During World War I the great powers made a number of decisions concerning the future of Palestine without much regard to the wishes of the indigenous inhabitants. Palestinian Arabs, however, believed that Great Britain had promised them independence in the Hussein-McMahon correspondence, an exchange of letters from July 1915 to March 1916 between Sir Henry McMahon, British high commissioner in Egypt, and Hussein ibn Ali, then emir of Mecca, in which the British made certain commitments to the Arabs in return for their support against the Ottomans during the war. Yet by May 1916 Great Britain, France, and Russia had reached an agreement (the Sykes-Picot Agreement) according to which, inter alia, the bulk of Palestine was to be internationalized. Further complicating the situation, in November 1917 Arthur Balfour, the British secretary of state for foreign affairs, addressed a letter to Lord Lionel Walter Rothschild (the Balfour Declaration) expressing sympathy for the establishment in Palestine of a national home for the Jewish people on the understanding that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine. This declaration did not come about through an act of generosity or stirrings of conscience over the bitter fate of the Jewish people. It was meant, in part, to prompt American Jews to exercise their influence in moving the United States to support British postwar policies as we'll as to encourage Russian Jews to keep their nation fighting.
Palestine was hard-hit by the war. In addition to the destruction caused by the fighting, the population was devastated by famine, epidemics, and Ottoman punitive measures against Arab nationalists. Major battles took place at Gaza before Jerusalem was captured by British and Allied forces under the command of General Sir Edmund (later 1st Viscount) Allenby in December 1917. The remaining area was occupied by the British by October 1918.
At the war's end, the future of Palestine was problematic. Great Britain, which had set up a military administration in Palestine after capturing Jerusalem, was faced with the problem of having to secure international sanction for the continued occupation of the country in a manner consistent with its ambiguous, seemingly conflicting wartime commitments. On March 20, 1920, delegates from Palestine attended a general Syrian congress at Damascus, which passed a resolution rejecting the Balfour Declaration and elected Faisal I son of Hussein ibn Ali, who ruled the Hejaz king of a united Syria (including Palestine). This resolution echoed one passed earlier in Jerusalem, in February 1919, by the first Palestinian Arab conference of Muslim-Christian associations, which had been founded by leading Palestinian Arab notables to oppose Zionist activities. In April 1920, however, at a peace conference held in San Remo, Italy, the Allies divided the former territories of the defeated Ottoman Empire. Of the Ottoman provinces in the Syrian region, the northern portion (Syria and Lebanon) was mandated to France, and the southern portion (Palestine) was mandated to Great Britain. By July 1920 the French had forced Faisal to give up his newly founded kingdom of Syria. The hope of founding an Arab Palestine within a federated Syrian state collapsed and with it any prospect of independence. Palestinian Arabs spoke of 1920 asʿām al-nakbah, the year of the catastrophe.
Uncertainty over the disposition of Palestine affected all its inhabitants and increased political tensions. In April 1920 anti-Zionist riots broke out in the Jewish quarter of Old Jerusalem, killing several and injuring scores. British authorities attributed the riots to Arab disappointment at not having the promises of independence fulfilled and to fears, played on by some Muslim and Christian leaders, of a massive influx of Jews. Following the confirmation of the mandate at San Remo, the British replaced the military administration with a civilian administration in July 1920, and Sir Herbert (later Viscount) Samuel, a Zionist, was appointed the first high commissioner. The new administration proceeded to implement the Balfour Declaration, announcing in August a quota of 16,500 Jewish immigrants for the first year.
In December 1920, Palestinian Arabs at a congress in Haifa established an executive committee (known as the Arab Executive) to act as the representative of the Arabs. It was never formally recognized by the British and was dissolved in 1934. However, the platform of the Haifa congress, which set out the position that Palestine was an autonomous Arab entity and totally rejected any rights of the Jews to Palestine, remained the basic policy of the Palestinian Arabs until 1948. The arrival of more than 18,000 Jewish immigrants between 1919 and 1921 and land purchases in 1921 by the Jewish National Fund (established in 1901), which led to the eviction of Arab peasants (fellahin), further aroused Arab opposition that was expressed throughout the region through the Christian-Muslim associations. On May 1, 1921, more serious anti-Zionist riots broke out in Jaffa and spread to Petah Tikva and other Jewish communities, in which nearly 100 we're killed. An Arab delegation of notables visited London in August-November 1921, demanding that the Balfour Declaration be repudiated and proposing the creation of a national government with a parliament democratically elected by the countries Muslims, Christians, and Jews. Alarmed by the extent of Arab opposition, the British government issued awhite paperin June 1922 declaring that Great Britain did not contemplate that Palestine as a whole should be converted into a Jewish National Home, but that such a Home should be founded in Palestine. Immigration would not exceed the economic absorptive capacity of the country, and steps would be taken to set up a legislative council. These proposals we're rejected by the Arabs, both because they constituted a large majority of the total mandate population and therefore wished to dominate the instruments of government and rapidly gain independence and because, they argued, the proposals allowed Jewish immigration, which had a political objective, to be regulated by an economiccriterion.
The British mandate of palestine

British mandate of Palestine
In July 1922 the Council of the League of Nations approved the mandate instrument for Palestine, including its preamble incorporating the Balfour Declaration and stressing the Jewish historical connection with Palestine. Article 2 made the mandatory power responsible for placing the country under such political, administrative and economic conditions as will secure the establishment of the Jewish National Home and the development of self-governing institutions. Article 4 allowed for the establishment of a Jewish Agency to advise and cooperate with the Palestine administration in matters affecting the Jewish national home. Article 6 required that the Palestine administration, while ensuring that the rights and position of other sections of the population are not prejudiced, under suitable conditions should facilitate Jewish immigration and close settlement of Jews on the land. Although Transjordan i.e., the lands east of the Jordan River constituted three-fourths of the British mandate of Palestine, it was, despite protests from the Zionists, excluded from the clauses covering the establishment of a Jewish national home. On September 29, 1923, the mandate officially came into force.
