The pan-Arab colors are black, white, green and red. Individually, each of the four pan-Arab colors were intended to represent a certain aspect of the Arab people and their history. [1]
The four colors derive their potency from a verse by 14th century Arab poet Safi al-Din al-Hilli: "White are our acts, black our battles, green our fields, and red our swords." [3] . The black is the Black Standard, which was used by the Rashidun and Abbasid Caliphate, while white was the dynastic color of the Umayyad Caliphate. [4] Green is a color associated with Islam, the primary religion of Arabs. [5] [6] Green is also identified as the color of the Fatimid Caliphate by some modern sources, [4] [7] despite their dynastic color having been white. [8] [9] [10] Finally, red was used as the Hashemite dynastic color.
Pan-Arab colors, used individually in the past, were first combined in 1916 in the flag of the Arab Revolt or Flag of Hejaz. [11] Many current flags are based on Arab Revolt colors, such as the flags of Jordan, Kuwait, Palestine, the Sahrawi Arab Democratic Republic, and the United Arab Emirates. [12]
In the 1950s, a subset of the Pan-Arab colors, the Arab Liberation colors, came to prominence. These consist of a tricolor of red, white and black bands, with green given less prominence or not included. The Arab Liberation tricolor or the Arab Liberation Flag was mainly inspired by the Egyptian Revolution of 1952 and Egypt's official flag under president Mohamed Naguib, [13] which became the basis of the current flags of Egypt, Iraq, Sudan,and Yemen (and formerly in the flags of Syria, the states of North Yemen and South Yemen), and in the short-lived Arab unions of the United Arab Republic and the Federation of Arab Republics. [12]
The Ismaili Shi'ite counter-caliphate founded by the Fatimids took white as its dynastic color, creating a visual contrast to the Abbasid enemy.
...white was also the color associated with the Fatimid caliphs, the opponents of the Abbasids.
...wore white (the Fatimid color) while delivering the sermon (khuṭba) in the name of the Fatimid caliph.
The designs of these flags were later modified, but the four pan-Arab colors were retained and were adopted by Transjordan (1921), Palestine (1922), Kuwait (1961), the United Arab Emirates (1971), Western Sahara (1976) and Somaliland (1996).
