The national flag of Egypt (Arabic: عَلَمْ مِصر ˈʕælæm mɑsʕɾ) 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.
In 1952, the Egyptian Free Officers who toppled King Farouk in the 23 July Revolution assigned specific symbolism to each of the three bands of the revolutionary and liberation flag. The red band symbolizes the Egyptians’ bloods in the war against colonization. The white band symbolizes the purity of the Egyptians’ hearts. The black band below the white symbolizes the manner in which darkness is overcome.
Egypt's Revolutionary and Liberation flag, which was designed on 23 July 1952, 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.
The development of the modern Egyptian flag was determined first by the Muhammad Ali Dynasty, under whom Egypt was united with Sudan, and later by the rise of Egyptian nationalism and revolutionary ideas among the Egyptian Army.
When Muhammad Ali successfully seized power in Egypt, at that time the country was officially an Eyalet (Cum Eyalet) of the Ottoman Empire. However, throughout his reign, and that of his sons and grandsons, Egypt enjoyed virtual independence as an own Khedivate. The meaning of the three stars and crescents has been suggested that this was to symbolise the victory of his armies in three continents (Africa, Asia, and Europe), and his own sovereignty over Egypt, Sudan, and Hejaz. The similarity with the flag of the Ottoman Empire was deliberate, as Muhammad Ali harbored grandiose ambitions of deposing the Ottoman dynasty, and seizing the sultanic throne himself.
