Iraq–Jordan border

[2][3] During the First World War an Arab Revolt, supported by Britain, succeeded in removing the Ottomans from most of the Middle East.

[4] Eventually in 1921 Britain declared a mandate over the region, creating the Emirate of Transjordan, under the semi-autonomous rule of King Abdullah I.

[3] The location of the Eastern border between Transjordan and Iraq was considered strategic with respect to the proposed construction of what became the Kirkuk–Haifa oil pipeline.

[8] This followed a proposal from T. E. Lawrence in January 1922 that Transjordan be extended to include Wadi Sirhan as far south as al-Jauf, in order to protect Britain's route to India and contain Ibn Saud.

[3] Eventually an Iraq–Jordan border consisting of a single straight line was agreed upon by an exchange of notes between British and King Abdullah in July–August 1932.
