'alam al-mansûr

'banner [of the] victorious') is a form of flag that was used as the emblem of the Almohad, Marinid, and Saadi dynasties of Morocco consisting of a white banner with an Islamic symbol written on it which were followed in parades by several banners of different colors, most of them red.

[1][2][3]: 152 In the 1150s, the Almohads adopted a large white banner surrounded by a large number of banners and pennants and dubbed it al-'alam al-mansûr, it had become an emblem for the dynasty and acquired an quasi-mystical status.

[1] Ibn Abi Zar describes in his Rawd al-Qirtas of a banner used by the Almohads during the Battle of Alarcos enscribed with the Shahada and Wala ghaliba illa Allah by saying that "when Alfonso VIII had decided to attack Muslims with his entire army [...] he heard the drums and the trumpets, he raised his head to look and saw the Almohad banner approaching; in front of them was a victorious white banner in which was written: there is no deity but Allah, Muhammad is the messenger of Allah, there is no victor except Allah.

[5][6] The Marinid sultanate, who positioned themselves as successors of the Almohads, inherited the 'alam al-mansûr in its form surrounded by other banners.

[8] The al-liwa' al-mansûr, which was also used as a central symbol of al-Mansur's state, also symbolized the central nature of the Makhzen, the continuity of the empire and especially its independence from the Ottoman Empire, and was displayed during all official ceremonies.
