The nascent Hashemite Kingdom over Greater Syria was forced to surrender to French troops on 24 July 1920 during the Battle of Maysalun;[10] the French occupied only the northern part of the Syrian Kingdom, leaving Transjordan in a period of interregnum. Arab aspirations failed to gain international recognition, due mainly to the secret 1916 Sykes–Picot Agreement, which divided the region into French and British spheres of influence, and the 1917 Balfour Declaration, which promised Palestine to Jews.[11] This was seen by the Hashemites and the Arabs as a betrayal of their previous agreements with the British,[12] including the 1915 McMahon–Hussein Correspondence, in which the British stated their willingness to recognize the independence of a unified Arab state stretching from Aleppo to Aden under the rule of the Hashemites.[13]:55
