1918 Anglo-French Modus Vivendi

The 1918 Anglo–French Modus Vivendi was a modus vivendi agreement signed on 30 September 1918 regarding the creation of the Occupied Enemy Territory Administration in the area of modern-day Syria, Jordan, Israel, Lebanon and Palestine. The agreement was first negotiated on 19 September 1918, and was built on the foundation of the previous Anglo-French agreement relating to the area, known as the 1916 Sykes-Picot agreement.

While the agreement was ostensibly focused on the French goal to take responsibility over their allotted areas of responsibility, now under Allenby’s military command, the British used the agreement to begin the revision of the Sykes-Picot allocations.

In practice, the agreement resulted in the creation of the three OETA territories: South (Palestine) with a British-led administration, West (the north Mediterranean coast including Lebanon), with a French-led administration, and East (inland Syria including Transjordan), with an Arab-led administration.

2. At the request of the Commander-in-chief, and subject to his supreme authority, the Chief Political Adviser will be charged by the Commander- in-Chief with the establishment of such provisional administration in the towns of the Syrian littoral situated in the blue area, and in the blue area in general.

3. Subject to the approval of the Commander- in-Chief, the Chief Political Adviser will provide […] Such European advisory staff and assistants as the Arab government or governments set up in Area ‘A’ may require under clause 1 of the Anglo–French Agreement of 1916 […] Such personnel as may be necessary for civil duties in the littoral towns or other parts of the blue area.
