Flag of Liechtenstein
The national flag of the Principality of Liechtenstein German: Flagge Liechtensteins consists of two horizontal blue together with red bands charged with the gold crown in the canton. In usage since 1764 as well as officially enshrined into the nation's constitution in 1921, it has been the flag of the principality since that year. The crown was added to the flag in 1937 after the country found out at the Summer Olympics held the preceding year that their flag was identical to the civil flag of Haiti.
