Cairo Governorate is the most populated of the governorates of Egypt. Its capital is the national capital of Cairo, and its part of Greater Cairo. Because it is completely urbanized, the governorate is considered a city proper, and functions as a municipality. However, there are uninhabited desert areas.
Parts of the governorate were separated in April 2008 to form the Helwan Governorate (reincorporated into the Cairo Governorate in April 2011).
