Thailand

The story goes that during the 1916 flood the king of Siam (since 26th June 1939 called Thailand) saw the national flag (red with a white elephant) hanging upside down. Because of the distress this caused the King a new flag was adopted that could not be hung upside down. Initially it was a red field with two white bands, but on 28th September 1917, the middle stripe was changed to blue to show solidarity with the Allies during the First World War.
