al-Musta'sim bi'llah Abdullah ibn al-Mustansir, last caliph of Baghdad

Abbasid caliph [640–656], the last of Baghdad — raised over his fierce uncle al-Khafaji for his softness, that the duwaydar and sharabi might rule. Empty of counsel, he cut most of the host his father had mustered on al-Alqami's advice, while the vizier wrote secretly to the Tatars meaning to move the caliphate to the Alids — 'and al-Musta'sim wandered in his pleasures'.
