The flag of Qatar (Arabic: عَلَمْ قَطَرْ) is in the ratio of 11:28. It is maroon with a broad white serrated band (nine white points) on the hoist side. It was adopted shortly before the country declared independence from the United Kingdom on 3 September 1971. The triangle edges represent Qatar as the 9th " reconciled emirate". The flag is similar to the flag of Bahrain, which has fewer points, a 3:5 proportion, and a red colour instead of maroon. Qatar's flag is the only national flag having a width more than twice its height.
