The Mandate for Palestine was a League of Nations mandate for British administration of the territories of Palestine and Transjordan, both of which had been conceded by the Ottoman Empire following the end of World War I in 1918. The mandate was assigned to Britain by the San Remo conference in April 1920, after France's concession in the 1918 Clemenceau–Lloyd George Agreement of the previously agreed "international administration" of Palestine under the Sykes–Picot Agreement. Transjordan was added to the mandate after the Arab Kingdom in Damascus was toppled by the French in the Franco-Syrian War. Civil administration began in Palestine and Transjordan in July 1920 and April 1921, respectively, and the mandate was in force from 29 September 1923 to 15 May 1948 and to 25 May 1946 respectively.

12 March 1921 British memorandum explaining the situation of Transjordan: "His Majesty's Government have been entrusted with the Mandate for 'Palestine'. If they wish to assert their claim to Trans-Jordan and to avoid raising with other Powers the legal status of that area, they can only do so by proceeding upon the assumption that Trans-Jordan forms part of the area covered by the Palestine Mandate. In default of this assumption Trans-Jordan would be left, under article 132 of the Treaty of Sèvres, to the disposal of the principal Allied Powers."
25 March 1921 proposal, approved a week later, to include Transjordan via Article 25: "On the assumption that ... provision is made in some way in final political arrangements as regards Trans-Jordania for its inclusion within the boundaries of Palestine as eventually fixed, but under a form of administration different from that of Palestine, however undesirable it may be for His Majesty's Government themselves to propose alterations of the mandates at this stage, they were inclined to view that when the "A" mandates come to be considered by the Council of the League it would be wise in this case to propose to that body the insertion ... after article 24 of the Palestine mandate ..."
League of Nations mandate
A League of Nations mandate represented a legal status under international law for specific territories following World War I, involving the transfer of control from one nation to another. These mandates served as legal documents establishing the internationally agreed terms for administering the territory on behalf of the League of Nations. Combining elements of both a treaty and a constitution, these mandates contained minority rights clauses that provided for the rights of petition and adjudication by the Permanent Court of International Justice.
