Cairo Arabic al-Qahira (meaning ‘victorious’), The capital city of Egypt and the most populous city in the continent of Africa. The city has significant cultural importance, particularly in Islam. It was founded by the Fatimids in 969 and fortified with the hilltop citadel in 1176 by Saladin. The city flourished under the Mamluks (13th to 16th century), who erected splendid mosques, khans, khanqahs (Sufi lodges) and madrassas for religious education; it is home to the al-Azhar University, one of the leading centres of Islamic study as well as secular study.

It remains a major cultural and educational centre for the Arab and Islamic worlds.
caliph A name given to dynastic rulers of the Muslim world which is a reference to their status as successors of the Prophet Muhammad. After semi-democratic choices for the first caliphs (they were chosen by elders), the caliphate became hereditary and from these beginnings two long-lasting dynasties, the Umayyads and Abbasids, were to emerge. Although the role of caliph is military and administrative rather than religious, the role does implicitly demand an adherence to Islam and the need to spread the religion over its sphere of rule, known as the caliphate.
