In the Sykes-Picot Agreement, concluded on 19 May 1916, France and Great Britain divided the Arab territories of the former Ottoman Empire into spheres of influence. In its intended area, it was agreed that each country can establish a direct or indirect administration or control, as they wish and as they see fit to agree with the Arab State or with the Arab confederation. Under Sykes-Picot, the Syrian coast and much of present-day Lebanon went to France; Britain would take direct control of central and southern Mesopotamia around the provinces of Baghdad and Basra. Palestine would have an international administration, because other Christian powers, namely Russia, were interested in this region. The rest of the territory in question – a vast territory with syria today, Mosul in northern Iraq and Jordan – would have local Arab leaders under French surveillance to the north and Britons to the south. In addition, Britain and France would retain free passage and trade within the other`s zone of influence. On 15 September, the British distributed a memory aid (which had been the subject of a private debate two days earlier between Lloyd George and Clemenceau ), in which the British withdrew their troops in Palestine and Mesopotamia and handed over Damascus, Homs, Hama and Aleppo to Fayçal`s troops. While accepting the withdrawal, clemenceau continued to insist on the Sykes-Picot agreement as the basis for all discussions.  In April 1920, the San Remo Conference distributed Class A warrants on Syria to France and Iraq and Palestine to Britain. The same conference ratified an oil agreement reached at a London conference on 12 February, based on a slightly different version of the Long Berenger agreement, previously signed on 21 December in London. The agreement was originally used directly as the basis for the 1918 Anglo-French modus vivendi, which provided a framework for the Occupied Enemy Territory Administration in the Levant. More generally, it was to lead indirectly to the subsequent partition of the Ottoman Empire after the Ottoman defeat of 1918. Shortly after the war, French Palestine and Mosul ceded to the British.
Warrants in the Levant and Mesopotamia were awarded at the San Remo conference in April 1920, according to the Sykes-Picot framework; The British mandate for Palestine ran until 1948, the British mandate for Mesopotamia was to be replaced by a similar treaty with compulsory Iraq, and the French mandate for Syria and Lebanon lasted until 1946. The anatolic parts of the agreement were attributed by the Treaty of Sevres of August 1920; But these ambitions were thwarted by the Turkish War of Independence of 1919-23 and the Subsequent Treaty of Lausanne. George Curzon said: The great powers remain committed to the Organic Settlement Agreement, regarding governance and non-interference in the affairs of the Maronite, Orthodox Christian, Druze and Muslim communities with regard to the Beirut Vilayet of June 1861 and September 1864, adding that the rights granted to France in present-day Syria and parts of Turkey under sykes-Picot are incompatible with this agreement.  If we are seen over the years in the broader context of other agreements, declarations and promises to the actors in the region, we see how the agreement is at the root of so many contemporary problems. The French elected Picot as French High Commissioner for the soon-to-be-occupied territory of Syria and Palestine. The British appointed Sykes political chief of the Egyptian Expeditionary Force. On April 3, 1917, Sykes met Lloyd George, Curzon and Hankey to receive his instructions on the matter, namely to keep the French on their side as they pushed towards a British Palestine.
