Flag of the Arab Revolt

[2] Alternatively, the colours' symbolism has been described as follows: white for the Damascene Umayyad Caliphate, green for Ali, red for the Kharijites, and black for Muhammad, showing the "political use of religion" in opposition to the increasingly secularized Turkish rule.

[2] The explanation given in the official note of the ceremony marking the first anniversary of the Revolt, celebrating Hussein's decree on the adoption of the flag, was that black represented the Black Standard of Muhammad (the al-ʿuqāb "eagle"), his companions, and the Abbasid Caliphate, the green represented the Ahl al-Bayt or Prophetic Family, white various Arab rulers, and red the Hashemites.

[3] It has been suggested that the flag was designed by the British diplomat Sir Mark Sykes, in an effort to create a feeling of "Arab-ness" to fuel the revolt.

[5] According to Stanford University historian Joshua Teitelbaum, this claim is made both by Sykes' 1923 biographer and by Hussein ibn Ali al-Hashimi, who in 1918 told Woodrow Wilson that it symbolized Hashemite rule over the Arab world.

[1] According to one version, Sykes, keen to challenge the French flag being flown in French-controlled Arab territories, offered several designs to Hussein, who chose the one that was then used.
