During the peace conference following World War I, the Emir Feisal, son of Hussein, Sherif of Mecca, signed an agreement with Dr Chaim Weizmann (who became later the first president of Israel) supporting the rights of the Jews in Palestine. However, in a handwritten note, the agreement was made contingent by Feisal upon fulfillment by the British of their promises to Feisal. Namely, the "Arab State" that would be formed, would include Syria.
