Fatimid Caliphate Bureaucracy

Timeline

1. 969–1035Cairo · CairoAfter conquering Egypt, the Fatimids set up institutions such as the dīwān al-insha (chancery) and the dīwān al-amīr al-kabīr (vizier's office), with kātib families like the Banu al-Tahir handling taxation, diplomacy, and archives, forming a Shia bureaucratic tradition distinct from the Abbasid model.
2. 1051–1060Cairo · CairoIn the mid-reign of al-Mustansir (r. 1036–1094) in the 1050s, the dīwān system still managed Nile irrigation finances, the Syrian frontier, and Red Sea trade; but Turkish and Sudanese military slave regiments grew in size, and the balance of power between civilians and military commanders began to tilt, foreshadowing the later militarization of the vizierate.
3. 1074–1171Cairo · CairoAfter the general Badr al-Jamali became vizier in 1074, the Fatimid bureaucracy was militarized, with the vizier holding both administrative and military power; thereafter, although the dīwān institutions continued in form, real power concentrated in the military elite until Saladin abolished the Fatimid caliphate in 1171.
