The Sharifian or Sherifian Solution, () as first put forward by T. E. Lawrence in 1918, was a plan to install three of Sharif Hussein's four sons as heads of state in newly created countries across the Middle East: his second son Abdullah ruling Baghdad and Lower Mesopotamia, his third son Faisal in Syria, and his fourth son Zeid in Upper Mesopotamia. The Sharif himself would not wield any political power in these places, and his first son, Ali would be his successor in Hejaz. Given the need to rein in expenditure and factors outside British control, including France's removing of Faisal from Syria in July 1920, and Abdullah's entry into Transjordan (which had been the southern part of Faisal's Syria) in November 1920, the eventual Sharifian solution was somewhat different, the informal name for a British policy put into effect by Secretary of State for the Colonies Winston Churchill following the 1921 Cairo conference. Faisal and Abdullah would rule Iraq and Transjordan respectively; Zeid did not have a role, and ultimately it proved impossible to make satisfactory arrangements with Hussein and the Kingdom of Hejaz. An underlying idea was that pressure might be applied in one state to secure obedience in another; as it transpired, the inherent assumption of family unity was misconceived. Antonius' The Arab Awakening (1938) later disparaged Lawrence's claim in his Seven Pillars of Wisdom (1926) that Churchill had "made straight all the tangle" and that Britain had fulfilled "our promises in letter and spirit". Abdullah was assassinated in 1951, but his descendants continue to rule Jordan today. The other two reigning branches of the dynasty did not survive; Ali was ousted by Ibn Saud after the British withdrew their support from Hussein in 1924/25, while Faisal's grandson Faisal II and Ali’s son 'Abd al-Ilah were executed in the 1958 Iraqi coup d'état. The Tangle Failure in Syria Faisal was the first of Hussein's sons to gain an official role, in OETA East, a joint Arab-British military administration. The Arab and British armies entered Damascus on 1 October 1918, and on 3 October 1918 Ali Rida al-Rikabi was appointed Military Governor of OETA East. Faisal entered Damascus as on 4 October and appointed Rikabi Chief of the Council of Directors (i.e. prime minister) of Syria. The territory consisted of the Ottoman Damascus Vilayet and the southern part of the Aleppo Vilayet. The area of Ma'an and
