The British administered Mandatory Palestine after World War I, having promised to establish a homeland for the Jewish people. The modern definition of the region follows the boundaries of that entity, which were fixed in the North and East in 1920–23 by the British Mandate for Palestine (including the Transjordan memorandum) and the Paulet–Newcombe Agreement, and on the South by following the 1906 Turco-Egyptian boundary agreement.
