East Thrace
On 5 September 1922, Mustafa Kemal Atatürk asserted the Turkish claim to East Thrace. On 15 September, the British cabinet decided that British forces should maintain their position, and issued an ultimatum. On 19 September Britain decided to deny Constantinople and Thrace to the Turkish nationalists, but France, Yugoslavia, Italy, and the British Dominions objected to another war. Raymond Poincaré, the French prime minister, tried to persuade the Turks to respect the neutral zone. The allies asked for a peace conference on 23 September, to which Mustafa Kemal agreed on 29 September, nominating Mudanya as the venue. At the same time, the British cabinet decided to abandon East Thrace to the Turks.
