The cross motif first appears in Danish sources of the 13th century, and as Scandinavian power shifted (e.g. the Kalmar Union’s banner), each emerging Nordic nation adopted its own cross-flag.  For example, Sweden chose a yellow cross on blue (drawing on 15th-century arms) and codified its flag in 1906; Norway adopted a red-white-blue cross in 1821 upon independence; and Finland and Iceland introduced blue-cross flags after gaining autonomy in the early 20th century.

Nordic Country Flags

  • Denmark (Dannebrog): White cross on red.  According to tradition, the Dannebrog “fell from the sky” at the 1219 Battle of Lindanise. The Dannebrog is recorded as adopted on 15 June 1219 and holds the Guinness World Record as the oldest continuously used national flag (in uninterrupted use since 1625).
  • Sweden: Yellow cross on blue.  This design was inspired by Sweden’s royal coat of arms (1442).  Sweden’s blue-and-yellow colors date back to 13th-century royal arms, and the current flag design was legally established in 1906.
  • Norway: Red with a blue cross outlined in white.  Norway’s national flag, designed by Fredrik Meltzer, was adopted on 13 July 1821 after separation from Sweden.  Its colors combine Denmark’s red-and-white with Sweden’s blue (the white border was intended as a neutral outline).
  • Finland: White with a blue cross.  Known as the “Blue Cross Flag,” it was adopted on 28 May 1918 after Finnish independence.  The blue-and-white reflects Finland’s lakes and winter snow and underscores Finland’s ties to the other Nordic countries.
  • Iceland: Blue with a red cross outlined in white.  This flag (approved by Denmark in 1915 and fully adopted in 1918) uses the Danish red–white plus Iceland’s blue to show national identity and Nordic heritage.  (Its shade of blue was slightly changed in 1944 when the republic was founded.)
  • Faroe Islands (Merkið): White with a red cross outlined in blue.  Proposed in 1919, it was first raised 25 April 1940 (during British occupation, when Denmark was under German control) and formally recognized under Danish rule in 1948.
  • Åland Islands (Finland): Blue with a yellow cross outlined in red.  Adopted in 1954, this flag merges Swedish colours (yellow-blue) with a red cross to represent Finland – reflecting Åland’s Swedish-speaking culture under Finnish sovereignty.

Estonia’s Nordic Connection

Estonia’s story is a Nordic twist: Denmark’s flag legend happened on Estonian soil, yet Estonia’s own flag is a blue-black-white tricolor (not a Nordic cross). Estonia adopted the tricolor on 21 Nov 1918 to symbolize its new independence.  Nonetheless, many Estonians identify culturally with the Nordics: Estonian is a Finnic language closely related to Finnish, and Sweden had a presence in coastal Estonia since the 13th century. In fact, a Nordic-cross design was even proposed for Estonia in 1919 (though the tricolor prevailed), highlighting this unique Nordic–Baltic blend of influences.
