The British Mandate for Palestine, also known as the Palestine Mandate, The British Mandate of Palestine and the Mandate for Palestine, was a legal commission for the administration of Palestine, the draft of which was formally confirmed by the Council of the League of Nations on 24 July 1922 and which came into effect on 26 September 1923. The document was based on the principles contained in Article 22 of the draft Covenant of the League of Nations and the San Remo Resolution of 25 April 1920 by the principal Allied and associated powers after the First World War. The mandate formalised British rule in the southern part of Ottoman Syria from 1923–1948. With the League of Nations` consent on 16 September 1922, the UK divided the Mandate territory into two administrative areas, Palestine, under direct British rule, and autonomous Transjordan, under the rule of the Hashemite family from the Kingdom of Hejaz in present-day Saudi Arabia, in accordance with the McMahon Correspondence of 1915. Following the 1922 Transjordan memorandum, the area east of the Jordan river became exempt from the Mandate provisions concerning the Jewish National Home.
