The Damascus Protocol was a document given to Faisal bin Hussein on 23 May 1915 by the Arab secret societies al-Fatat and al-'Ahd[1] on his second visit to Damascus during a mission to consult Turkish officials in Constantinople.
The secret societies declared they would support Faisal's father Hussein bin Ali's revolt against the Ottoman Empire, if the demands in the protocol were submitted to the British. These demands, defining the territory of an independent Arab state to be established in the Middle East that would encompass all of the lands of Ottoman Western Asia south of the 37th parallel north,[2] became the basis of the Arab understanding of the Hussein–McMahon Correspondence.
