During its brief existence, the kingdom was led by Faisal, the son of Sharif Hussein bin Ali. Despite its claims to the territory of Greater Syria, Faisal's government controlled a limited area and was dependent on Britain which, along with France, generally opposed the idea of a Greater Syria and refused to recognize the kingdom. Shortly after the Jerusalem riots of early April, the San Remo conference at the end of April 1920, awarded the Palestine mandate to Britain and the authorities decided to refuse permission for the convening of a second Palestinian Arab Congress intended to address the new situation. In a lecture given at the UN, Rashid Khalidi noted that the Palestine reaction to the declaration was delayed by the continuing closure of newspapers for two years and the dismal post-war circumstances of the country. The military administration had decided not to publish the Balfour Declaration for fear of the consequences. After the appointment of Herbert Samuel was known, on 28 April 1920 in Acre, General Bols informed the "representatives of all communities" that the mandate and declaration would be included in the peace treaty with Turkey. The Palin Commission speculated that, in view of all the later "misunderstandings", it might have been wiser to have published the declaration in the first instance and avoid the confusion. It was not until May 1920 that the text of the Balfour Declaration was read out in Nablus by Sir Louis Bols. at Cairo and Jerusalem The Executive Committee of the third Palestine Arab Congress, headed by Musa Kazim al-Husseini, met the new High Commissioner, Herbert Samuel, who refused to give them any official recognition unless they accepted British policy for a Jewish national home. Having been rebuffed in their attempt to have discussions with Churchill in Cairo, on 28 March 1921, the committee instead met Churchill in Jerusalem for that part of the Cairo conference and presented a memorandum detailing their complaints; while he assured the committee that in respect of the second part of the Balfour Declaration,"if one promise stands so does the other", he said that it was a matter of policy and the Arabs could do nothing other than accept it and the consequences, including Jewish immigration. In Cairo, Palestine had been discussed with Emir Abdullah who argued that he should be given control of the entire area of Mandate Palestine responsible to the High Commissioner. Alternatively
