Every year on 17 May, Norway becomes a sea of red, white and blue. Flags fly from houses, balconies and public buildings, while thousands of children wave smaller versions as they parade through towns and cities.
For many Norwegians, the flag is a strong national symbol. The flag is a celebration of independence, identity and the country's long journey towards becoming a nation in its own right.
Yet the familiar Norwegian flag has a more complicated history than you might expect.
Although its design dates back to 1821, Norway didn't achieve full independence until 1905. In between, the flag became the subject of political arguments, royal disagreements and even a controversy involving something nicknamed the herring salad.
So, how did Norway end up with its distinctive red, white and blue flag? And what do its colours actually mean?
What Does the Norwegian Flag Look Like?
The Norwegian flag consists of a red background with a dark blue cross outlined in white. The vertical section of the cross is positioned closer to the flagpole rather than in the centre.
This is known as a Nordic cross, a design shared by several neighbouring countries, including Denmark, Sweden, Finland and Iceland.
The design is simple, but its colours and arrangement tell a story about Norway's history and its relationship with the rest of Scandinavia.
The flag's proportions are also carefully defined. The standard rectangular national flag has a height-to-length ratio of 16:22.
What Do the Colours of Norway's Flag Mean?
The red, white and blue colours were deliberately chosen in 1821. At the time, these colours were associated with freedom and independence, thanks partly to their use in the flags of revolutionary France and the United States.
But they also reflected Norway's complicated political relationships.
The red background and white cross maintained a connection with Denmark, which had ruled Norway for centuries. The addition of blue acknowledged Sweden, Norway's new partner in a political union.
The result was a flag that recognised Norway's past while expressing hope for a more independent future.
You'll sometimes see other interpretations of the colours. Red might represent courage, white the snow-covered landscape, and blue the surrounding sea. While these associations are appealing, they weren't the original explanation behind the design.
The Earliest Norwegian Flag: A Golden Lion
Long before the familiar Nordic cross appeared, Norway used a very different symbol: a golden lion holding an axe against a red background.
The lion has been associated with Norwegian royalty since the Middle Ages and remains central to Norway's coat of arms.
One of the earliest known representations of a Norwegian flag appears on a seal belonging to Duchess Ingebjørg Håkonsdatter from 1318.
The seal depicts a banner featuring the Norwegian royal lion. This was a royal symbol rather than a national flag in the modern sense, although variations were later used on ships and fortifications.
The lion itself dates back further, becoming established as a royal emblem during the 13th century. It's a remarkable piece of continuity. More than 700 years later, the golden lion still appears on Norway's royal flag.
Norway's Flag During Danish Rule
For centuries, Norway didn't have the political independence to determine its own national symbols.
In 1380, Norway and Denmark came under the same monarch. Both kingdoms subsequently became part of the Kalmar Union, which also included Sweden, beginning in 1397.
Although Sweden eventually left the union, Norway remained closely tied to Denmark until 1814. During this long period, the Danish flag, known as the Dannebrog, became increasingly common in Norway.
Its simple red background and white Nordic cross would eventually provide the foundation for the modern Norwegian flag.
By 1748, the Dannebrog was the only officially recognised merchant flag for the combined Danish-Norwegian state. The Danish connection came to an end in dramatic circumstances in 1814.
The First Norwegian Flag After Denmark
The Napoleonic Wars transformed the political map of Europe, including Scandinavia. Denmark-Norway had been on the losing side, and under the Treaty of Kiel in January 1814, the Danish king agreed to cede Norway to the Swedish king.
However, Norwegians had other ideas. Rather than simply accept Swedish rule, representatives gathered at Eidsvoll and adopted a constitution on 17 May 1814. Christian Frederik was elected king of an independent Norway.
The newly independent country also needed a flag. A simple solution was adopted: the familiar Danish flag, but with the Norwegian golden lion added to the upper corner closest to the flagpole. This was Norway's first distinctive national flag of the modern era.
Independence proved short-lived. Following a brief war with Sweden, Norway entered a new union under the Swedish monarchy later that year, although it retained its constitution and parliament.
The question of which flag should represent Norway remained unresolved. In 1818, King Carl Johan introduced a common merchant flag for the two kingdoms, based primarily on the Swedish design. For many Norwegians, it was far from a satisfactory solution.
The Birth of Today's Norwegian Flag in 1821
By the early 1820s, demands for a recognisably Norwegian flag were growing, particularly among merchants and shipowners.
For a country with such a strong maritime tradition, the issue mattered. Merchant vessels needed flags that identified them internationally, but the question was also becoming one of national dignity.
In 1821, the Norwegian parliament considered 18 competing flag designs. The winning proposal came from Fredrik Meltzer, a businessman and parliamentary representative from Bergen.
His idea combined the existing Danish red and white design with a blue cross, creating the flag we recognise today.
Meltzer argued that red, white and blue were the colours of freedom. The design also retained the familiar Nordic cross and offered a compromise between Norway's Danish past and Swedish present.
On 4 May 1821, parliament selected Meltzer's proposal by 40 votes to 19.
However, the Swedish-Norwegian king, Carl Johan, objected to the parliament's authority to determine the flag. He declined to formally approve the legislation, instead authorising the design as Norway's merchant flag by royal decree on 13 July 1821.
There was another complication. Initially, the new Norwegian flag could only be used by merchant ships in certain northern European waters. Ships travelling farther afield had to use an internationally recognised Swedish or union flag. These restrictions were lifted in 1838.
Norway finally had a distinctive flag, but it was not yet the only flag representing the country.
The Norwegian Flag's Strange ‘Herring Salad' Era
One of the most unusual chapters in Norwegian flag history began in 1844. Under King Oscar I, Norway and Sweden introduced new union flags intended to demonstrate the equality of the two kingdoms.
Both countries retained their national flag designs, but a combined union emblem was placed in the upper corner. This emblem incorporated elements of the Norwegian and Swedish flags, creating a colourful geometric pattern.
It soon acquired an unforgettable nickname: sildesalaten, meaning the ‘herring salad'. The name referred to the busy mixture of colours and shapes, which some thought resembled a Scandinavian herring salad.
Although it might appear strange today, the design was initially welcomed by many Norwegians. Unlike earlier union flags dominated by Swedish symbols, this one gave the two kingdoms equal representation.
But attitudes changed as Norwegian nationalism grew throughout the second half of the 19th century.
Increasingly, the union emblem was seen not as a symbol of equality, but as an unwelcome reminder of foreign control.
The demand for the return of the pure Norwegian flag, without the herring salad, became an important political cause.
The Fight for the ‘Pure Norwegian Flag'
By the late 1800s, the flag had become much more than a question of design. It was a visible expression of the growing desire for Norwegian self-government.
Among those campaigning for the removal of the union emblem was writer and national icon Bjørnstjerne Bjørnson.
The issue also divided public opinion. Some sailors and commercial interests opposed the changes, while supporters of greater independence wanted Norwegian ships to sail under an unmistakably Norwegian flag.
The dispute eventually reached a turning point in 1898. After repeated attempts, the Norwegian parliament passed a law establishing the flag without the union emblem as the country's merchant flag.
King Oscar II refused to sanction the legislation, but under Norway's constitution, parliament's repeated approval meant that it could become law without royal assent.
The legislation took effect on 15 December 1899. Celebrations included torchlight processions in Kristiania, now Oslo, and Trondhjem, now Trondheim.
The pure Norwegian flag could once again be used officially in civilian contexts, including on merchant ships. However, the union emblem remained on Norway's naval flag. That would change just a few years later.
Independence in 1905: The Norwegian Flag Finally Stands Alone
On 7 June 1905, the Norwegian parliament declared that the union with Sweden had been dissolved. It was the culmination of decades of increasing tensions over Norway's political independence.
Two days later, on 9 June, the Norwegian flag without the union emblem was raised at Akershus Fortress in Kristiania.
The removal of the emblem from the naval flag brought the country's various flags into line with its new political reality.
For the first time, Norway's familiar red, white and blue design could represent a fully independent Norwegian state. The flag itself had changed remarkably little since 1821. What had changed was the country flying it.
The Norwegian Flag Today
More than a century after independence, the Norwegian flag remains one of the country's most recognisable national symbols. Its greatest moment comes every year on 17 May, Norway's Constitution Day.
Unlike many national celebrations elsewhere in the world, Norway's national day focuses heavily on children and community events rather than military parades.
Children carry flags through the streets, homes are decorated in red, white and blue, and town centres fill with people celebrating.
The tradition has historical roots. Bjørnstjerne Bjørnson helped organise a children's flag parade in Kristiania in 1870, strengthening the connection between the Norwegian flag and the national day.
But 17 May is far from the only occasion when you'll see Norwegian flags flying. Norway has several official flag days, when state institutions are required to fly the flag.
Private households are not generally required to follow the official flagging rules, but many Norwegians choose to display flags on national holidays, birthdays and family celebrations.
On Sámi National Day, the colourful Sámi flag is also widely displayed, recognising the Indigenous Sámi people and their culture across northern Europe.
Why Does Norway's Flag Have a Nordic Cross?
Norway's flag belongs to a wider family of Nordic cross flags.
The design originated with Denmark's Dannebrog and subsequently influenced the national flags of Sweden, Norway, Finland and Iceland. The Faroe Islands and Åland Islands also use variations of the Nordic cross.
Historically, the cross reflected Christianity's important role in the Nordic countries. Its distinctive off-centre positioning has become a defining feature of Scandinavian flag design.
Norway's version stands out because of its combination of three colours, rather than the two used in the Danish and Swedish flags.
The Norwegian flag may look simple today, but its history is anything but. From medieval royalty to competing Scandinavian unions and the struggle for independence, the red, white and blue design has witnessed some of the most important moments in Norway's history.
And perhaps that's why the sight of thousands of Norwegian flags waving on 17 May remains such a powerful one.
