the island's main urban centres gradually began to warm to the ideas of positivism, freedom and modernization. Spurred on by the rising calls for "enosis", the union with Greece, emanating from Greek Cypriots, an initially hesitant "Turkism" was also starting to appear in certain newspaper articles and to be heard in the political debates of the local intelligentsia of Cyprus. In line with the changes introduced in the Ottoman Empire after 1908, the curricula of Cyprus's Muslim schools, such as the "Idadi", were also altered to incorporate more secular teachings with increasingly Turkish nationalist undertones. Many of these graduates in due course ended up as teachers in the growing number of urban and rural schools that had begun to proliferate across the island by the 1920s. In 1914 the Ottoman Empire joined the First World War against the Allied Forces and Britain annexed the island. Cyprus's Muslim inhabitants were officially asked to choose between adopting either British nationality or retaining their Ottoman subject status; about 4,000–8,500 Muslims decided to leave the island and move to Turkey. Following its defeat in World War I, the Ottoman Empire were faced with the Greco-Turkish War (1919–1922) whereby the Greek incursion into Anatolia aimed at claiming what Greece believed to be historically Greek territory. For the Ottoman Turks of Cyprus, already fearing the aims of enosis-seeking Greek Cypriots, reports of atrocities committed by the Greeks against the Turkish populations in Anatolia, and the Greek Occupation of Smyrna, produced further fears for their own future. Greek forces were routed in 1922 under the leadership of Mustafa Kemal Atatürk who, in 1923, proclaimed the new Republic of Turkey and renounced irredentist claims to former Ottoman territories beyond the Anatolian heartland. Muslims in Cyprus were thus excluded from the nation-building project, though many still heeded Atatürk's call to join in the establishment of the new nation-state, and opted for Turkish citizenship. Between 1881 and 1927 approximately 30,000 Turkish Cypriots emigrated to Turkey. The 1920s was to prove a critical decade in terms of stricter ethno-religious compartments; hence, Muslim Cypriots who remained on the island gradually embraced the ideology of Turkish nationalism due to the impact of the Kemalist Revolution. At its core were the Kemalist values of secularism, modernization and westernization; reforms such as the introduction of the new Turkish alphabet, adoption of western dress and secularization, were adopted voluntarily by Muslim Turkish Cypriots, who had been
