colour green was itself strongly associated with nationalism in Egypt, particularly due to its use on the banner of the Egyptian Revolution of 1919. As the subsequent revolution of 1952 was explicitly committed to both Egyptian and Arab nationalism, Naguib and Nasser insisted on the inclusion of green on revolutionary Egypt's coat of arms, and national flag. When Egypt united with Syria to form the United Arab Republic in 1958, the appearance of the eagle was modified, replacing the monarchical green field and white crescent and stars on the eagle's breast with an escutcheon bearing a vertically rotated flag of the United Arab Republic with two green stars in the central white band representing the two constituent members of the union. In the eagle's talons was placed the official name of the state on a green scroll, thereby, along with the green stars, incorporating once again the colour green on the coat of arms. Whilst the eagle was replaced at the centre of the Arab Liberation Flag by the two green stars, its status as the union's coat of arms meant that it appeared on all state buildings, documents, and uniforms. Following Egypt's membership of the Federation of Arab Republics in 1972 during the presidency of Anwar Sadat, the Eagle of Saladin was replaced entirely as Egypt's coat of arms by the Hawk of Quraish, which would also take the place of the two green stars in the centre of the national flag. In both policies and symbolism, Sadat was eager to depart from the path of his predecessor, Gamal Abdel Nasser, resulting in the adoption of a new coat of arms, and a modified flag, both of which excluded the colour green. The federation, however, was short-lived, dissolving in 1977. Sadat himself was assassinated in 1981. In 1984, the Eagle of Saladin was restored as Egypt's coat of arms, and has remained as such since, with the eagle returned to the central white band of the national flag. The appearance of the eagle when re-adopted remained the same as the 1958 version with the exception of it being rendered entirely in gold and white, save for the escutcheon on the eagle's breast, which continues to bear the vertically rotated red-white-black bands of the national flag. Consequently, the changes to Egypt's heraldic colours by Sadat were made permanent, and the current design of Egypt's coat of arms (and national flag)
