Cairo — The City Victorious

Introduction: Al-Qahirah, The Victorious

Cairo (القاهرة, al-Qahirah) is the largest city in Africa and the Arab world, home to over twenty million people in its metropolitan area. Its name — "the Victorious" or "the Subduer" — was chosen by the Fatimid general Jawhar al-Siqilli upon founding the city in 969 CE, reportedly because the planet Mars (al-Qahir in Arabic) was rising at the moment construction began. Cairo has served as the capital of Egypt through Fatimid, Ayyubid, Mamluk, Ottoman, and modern periods of Islamic history, and it has been home to al-Azhar University — arguably the oldest continuously operating university in the world — since the Fatimid period.

Pre-Islamic and Early Islamic Egypt

Egypt was conquered by the Muslim armies under Amr ibn al-As in 640-641 CE, during the caliphate of Umar ibn al-Khattab. The conquest was swift and relatively peaceful. Amr established his capital at Fustat, near the southern tip of modern Cairo, rather than at the ancient city of Alexandria. Fustat grew into a prosperous city and remained the administrative center of Islamic Egypt for centuries. The Mosque of Amr ibn al-As, built in 641 CE, is considered the oldest mosque in Africa still in use. Fustat was burned in 1168 CE by the Fatimid vizier Shawar to prevent its capture by Crusader forces, leaving it a ruin.

The Fatimids and the Founding of Cairo

The Fatimid Caliphate — an Ismaili Shia dynasty — conquered Egypt in 969 CE and founded al-Qahirah as their new capital immediately north of Fustat. The Fatimids established al-Azhar Mosque in 970 CE as the center of their religious and educational program. Al-Azhar was expanded over subsequent centuries and gradually evolved into a comprehensive institution of Sunni Islamic learning — particularly after Saladin ended Fatimid rule in 1171 CE and redirected al-Azhar toward Sunni scholarship. Al-Azhar today remains one of the most influential Islamic educational institutions in the world, attracting students from dozens of countries and issuing religious opinions that carry weight across the Muslim world.

Saladin and the Ayyubids

Salah al-Din al-Ayyubi (Saladin) came to power in Egypt in 1169 CE as the Fatimid vizier and within two years had ended the Fatimid Caliphate, restoring Egypt to Sunni Islam under nominal Abbasid suzerainty. Saladin built the Citadel of Cairo — still a major Cairo landmark — as his seat of government and a defensive structure. He also constructed a wall enclosing Fustat, the older settlements, and the Fatimid city into a unified Cairo. Saladin is remembered in Egypt not only for his liberation of Jerusalem but for his administrative reforms, his patronage of scholarship, and his establishment of schools and hospitals. After his death in 1193 CE, the Ayyubid dynasty continued to rule Egypt until displaced by the Mamluks.

The Mamluks: Cairo at Its Medieval Peak

The Mamluk Sultanate (1250-1517 CE) represents one of the high points of Cairene civilization. The Mamluks — a warrior class of enslaved soldiers, primarily of Turkic and Circassian origin, who had risen to political dominance — proved to be extraordinary builders and patrons of Islamic culture. They defeated the Mongol advance at the Battle of Ain Jalut in 1260 CE — the first major Mongol defeat — protecting Egypt and North Africa from the devastation that had struck the eastern caliphate. Cairo under the Mamluks was the most important city in the Islamic world: host to the Abbasid Caliphate in exile (after the Mongol destruction of Baghdad), a major center of Islamic scholarship, and one of the most architecturally productive cities in history. The Mamluk mosques, mausoleums, and madrasas of medieval Cairo — concentrated in the area around the Citadel and the Khan al-Khalili bazaar — constitute one of the world's most significant concentrations of medieval Islamic architecture.

Ottoman and Modern Cairo

Egypt was conquered by the Ottoman Sultan Selim I in 1517 CE, and Cairo became a provincial capital within the Ottoman Empire. The Ottoman period saw the construction of additional mosques and the continuation of Cairo's commercial importance, though the city's political centrality in the Islamic world diminished compared to the Mamluk era. In the modern period, Cairo became the capital of an independent Egypt and remains the most important city in the Arab world — home to al-Azhar, the Arab League, major media institutions, and a cultural output that reaches every Arabic-speaking country. The historic core of Islamic Cairo — with its over six hundred listed monuments — was designated a UNESCO World Heritage Site in 1979 and remains one of the most significant urban repositories of Islamic heritage anywhere.
