Although historically part of a separate region (known in Roman times as Arabia Petraea), the Negev was added to the proposed area of Mandatory Palestine, of which large parts later became Israel, on 10 July 1922, having been conceded by British representative St John Philby "in Trans-Jordan's name". Despite this, the region remained exclusively Arab until 1946; in response to the British Morrison–Grady Plan which would have allotted the area to an Arab state, the Jewish Agency enacted the 11 points in the Negev plan to begin Jewish settlement in the area. Within a year, the United Nations Partition Plan for Palestine allotted the area to the Jewish State, later Israel.
