The colours of the Iranian flag are traditional, probably dating from at least the 18th century, and they can be interpreted as representing the Islamic religion (green), peace (white), and courage (red). They were first designed in tricolor form in 1907. The flag's centerpiece formerly comprised a lion with a sword standing before a rising sun, with a crown above, but all traditional flags and banners were abolished after the abdication of the shah in 1979.
The Syrian flag incorporates the four pan-Arab colors, which represent the various dynasties that ruled the region in history. The combination of colors was first used to represent the region during the 1916 Arab Revolt. The red symbolizes the Khawarij, an Islamic group of the seventh century, whose flag was red. The red also symbolizes the Hashemites. The white represents the Umayyad Dynasty, who used white as their color of mourning.
