Passage: The First World War was a disaster for the Ottoman Empire. British and allied forces had conquered Baghdad, Damascus, and Jerusalem during the war and most of the Ottoman Empire was divided amongst the European allies. At the San Remo conference of April 1920, the French were granted a mandate over Syria and the British were granted one over Palestine and Mesopotamia. On 10 August 1920, Mehmed's representatives signed the Treaty of Sèvres, which recognised the mandates and recognised Hejaz as an independent state.
