On 4 January 910, Abū Muḥammad ʿAbd Allāh entered the conquered city of Raqqāḍa in triumph and formally established the Fatimid dynasty. Declaring himself Mahdī, he claimed the eschatological role in Ismāʿīlī doctrine of ending the era of law and ushering humanity into a new age. Scholars have noted how the dynastic succession to the imamate, in contrast with the promise of an imminent end of times, compelled the imām caliphs to reinterpret Ismāʿīlī eschatology, projecting the apocalypse to a distant future. This paper explores how the perceived crisis in messianic expectations arose not from the collapse of a political system, but rather from its consolidation and the unique features of the imām-caliph role: leading a minority religious community while governing a vast, socially and religiously diverse territory.
