(909 – 1171) Ism
a'
ili Sh
i'ite dynasty of North Africa and the Middle East. Its members traced their descent from
Fatimah, a daughter of the Prophet Muhammad. As Sh
i'ite Muslims, they opposed the Sunnite caliphate of the
'Abbasid dynasty, which they were determined to supplant. From Yemen they expanded into North Africa and Sicily, and in 909 their imam emerged to proclaim the new dynasty. The first four F
atimid caliphs ruled from Tunisia, but the conquest of Egypt in 969 occasioned the building of a new capital, Cairo. At its height, the dynasty controlled Mecca and Medina, Syria, Palestine, and Africa's Red Sea coast. Seeking to overthrow the 'Abb
asids, the F
atimids maintained a network of missionaries and agents in 'Abb
asid territories (
see Assassin). In 1057 – 59 the F
atimid caliph was briefly proclaimed in Baghdad, the 'Abb
asid capital, but F
atimid fortunes declined thereafter. Attacks by Crusaders, Turks, and Byzantines and factionalism in the armed forces weakened the caliphate; disputes over succession to the title of caliph led to the dynasty's final end, however, as many of the Asian missionaries broke away, and the central government came to rely on non-Ism
a'
il
i troops. The last caliph died in 1171, and the dynasty was succeeded by the Sunnite
Ayyubid dynasty.
