The Dannebrog, known as the flag of Denmark, features a red background with a white cross extending to the edges. The cross, called the Scandinavian Cross or Nordic Cross, centers on the flag. The vertical part of the cross shifts towards the hoist side of the flag.

The origin of the Dannebrog is based on a legendary tale of a battle fought in Estonia in 1219. During the battle, a white cross fell from the sky, giving the Danish soldiers strength to win. Since then, the flag has become an important national symbol of Denmark. Since the 14th century, people have used variations of the flag.
