The oldest national flag in the world still in use.
According to legend, the flag came into Danish possession during the Battle of Lyndanisse in 1219. The Danes were on a failing crusade in Estonia, but after praying to God a flag fell from the sky. After this event, Danish King Valdemar II went on to defeat the Estonians.
