Key Details of the Danish Flag (Dannebrog)
- Country: Denmark
- Design: White Scandinavian cross on a red background
- Date of Continuous Use: Dating back to 1625
This longevity makes the Danish flag a unique symbol of national identity and history, unmatched in continuous use by any other nation's flag. While the design of the flag is sometimes traced further back in legend (often to 1219), the record for continuous official use solidifies its claim as the oldest.
Understanding what "continuously-used" means is important in this context. It signifies that the design has remained unchanged and has been officially recognized and used as the national flag without significant interruption over centuries, distinguishing it from older designs that may have been retired or altered before later reinstatement.
