The current flag of Sudan was adopted on 20 May 1970 and consists of a horizontal red-white-black tricolour with a green triangle at the hoist. The flag is based on the Arab Liberation Flag of the Egyptian Revolution of 1952, as are the flags of Egypt, Iraq, Syria, Yemen, and Palestine and formerly of the United Arab Republic, North Yemen, South Yemen, and the Libyan Arab Republic.

The national flag of Egypt is a tricolour consisting of the three equal horizontal red, white, and black bands of the Egyptian revolutionary flag that dates back to the 1952 Egyptian Revolution. The flag bears Egypt's national emblem, the Egyptian eagle of Saladin, centred in the white band.
