History of the Republic of Egypt
On 22–26 July 1952, the Free Officers, a group of disaffected officers in the Egyptian army founded by Gamal Abdel Nasser, and headed by General Muhammad Naguib, initiated the Egyptian Revolution of 1952 with the overthrowing King Farouk, whom the military blamed for Egypt's poor performance in the 1948 war with Israel and lack of progress in fighting poverty, disease, and illiteracy in Egypt. In the following two years, the Free Officers consolidated power, and, following a brief experiment with civilian rule, abrogated the 1953 constitution, and declared Egypt a republic on 18 June 1953, Muhammad Naguib as Egypt's first President.
Flag of Egypt
Following the Revolution of 1952, the Egyptian free officers retained the flag of the Kingdom, but also introduced the Revolutionary and Liberation flag of red, white, and black horizontal bands, with the emblem of the Revolution, the Eagle of Saladin, in the center band. This earlier version of the eagle differs somewhat from the one later adopted. Even when the Kingdom was formally abolished by the declaration of the Republic on July 18, 1953, the flag of the Kingdom remained in official use until Gamal Abdel Nasser announced the formation of the United Arab Republic in 1958.
