The Flag of Denmark

Among the independent nations recognized by the UN, the Danish flag is generally considered as the oldest continuously used national flag in existence, and thus fitting for my first post here.  Referred to in Danish as Danneborg, it is one of the most visually striking flags, and one of my personal favorites.  This flag falls under the Nordic Cross flag family, which all share a similar design, but different dimensions.  

There is a legend as to how this flag came to be. 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. The first recorded uses of the flag appear some one hundred years later.

Whether from divine sources or not, this flag is quite beautiful.
