maurienne to Italy, before returning to the Turkish Republic in 1923 under the Treaty of Lausanne. Like others in this region, the city suffered heavily following the war and the population exchanges that heralded the Turkish Republic, when many of the city's Christians resettled in Nea Ionia, outside Athens. The Ottoman census of 1893 listed the number of Greeks in the city at out of a total population of . Tourism in the region started among Turks who came to Alanya in the 1960s for the alleged healing properties of Damlataş Cave, and later the access provided by Antalya Airport in 1998 allowed the town to grow into an international resort. Strong population growth through the 1990s was a result of immigration to the city, and has driven a rapid modernization of the infrastructure.
