Curzon worked on several Middle Eastern problems. He designed the Treaty of Sèvres (August 10, 1920) between the victorious Allies and Ottoman Turkey. The treaty abolished the Ottoman Empire and obliged Turkey to renounce all rights over Arab Asia and North Africa. However a new government in Turkey under Kemal Atatürk rejected the treaty. The Greeks invaded Turkey. Curzon tried and failed to induce the Greeks to accept a compromise on the status of Smyrna and failed to force the Turks to renounce their nationalist program. Lloyd George tried to use force at Chanak but lost support and was forced to step down as prime minister. Curzon remained as foreign minister and helped tie down loose ends in the Middle East at the peace conference at Lausanne.
