al-Qa'im bi-Amr Allah Hamza ibn al-Mutawakkil

Al-Qa'im bi-Amr Allah Abu al-Baqa Hamza ibn al-Mutawakkil, an Abbasid caliph in Cairo from 854 to 859 AH. He was given the allegiance after his brother, and no one had appointed him or anyone else. ¹

Al-Suyuti describes him as chivalrous and stern. He briefly upheld the dignity of the caliphate, and had a severity unlike his other brothers. He invested Uthman ibn Jaqmaq as al-Mansur, and then al-Ashraf Inal when he rose against him. ¹

A dispute arose between him and al-Ashraf because the soldiers rode against him. Al-Ashraf deposed him in Jumada 859 AH, sent him to Alexandria, where he was held until he died in 863 AH at about seventy years old. He was buried beside his brother al-Musta'in; both had been deposed and held in Alexandria, and they were buried together. ¹

Ibn al-Imad says that he was given the allegiance on the fifth of 855 AH after the death of his brother al-Mustakfi billah Sulayman. ²

• The dates of the allegiance between 854 and 855 AH differ between the two sources, and need an additional source.
