The Fatimid Era: History, Cities and Scholarship
Explore Fatimid history (909–1171 CE), Cairo, Al-Azhar, Dar al-Ilm and their connection to the Nizari Ismaili history of Alamut.
Historical scope: the Fatimid heritage before the 1094 succession dispute is shared across later Ismaili traditions. Nizari and Musta'li histories subsequently diverged; competing succession interpretations should be attributed to their respective sources.
A connected chapter of Ismaili history
The Fatimid caliphate began in North Africa in 909 CE under the Ismaili imam-caliph ʿAbd Allah al-Mahdi. Its rulers later established a new capital in Egypt. The legacy of the era includes urban planning, institutions of learning, libraries, religious scholarship and architecture.
For HSKRC, the Fatimid era is the historical background to the later Nizari Ismaili tradition. Following the contested succession in 1094, the Nizari and Mustaʿli branches developed separately; the earlier Fatimid legacy remains part of their shared history.
