The Egyptian Free Officers who toppled King Farouk in the Revolution of 1952 assigned specific symbolism to each of the three bands of the revolutionary and liberation flag. The red band symbolizes the Egyptians’ blood in the war against colonization. The white band symbolizes the purity of the Egyptian’s heart. The black band below the white symbolizes the manner in which darkness is overcome.
Egypt’s Revolutionary and Liberation flag was then an inspiration to several Arab countries and was adopted by many Arab states. The same horizontal tricolour is used by Iraq, Syria, Sudan, and Yemen (and formerly Libya), the only difference being the presence (or absence) of distinguishing national emblems in the white band.
As might be expected of a nation of such lengthy recorded history, other flags have played a role in Egyptian politics and society over the years. These historical flags are discussed elsewhere.
