Pan-Arab colors
The inspiration for these new colors can be traced back to the Arab Liberation flag that was in use during the 1952 Egyptian Revolution (also called the July 23 revolution). The revolution was led by two army officers, namely Gamal Abdel Nasser and Mohammed Naguib, who wanted to do away with the reign of King Farouk. The new colors appear today in several flags. These flags include those of Egypt, Syria, Yemen, Sudan, Iraq, and Yemen. Even before Yemen merged, the rival states that made up the larger Yemen, North and South Yemen, both had the colors in their respective flags. There were also Arab unions that did not last very long but had the Arab Liberation colors. These unions were the Federation of Arab Republics and the United Arab Republic.
