The deal was reached in secret, in part because it was a betrayal of promises the British government had already made to Hussein bin Ali, the Sharif of Mecca. During the war, in an effort to foment an Arab rebellion against the Ottomans, the British sought Hussein`s support by agreeing to support the creation of an independent Arab state with some reservations. In the so-called McMahon-Hussein correspondence, Britain laid out the terms: it wanted to enforce rights in Baghdad and Basra and set aside parts of present-day Syria that it said were not entirely Arab. The Arabs duly revolted against the Ottomans, with the help of british military officer T.E. Lawrence. But after the war, the British claimed that correspondence was not a formal treaty, although Hussein and his family insisted on it. In any case, the promises made to Hussein were in irreconcilable conflict with the Sykes-Picot agreement. The Frenchman elected Picot to the post of French High Commissioner for the soon-to-be-occupied territory of Syria and Palestine. The British appointed Sykes chief political officer of the Egyptian Expeditionary Force. On April 3, 1917, Sykes met with Lloyd George, Curzon, and Hankey to obtain his instructions in this regard, namely to keep the French next door and at the same time to lobby for a British Palestine. First Sykes in early May, then Picot and Sykes visited hejayz together later in May to discuss the deal with Faisal and Hussein. :166 Hussein was persuaded to accept a formula that precalculated that the French in Syria would follow the same policy as the British in Baghdad; as Hussein believed that Baghdad would be part of the Arab state, this had finally satisfied him.
Subsequent reports from participants expressed doubts about the exact nature of the discussions and the extent to which Hussein had actually been informed of Sykes-Picot`s conditions.  On the occasion of the centenary of Sykes-Picot in 2016, the media and universities were very interested in the long-term effects of the agreement. The agreement is often referred to as an „artificial“ border in the Middle East, „regardless of ethnic or sectarian characteristics, [which] has led to endless conflicts.“  The extent to which Sykes-Picot actually shaped the borders of the modern Middle East is controversial.   Dead and buried or undead and haunting the Middle East today, the Sykes-Picot agreement has echoes that still resonate. Despite the controversy when the text was revealed, the British and French were not deterred from signing another secret agreement in 1956, five years after Georges-Picot`s death. .
