The national flag of Denmark is called Dannebrog. The Denmark flag is red with a white cross that extends to the edges of the flag shifted to the left side.
The Denmark flag is the oldest state flag in the world still in use, with the earliest source dating back to the 14th century. Prior to the use of Dannebrog, Denmark used the raven banner.
The Denmark flag that is officially used by the Danish royalty was introduced on 16 November 1972 when the Queen adopted a new version of her personal coat of arms. The royal standard is the Denmark flag with a swallow-tail and charged with the monarch’s coat of arms set in a white square.
