Cairo is the capital of  Egypt. It is also the largest city in the Arab world.

The Greater Cairo metropolitan is the largest urban agglomeration in Africa, the largest in the Arab world and the Middle East, and the sixth-largest in the world by population. Cairo is associated with ancient Egypt, as the Giza pyramid complex and the ancient cities of Memphis and Heliopolis are located in their geographical area. Located near the Nile Delta,[11][12] the city first developed as Fustat, a settlement founded after the Muslim conquest of Egypt in 640 next to an existing ancient Roman fortress, Babylon. Today, Cairo has the oldest and largest cinema and the music industry in the Arab World, as well as the world's second-oldest institution of higher learning, Al-Azhar University. Many international media, businesses, and organizations have regional headquarters in the city; the Arab League has had its headquarters in Cairo for most of its existence.
