The current flag of Comoros was adopted in 2001. Former flags have consisted of a crescent on a green field. The new design retains the crescent but places it within a green triangle. In addition, four stripes were added to symbolize the four islands of the nation: yellow is for Mohéli, white for Mayotte, red for Anjouan, and blue for Grande Comore. The four stars next to the crescent also stand for the islands, while the crescent stands for Islam, which is the major religion on Comoros.
