In 969 CE, Imam Mu'izz li-Din Allah al-Fatimi sent his brilliant general Jawhar al-Siqilli at the head of the largest Muslim army assembled in centuries to conquer Egypt. Forty days after the conquest, Jawhar founded a new royal capital: al-Qahira al-Mu'izziyya — Cairo the Victorious. The Fatimid Cairo that emerged became one of the greatest intellectual, cultural, and spiritual centers in Islamic history, home to al-Azhar mosque-university, the world's largest library, and the living ta'wil tradition of the Imam.

The Context: The Fatimid Caliphate Before Cairo

The Ismaili Fatimid caliphate was established in North Africa in 909 CE by Imam ‘Ubayd Allah al-Mahdi, who emerged from his concealment in the town of Salamiyya (Syria) and established his capital at Raqqada, near Qayrawan (modern Tunisia). The Fatimid caliphate was the culmination of the Ismaili da’wa’s century-long underground work — a da’wa that had begun in concealment (satr) after the Imam’s disappearance into hiding and that had gradually built a network of followers across the Islamic world.

For six decades, the Fatimid caliphate ruled North Africa from Ifriqiyya (Tunisia/Libya). But from the beginning, the Fatimid Imams had their eyes on a greater prize: Egypt — the ancient agricultural heartland of the Mediterranean, wealthy, strategically positioned between Africa and Asia, with the longest continuous civilizational tradition on earth.

The fourth Fatimid Caliph-Imam, Imam Mu’izz li-Din Allah al-Fatimi (341-365 AH / 953-975 CE), was the one who would finally achieve the conquest of Egypt.

Imam Mu’izz li-Din Allah

Imam Mu’izz li-Din Allah (المعز لدين الله — “He who makes the religion of Allah mighty”) is one of the most remarkable figures in Islamic intellectual and political history.

Intellectual mastery: Imam Mu’izz was himself a theologian, philosopher, and poet of the first rank. He studied with the greatest scholars of his era and personally directed the Fatimid da’wa’s intellectual production. Many of the most important Ismaili philosophical and theological works of the classical period were written at his command or in his court.

The most important scholar in his court: Qadi Abu Hanifa al-Nu’man ibn Muhammad al-Fatimi — the greatest Ismaili jurist, author of Da’im al-Islam — worked directly under Imam Mu’izz and described the Imam as the source of all his knowledge. When Qadi al-Nu’man would read a new work to the Imam, the Imam would correct errors, suggest additions, and guide the work’s direction. Imam Mu’izz’s famous statement: “Whoever acts on one percent of Qadi al-Nu’man’s knowledge, I guarantee him paradise.”

Military vision: Imam Mu’izz recognized that the Abbasid Caliphate in Baghdad was weakening and that the moment for the conquest of Egypt had come. He appointed the most capable general in his army — Jawhar al-Siqilli — to lead the campaign.

Jawhar al-Siqilli and the Conquest of Egypt (969 CE)

Jawhar al-Siqilli (جوهر الصقلي — “Jawhar the Sicilian,” so named because he was of Sicilian origin, possibly a freed slave from Sicily) was the supreme commander of the Fatimid armies under both Imam Mansur and Imam Mu’izz.

The Campaign

In Rabi’ al-Awwal 358 AH (January 969 CE), Jawhar set out from the Fatimid capital with an army variously described as 100,000-150,000 strong — the largest military expedition in the Islamic world in generations. The expedition was:

Egypt in 969 CE was ruled nominally by the Ikhshidid dynasty, but the actual power structure had collapsed. The Ikhshidid regent died; rival factions competed for control; famine had weakened the Egyptian population. Jawhar’s army met minimal resistance.

Ramadan 358 AH (July 969 CE): Jawhar entered Egypt and accepted the surrender of Fustat (Old Cairo) within days. Egypt fell to the Fatimids essentially without major battle — a testament to both Jawhar’s military skill and the political preparation that had preceded him.

Jawhar’s Proclamation

After the conquest, Jawhar issued a proclamation (aman — guarantee of safety) to the Egyptian population that was notable for its generosity:


The Founding of Al-Qahira — Cairo

Immediately after securing Egypt, Jawhar began construction of a new royal city north of the existing city of Fustat. The new city was to be the capital of the Fatimid empire in Egypt — a purpose-built imperial capital for the Imam.

The Name: Al-Qahira

The city was named al-Qahira al-Mu’izziyya — “the Victorious, the city of Mu’izz.” The name al-Qahira (القاهرة — the Victorious, the Overwhelming) is said to derive from:

Modern Cairo takes its name from this Fatimid foundation — Cairo is the Anglicized form of al-Qahira.

The Foundation Legend

The tradition records that when Jawhar’s surveyors had prepared the foundation trench and strung ropes with bells (to be rung when the astrologers determined the auspicious moment to begin construction), a raven or crow (according to different versions) caused the bells to ring before the appointed time — when the planet Mars (al-Qahir) was rising. Whether historical or legendary, this account explains the city’s name.

Urban Plan of Fatimid Cairo

Jawhar designed al-Qahira as a walled royal city with:

The common people of Egypt continued to live in Fustat to the south. Al-Qahira was reserved as the royal-administrative city — a practice that would change only after the Fatimid dynasty’s end, when Salah al-Din (Saladin) opened the city to the general population.


Imam Mu’izz’s Arrival in Cairo (973 CE)

Imam Mu’izz li-Din Allah remained in North Africa for four years after the conquest, completing the administrative transition of the Fatimid court to its new base. In 362 AH (973 CE), he made the journey to Egypt with:

The Imam’s arrival in Cairo marked the formal establishment of Cairo as the capital of the Fatimid Caliphate. Egypt would remain the Fatimid heartland for the next two centuries (until 1171 CE).


Al-Azhar: The Mosque and the University

Al-Jami’ al-Azhar (الجامع الأزهر — the Resplendent Mosque) was the first major building completed in al-Qahira, finished in 972 CE. Al-Azhar was not simply a mosque — it was from the beginning conceived as an intellectual and educational institution for the propagation of the Ismaili da’wa.

Name and Significance

Al-Azhar derives from zahir (bright, resplendent) and is also understood as a title of Sayyidatna Fatima al-Zahra (AS) — the Prophet’s daughter, from whom the Fatimid dynasty claimed descent. The mosque was thus named in her honor.

Function Under the Fatimids

Under the Fatimids, al-Azhar served as:

The Majalis al-Hikmah were a unique Fatimid institution — open public teaching of the inner dimensions of Islamic theology. Qadi al-Nu’man’s Kitab al-Majalis wal-Musayarat records many of the Imam’s own teaching sessions.

Al-Azhar After the Fatimids

When Salah al-Din al-Ayyubi (Saladin) ended the Fatimid Caliphate in 1171 CE, he transformed al-Azhar’s orientation from Ismaili to Sunni Shafi’i. Al-Azhar subsequently became the greatest center of Sunni Islamic learning in the world — a position it still holds today.

The institution that Imam Mu’izz and Jawhar built to propagate Ismaili ta’wil became the most prestigious Sunni university in the world — a historical irony that does not diminish al-Azhar’s Fatimid origin.

The Fatimid Palace and the Great Library

The Twin Palaces

The Fatimid royal complex in Cairo consisted of two great palaces facing each other across a ceremonial square capable of holding 10,000 soldiers at parade:

These were not merely residences but centers of an elaborate ceremonial culture that combined religious meaning with political theatre. The Imam’s public appearances (dar al-‘amm) were carefully structured ritual events through which the community encountered the Imam’s presence.

The Dar al-‘Ilm and the Library

The Fatimid Cairo maintained what was probably the largest library in the Islamic world at that time:

The Dar al-‘Ilm (House of Knowledge) was a public library and academic institution founded by Caliph al-Hakim bi-Amr Allah (386-411 AH / 996-1021 CE). It contained:

The Dar al-‘Ilm was a remarkable institution — open to scholars of all backgrounds, providing free education and books. When the Crusaders and Saladin’s forces eventually ended the Fatimid era, accounts describe the library’s contents being dispersed across the entire Muslim world.


The Fatimid Cairo: Center of Ta’wil

For the Ismaili and Bohra tradition, Fatimid Cairo’s deepest significance is not architectural or political but intellectual and spiritual: it was the era in which the Imam’s living presence made possible the fullest articulation of Ismaili ta’wil.

Imam Mu’izz personally taught ta’wil and directed its formulation through Qadi al-Nu’man and other scholars.

Imam al-‘Aziz (365-386 AH) continued the scholarly project; it was in his era that the philosopher-da’i Abu Ya’qub al-Sijistani produced major ta’wil texts.

Imam al-Hakim (386-411 AH) founded the Dar al-‘Ilm and enabled the philosopher Hamid al-Din al-Kirmani to produce the Rahat al-‘Aql — the most systematic Ismaili philosophical work.

Imam al-Mustansir (427-487 AH) — who reigned for 60 years, the longest reign of any Fatimid caliph — saw the era of the great da’i Nasir-i Khusraw, who traveled from Khorasan to Cairo to meet the Imam and returned transformed, founding the Ismaili da’wa in Persia and Central Asia.

The living ‘ilm that flowed from Imam to da’wa to community in Fatimid Cairo shaped every dimension of Ismaili intellectual culture — including the Bohra tradition that is the direct heir of this Fatimid legacy.

Legacy: Fatimid Cairo Today

The physical remains of Fatimid Cairo are still visible in modern Cairo’s Islamic Quarter (now a UNESCO World Heritage site):

The restoration of the Al-Hakim mosque by the Dawoodi Bohra community is a living act of connection between the contemporary Bohra community and its Fatimid heritage — restoring what Imam al-Hakim built, as a gift from the community to the city of Cairo.
