Al-Zafir

Abu Mansur Isma'il al-Zafir bi-Amr Allah, February 1133 – April 1154), was the twelfth Fatimid caliph, reigning in Egypt from 1149 to 1154, and the 23rd imam of the Hafizi Ismaili sect.
Life.
The future al-Zafir was born in late February 1133 as the fifth son of the eleventh Fatimid imam-caliph, al-Hafiz li-Din Allah (). As all his older brothers predeceased their father, al-Zafir was appointed heir-apparent. Al-Zafir was proclaimed caliph immediately after his father's death, on 10 October 1149.
To calm the rival military factions of the Turks and Black Africans, who were clashing in the streets of Cairo, a generous donative was distributed and promises were made to look after them. The situation was brought under control in November, when the vizier, Ibn Masal, executed the faction leaders. Al-Zafir then turned to the pleasures of his harem, but a revolt by the governor of Alexandria, Ibn al-Sallar, overthrew Ibn Masal. After being recognized as vizier by the caliph, Ibn al-Sallar had his predecessor executed. 
The imam-caliph al-Zafir was murdered by his vizier, Abbas ibn Abi al-Futuh and his son Nasr, who succeeded Ibn al-Sallar. Al-Zafir never exercised power in his own right, with his viziers exercising real power. Instead of devoting himself to the administration, al-Zafir exceedingly inclined to a life of pleasure. He was murdered at the age of 21 years in 1154 and was succeeded by his five-year-old son, al-Faiz.
