The Fatimid caliphs-imams developed the daʿwa into a highly organized system and disciplined school, in which the term dāʿī also referred to a specific rank in the Fatimid religious hierarchy. However, prior to the Fatimid caliphate, the term dāʿī was equally applicable to those who summoned people towards the Ismaili imams of the time.
