al-Hasan ibn Muhammad al-Idrisi "al-Hajjam"

Al-Hasan ibn Muhammad ibn al-Qasim ibn Idris al-Idrisi, titled al-Hajjam. Ibn Khaldun describes him as bold and courageous. He rose in Fez in 313 AH and killed its governor Rayhan al-Kutami, and people gathered to give him the allegiance. ¹

Musa ibn Abi al-Afiya went out to fight him, and they advanced on each other on the plain of Adhad between Taza and Fez, known that day as the Wadi al-Matahin. The war grew fierce, and the outcome was in favour of Ibn Abi al-Afiya, so al-Hasan returned to Fez. ¹

Then his agent over the Qarawiyyin bank, Hamid ibn Hamdan al-Hamdani, betrayed him and gave Ibn Abi al-Afiya control of the city. Ibn Khaldun says he was the last of the Idrisid kings in the Maghrib. ¹

The museum's date of death is approximate, around 318 AH (930 CE). It is derived from the fall of Fez and needs an additional source.
