Qatar
What the source says
Referenced, awaiting primary-source reviewOfficially adopted on 9 July 1971, with a slight colour change from an earlier flag adopted from 1949. Maroon reflects the nation's rich heritage in purple dye production - a craft that dates back to the Kassite and Sasanian periods; white signifies peace. The nine-point serrated line represent[s] Qatar's position as the ninth reconciled emirate to sign the 1916 Qatari-British treaty. Qatar's flag is the only national flag having a width more than twice its height.

Colors and meaning
Symbolism and history(r1)
A serrated line of nine white points — marking Qatar as the ninth "reconciled emirate" to sign the 1916 treaty with Britain — divides a broad maroon field from a white hoist band; it is the only national flag whose width is more than twice its height.
