During the Abbasid Revolution, the Abbasids incorporated the Black Standard based on the early-Islamic eschatological saying that "a people coming from the East with black banners" would herald the arrival of the messianic figure Mahdi.[9] The Umayyad opponents, as well as the Shiite Alids chose the color of white to distinguish themselves from the Abbasids.[7] Abbasids continued to deploy black as their dynastic color. However, their caliphal banner was made of white silk with the Quranic inscriptions. The white color was continually adopted by the Ismaili-Shiite Fatimid Caliphate, and cemented the association of black and white with Sunni and Shia respectively.
