What happened
The Fatimids, an Ismaili Shia dynasty that traced its claimed descent from Fatima, Muhammad's daughter, and her husband Ali, had built a rival caliphate in North Africa from 909 CE, directly challenging the Abbasids' claim to sole leadership of the Islamic world. In 969 CE the Fatimid caliph al-Mu'izz conquered Egypt, and by 973 CE he had established Cairo (al-Qahira, the Victorious) as his new capital, replacing the older nearby cities of Fustat and al-Askar as Egypt's center of power. Within Cairo, the Fatimids built the mosque of al-Azhar, completed in 972 CE, which soon developed beyond a congregational mosque into a seat of learning that became the foremost center of Shia Ismaili scholarship before later becoming a major Sunni institution after the twelfth century.
Why it matters
Cairo's founding gave the Islamic world a second major caliphate and capital rivaling Baghdad, formalizing a three-way split in Islamic political leadership alongside the Abbasids in Baghdad and the Umayyad successor state in Cordoba. Al-Azhar's evolution into a center of learning made Cairo an intellectual rival to Baghdad that has continued as a center of Islamic scholarship into the present day.
How we know
The founding of Cairo and al-Azhar's role are documented by UNESCO's World Heritage inscription for Historic Cairo and corroborated by the Institute of Ismaili Studies, an academic research institute affiliated with the Aga Khan University.
