The Sykes-Picot agreement, signed clandestinely in 1916 between France and England and leaked a year later by the communist press, justified the division of the Ottoman territories into several spheres of influence. The agreement included spheres of Russian and Italian influence in Anatolia, but it focused mainly on the division of the Levant and Mesopotamia between the French who would occupy Syria, Lebanon and Alexandria and the British, who were to manage Jordan and Iraq today. Palestine has been left an international zone. This more or less corresponded to the Balfour Declaration of 1917, a document by which the British, Baron Rothschild and the Zionist movement, had promised the creation of a „Jewish homeland“ in Palestine. It was convened following the February conference in London, at which the Allies met to discuss the division of the Ottoman Empire and the negotiation of agreements that would become the Treaty of Sevres. Finally, and perhaps most importantly, the San Remo resolution laid the groundwork for the Palestinian mandate and, perhaps unknowingly, the Arab-Israeli conflict. The agreement entrusted the British Empire with the responsibility of implementing „the creation of a national homeland for the Jewish people“ and ensuring that nothing was done that would „harm the political and civil rights of non-Jewish communities in Palestine or the political rights and status enjoyed by Jews in other countries.“ The document did not specify how the creation of a national home for Jews would be compatible with respect for the rights of indigenous peoples who had not been consulted on the matter and who felt discriminated against by British politics. Although there were examples of coexistence and cooperation, violent incidents increased between Arabs and new Jewish immigrants over the next two decades. The 1947-48 war was not prevented or avoided by British administrators, who were accused by some historians of exploiting disputes to their own advantage. The decisions of the San Remo conference confirmed the award of the mandates of the London conference. The San Remo resolution, adopted on April 25, 1920, contained the Balfour Declaration of 1917. You and Article 22 of the League of Nations were the basic documents on which the British mandate for Palestine was built.
As part of the Balfour Declaration, the British government pledged to advocate the creation of a national homeland for the Jewish people in Palestine, without prejudice to the civil and religious rights of non-Jewish communities in Palestine or the rights and political status enjoyed by Jews in any other country.  Article 22, paragraph 4, of the pact referred to certain categories of the population as „communities that once belonged to the Turkish Empire“ as a „development phase in which their existence can be temporarily recognized as an independent nation“ (the League_of_Nations_mandate-Types_of_mandates Class A mandate) and charged the obligation to „provide administrative advice and support to these territories until they are able to remain alone.“
