The pre-modern history of the Isma’ili Shi’i sect of Islam has typically been shrouded in mystery or distorted through fantasy. This is as true of its origins in dispute over the rightful successor to Ja’far al-Sadiq, the sixth in a genealogical line from the Prophet’s family of imams or divinely guided religious and political leaders of the early Shi’ah community, as it is of medieval Isma’ili history after the fall of the Fatimid dynasty’s rule in Egypt and the Levant.
