Ali ibn Ahmad al-Jarjara'i
As his nisba shows, he came from the locality of Jarjaraya, south of Baghdad. He came to Egypt along with his brother, and held a succession of offices in the Fatimid bureaucracy. He entered the service of Sitt al-Mulk, before becoming secretary to the police chief of Cairo. He was convicted of disloyalty when he opened letters of the secret services in 1013, as a result of which his hands were cut off. However the Caliph al-Hakim soon regretted this harsh punishment, and took him back into the palace and promoted him to high office.
In 1015/6 he was appointed head of the dīwān al-nafaḳāt (bureau of expenditure), before rising to the post of wāsita (the official intermediary between Caliph and the people) in 1021/2, and finally achieving the post of vizier in 1027. He held the post under the caliphs Ali az-Zahir and al-Mustansir until his death in March 1045.
During his tenure, after the pacification of Syria by Anushtegin ad-Duzbirir he concerned himself with improving relations with the Byzantine Empire. A ceasefire had been in place since 1027, and after fresh fighting in 1036 a peace treaty was agreed. The main point of contention was the suzerainty over the Emirate of the Mirdasids in Aleppo, which both powers made claim to. In practice a kind of dual control came into operation.
Under the Caliph al-Mustansir Al-Jarjarai assumed the regency during his minority.
