His Reign in North Africa
Al-Mu’izz ascended to the Imamate and Caliphate in 341 AH / 953 CE, succeeding his father al-Mansur. He had already served as crown prince and was well-prepared for the task. His first priorities were:
- Consolidating North Africa: After the devastating Abu Yazid rebellion (which had threatened the Fatimid state during al-Mansur’s reign), al-Mu’izz rebuilt Fatimid authority across the Maghreb and extended it further into Morocco
- Cultivating the da’wa network: He invested heavily in his network of da’is (missionaries) spreading through the Islamic world — into Iraq, Syria, and the Indian subcontinent — preparing the intellectual and political ground for expansion
- Patronizing knowledge: His court in al-Mahdiyya (North Africa) became a center of extraordinary intellectual activity — philosophy, astronomy, mathematics, medicine, and esoteric theology
Intellectual partnership with al-Mu’ayyad: The great da’i and theologian al-Mu’ayyad fi’l-Din al-Shirazi was among al-Mu’izz’s intellectual companions, contributing to the development of Ismaili ta’wil during this period.

The Conquest of Egypt (969 CE)
Al-Mu’izz’s supreme strategic achievement was the conquest of Egypt — the wealthiest and most politically significant territory in the Islamic world. The conquest was accomplished by his Sicilian-born general Jawhar al-Siqilli (Jawhar the Sicilian).
The campaign: Jawhar marched from al-Mahdiyya with an army reportedly numbering 100,000 men (a possibly exaggerated figure, but certainly a massive force). The Ikhshidid rulers of Egypt offered only minimal resistance. Jawhar entered Fustat (the then-capital of Egypt) in 358 AH / 969 CE — entering a city whose population came out to greet him with minimal bloodshed.
The new city: Jawhar immediately began construction of a new walled royal city north of Fustat — called al-Qahira al-Mu’izziyya (The Victorious — of al-Mu’izz). Al-Qahira = Cairo. The name was chosen partly because Mars (al-Qahir — the conquering planet) was in the ascendant when construction began, and partly because the city was named for the Imam al-Mu’izz himself.
Al-Azhar’s foundation: Within the walls of the new city, Jawhar built the Friday mosque that would become al-Azhar — named for Sayyidatna Fatima al-Zahra, the Imam’s ancestor.

Al-Mu’izz Enters Cairo (973 CE)
Four years after the conquest, al-Mu’izz himself relocated from North Africa to Cairo — a momentous journey that transferred the center of the Fatimid Imamate-Caliphate permanently to Egypt.
The famous meeting: When al-Mu’izz arrived in Cairo, he gathered the scholars and notables who challenged his lineage — demanding proof of his Fatimid ancestry. Al-Mu’izz drew his sword and said: “This is my genealogy!” He then opened his treasury and distributed gold to the crowd: “And this is my noble birth!” — a story that captures the pragmatic grandeur of his rule.
The relocation of the Imam’s ancestors: Al-Mu’izz brought the remains of his Fatimid ancestors from North Africa to Cairo, burying them in the new capital. This symbolic act completed the transfer: Cairo was now the seat of the Imams.
The encounter with Qadi al-Nu’man: The great Ismaili jurist Qadi al-Nu’man ibn Muhammad, who had served al-Mu’izz for decades, died in 974 CE in Cairo — one year after the Imam’s arrival. Their decades-long collaboration had produced the Da’a’im al-Islam (The Two Pillars of Islam), the foundational legal code of the Fatimid state and the Tayyibi da’wa.

The Ismaili Da’wa Under al-Mu’izz
Al-Mu’izz was not merely a political ruler; he was actively engaged in the da’wa’s intellectual and spiritual dimensions:
His own writing: Al-Mu’izz wrote theological poetry and is credited with treatises on Ismaili ta’wil. His correspondence with da’is across the world reveals a ruler deeply engaged with the theological details of Ismaili teaching.
The da’wa expansion: Under his patronage, the Ismaili da’wa made significant advances in Yemen, the Indian subcontinent, and continued its deep penetration into Iraq and Syria. The da’wa’s intellectual infrastructure expanded in al-Mu’izz’s reign.
The misaq renewal: Al-Mu’izz reinforced the Ismaili misaq (covenant) throughout the community — the binding covenant of allegiance that links every believer, through the chain of da’wa, to the Imam.

Legacy
Al-Mu’izz died in 365 AH / 975 CE in Cairo, having reigned for 22 years. His successor, al-‘Aziz bi-Allah, inherited a Caliphate at the peak of its power and a city — Cairo — that would be the Fatimid capital for nearly two centuries.
Al-Mu’izz li-Din Allah is remembered in Ismaili tradition as one of the greatest of the Imam-Caliphs — the one who brought the Imam out of North African provinciality into the center of Islamic history, who built Cairo and al-Azhar, who maintained the highest intellectual tradition of the da’wa, and who exemplified the Imam’s dual nature: the pragmatic ruler who used worldly power in service of the divine’s design.
