A rebellion in 869 by Ahmad ibn Tulun led to the abandonment of Al Askar and the building of another settlement, which became the seat of government.This was al-Qatta'i ("the Quarters"), to the north of Fustat and closer to the river.With a population of 6.76 million spread over 453 square kilometers (175 sq mi), Cairo is by far the largest city in Egypt.An additional 9.5 million inhabitants live in close proximity to the city.I wrote this HDR photography tutorial over 9 years ago and I update it about every few months. That’s right, the world’s leading HDR photography software has been entirely redesigned with exciting new features, improved user interface, speed improvements, Windows support and more.
For nearly 200 years after Cairo was established, the administrative centre of Egypt remained in Fustat.
The location of the ancient city is the suburb of Ain Shams (Arabic: , "Sun-Eye" or "Eye of the Sun").
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 city's metropolitan area is the largest in the Middle East and the Arab world, and the 15th-largest in the world, and is associated with ancient Egypt, as the famous Giza pyramid complex and the ancient city of Memphis are located in its geographical area.
Located near the Nile Delta, modern Cairo was founded in 969 CE by the Fatimid dynasty, but the land composing the present-day city was the site of ancient national capitals whose remnants remain visible in parts of Old Cairo.
