Flag of the Arab Revolt

The flag of the Arab Revolt, also known as the flag of Hejaz, was a flag used by the Arab nationalists during the Arab Revolt against the Ottoman Empire during World War I, and as the first flag of the Kingdom of Hejaz.
History.
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" in order to fuel the revolt. 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 symbolished Hashemite rule over the Arab world. 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.
Although the Arab Revolt was limited in scope and supported by the British, the flag influenced the national flags of a number of emerging Arab states after World War I. Flags inspired by that of the Arab revolt include those of Egypt, Jordan, Palestine, Iraq, Kuwait, Sudan, Syria, the United Arab Emirates, Yemen, Somaliland, the Sahrawi Arab Democratic Republic and Libya.
The horizontal colors stand for the Abbasid (black), Umayyad (white) and Fatimid or Rashidun (green) Caliphates. The red triangle has been described as referring to the Hashemite dynasty, or the ashraf of Mecca. (According to Tim Marshall, white was the Umayyad colour in memory of Mohammed's first military victory, black was the Abbasid colour to mark a new era and to mourn the dead of the Battle of Karbala, and green was the colour of the Prophet's coat and of his followers as they conquered Mecca. Alternatively, the colours' symbolism has been described as follows: white for the Damascene Umayyad period, green for the Caliph Ali, red for the Khawarij movement, and black for the Prophet Mohammed, showing the "political use of religion" in opposition to the increasingly secularized Turkish colonial rule. Similarly, Marshall explains the use of the European tricolor as a sign of the break with the Ottoman past, while the colours are deeply Islamic without using the star and crescent used by the Ottomans. 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 the Prophet (the "al-ʻuqāb", eagle), his companions and the Abbasid empire, the green represented the Prophet's family (Ahl al-Bayt), white various Arab rulers, and red the Hashemites.
The Hashemites were allies of the British in the conflict against the Ottoman Empire. After the war ended, the Hashemites achieved or were granted rule in the Hejaz region of Arabia, Jordan, formally known as the "Hashemite Kingdom of Jordan", briefly in Greater Syria, and Iraq.
Greater Syria was dissolved after only a few months of existence, in 1920. The Hashemites were overthrown in the Hejaz in 1925 by the House of Saud, and in Iraq in 1958 by a coup d'etat, but retained power in Jordan.
A 60 m × 30 m version of the flag currently flies from the Aqaba Flagpole, currently the sixth tallest freestanding flagpole in the world, located in Aqaba, Jordan.
Description.
