Through Muslims, Cairo and Caliphate

The caliph al-Mustanṣir bi-llāh was the last Imam before a disastrous split divided the Isma'ili movement in two, due to the struggle in the succession between al-Mustansir's older son, Nizar, and the younger al-Mustaʽli, who was raised to the throne by Badr's son and successor, al-Afdal Shahanshah. The followers of Nizar, who predominated in Iran and Syria, became the Nizari branch of Isma'ilism, while those of al-Musta'li became the Musta'li branch.

Biography

Al-Mustansir was born in Cairo on 16 Jumada II 420 AH / 2 July 1029, to Ali az-Zahir and Rasad, a black slave from Nubia. At the age of only eight months he was declared the heir of his father. His name was Abu Tamim Maʿad, surnamed al-Mustansir Bi'llah ("The Asker of Victory from God"). He ascended to the Fatimid Caliphate's throne on 15 Sha'ban 427 / 13 June 1036 at the age of 7. During the early years of his Caliphate, state affairs were administered by his mother. His rule lasted for 60 years, the longest of all the caliphs, either in Egypt or elsewhere in Islamic states. However, Fatimid power was confined to Egypt due to conquests of the Seljuks in the Levant, Normans in Sicily and Malta, and by Arab tribes destabilizing Fatimid control over Tunisia and Tripoli. Al-Mustansir was considered incapable and as such his court was dominated by military strongmen and his mother's favourite officials, while the treasury was exhausted by factional infighting.

He had constructed a special mihrab at one of the pillars in the Mosque of Ibn Tulun. Atop the mihrab, his name is engraved along with the Shahada commonly recited by the public in the Fatimid era ending with the phrase 'Ali-un Wali-u Allah, meaning "Ali is the steward of God".

His Court

Prominent Dais/Vizirs of his era are as follows:

  • Ali bin Ahmad Jarjarai, vizier (d. 1045)
  • Badr al-Jamali, vizier (d. 1094)
  • Mu'ayyad fi'l-Din al-Shirazi, chief missionary (dā‘i al-dū‘at) from 1059 to 1078

Moulai Abadullah and Syedi Nuruddin were two Indians who visited al-Mustansir Billah in Egypt. They joined the Ismaili faith under Fatimid Dai Mu'ayyad fi'l-Din al-Shirazi, and went to India to propagate the faith.

Ismaili da'wa under him

During the reign of the Imam al-Mustanṣir, the Ismaili da'wa (“ministry”) was led, in the eastern regions, by Abd al-Malik ibn Attash, who was based in Iṣfahān. He also enjoyed good relations with the Druze community which were persecuted by the two previous Fatimid caliphs as they were seen as a heretical offshoot of Ismailism.

Ibn al-Athīr (a Sunni historian) describes Abd al-Malik (Ibn Attash) as being interested in works of literature, and being a professional calligrapher. He continues by describing him as a clever, intelligent and quick thinker, and an ethical man.

One of Ibn Attash's most notable students, Ḥasan-i Ṣabbāḥ became an important figure and was selected as the ḥujja or “proof” of al-Mustanṣir. This position/rank was right below the Imam in the Ismaili religious hierarchy. He would go on to found the Nizari sect.

Construction projects

Prominent buildings constructed during the reign of al-Mustansir are as follows:

  • Bab al-Futuh
  • Bab al-Nasr
  • Bab Zuweila
  • Juyushi Mosque
