Fatimid Caliphate
The Egyptian city of Cairo was made the capital. The term Fatimite is sometimes used to refer to the citizens of this caliphate as well. The ruling elite belonged to the Ismaili branch of Shi'ism. The leaders were also Shia Ismaili Imams. They had a religious significance to Ismaili Muslims. They are also part of the chain of holders of the office of Caliph, as recognized by most Muslims, the only period in which the Shia Imamate and the Caliphate were united to any degree. There was only one other exception: the Caliphate of Ali himself.
