At the Cairo Conference of March 1921, the British set the parameters for Iraqi political life that were to continue until the 1958 revolution; they chose a Hashemite, Faisal ibn Husayn, son of Sherif Hussein ibn Ali former Sharif of Mecca as Iraq's first King; they established an Iraqi army (but kept Iraq Levies under direct British command); and they proposed a new treaty. To confirm Faisal as Iraq's first monarch, a one-question plebiscite was carefully arranged that had a return of 96 percent in his favor. The British saw in Faisal a leader who possessed sufficient nationalist and Islamic credentials to have broad appeal, but who also was vulnerable enough to remain dependent on their support. Faisal traced his descent from the family of the Prophet Muhammad. His ancestors held political authority in the holy cities of Mecca and Medina since the 10th century. The British believed these credentials would satisfy traditional Arab standards of political legitimacy; moreover, the British thought Faisal would be accepted by the growing Iraqi nationalist movement because of his role in the 1916 Arab Revolt against the Turks, his achievements as a leader of the Iraq emancipation movement, and his general leadership qualities. Faisal was instated as the Monarch of Iraq after the Naquib of Baghdad was disqualified as being too old (80 yrs) and Sayid Talib (a prominent Iraqi from the province of Basra) was deported on trumped up charges by the British. The voting was far from a reflection of the true feelings of the Iraqi people. Nevertheless, Faisal was considered the most effective choice for the throne by the British government.
