Yemen Flag - Facts
The Flag of Yemen was adopted on May 22, 1990, the day that North Yemen and South Yemen were unified. The flag is essentially the Arab Liberation Flag of 1952, introduced after the Egyptian Revolution of 1952 in which Arab nationalism was a dominant theme. The Arab Liberation Flag served as the inspiration for the flags of both North and South Yemen prior to unification, as well as for the current flags of Egypt, Iraq, Sudan, and Syria.
