مؤتمر سان ريمو
At the 1920 San Remo conference, the victorious Allied powers (France, UK, USA, etc.) allocated the area to the British Mandate of Palestine (1920–47). The San Remo Resolution adopted on 25 April 1920 incorporated the Balfour Declaration of 1917. It and Article 22 of the Covenant of the League of Nations were the basic documents upon which the British Mandate for Palestine was constructed. The British proclaimed Abdullah emir of Transjordan on 11 April 1921. He declared it an independent Hashemite kingdom on 25 May 1946.
