For nearly 200 years after Cairo was established, the administrative centre of Egypt remained in Fustat.
Originally a tented camp (Fustat signifies "City of Tents") Fustat became a permanent settlement and the first capital of Islamic Egypt.
In 750, following the overthrow of the Ummayad caliphate by the Abbasids, the new rulers created their own settlement to the northeast of Fustat which became their capital.
The ancient Egyptian name for the area is thought to be Khere-Ohe, "The Place of Combat", supposedly in reference to a mythical battle that took place between Seth and Horus.
The area around present-day Cairo, especially Memphis, had long been a focal point of Ancient Egypt due to its strategic location just upstream from the Nile Delta.
Cairo is considered a World City with a "Beta " classification according to Ga WC.
Cairo has the oldest and largest film and music industries in the Arab world, as well as the world's second-oldest institution of higher learning, Al-Azhar University.Continuing a practice started by the Ayyubids, much of the land occupied by former Fatimid palaces was sold and replaced by newer buildings.Meanwhile, Cairo flourished as a centre of Islamic scholarship and a crossroads on the spice trade route among the civilisations in Afro-Eurasia.An additional 9.5 million inhabitants live in close proximity to the city.Cairo, like many other mega-cities, suffers from high levels of pollution and traffic.However, the origins of the modern city are generally traced back to a series of settlements in the first millennium.
