The Fatimid History of al-Azhar Mosque:
Al-Hakim bi Amr Allah: (996-1021) The third Fatimid caliph in Egypt and perhaps the most enigmatic and most controversial.
Ya`qub ibn Killis: The vizier and able administrator of al-Aziz and the designer of early Fatimid processions. He formalized the role of the imam as the supreme head of the community. He was also the first to regularize the educational function of the congregational mosque in Cairo.
Characteristics of Fatimid mosque architecture:
Al-Hakim Mosque: Built between 990 and 1003 just outside the walls of al-Qahira, and named after al-Hakim, the third Fatimid caliph in Egypt.
The Mosque of al-Lu'lu'a: (1015-16) One of many small mosques on the Muqattam cliff attributed to al-Hakim.
