After beeing part of the Danish autocracy for 400 years, Norway got its own constitution in 1814 and joined into a loose union with Sweden that lasted until 1905.
A limited and hereditary monarchy was introduced, whereby the king would exercise his authority through a government, while Parliament (Storting) would allocate monies and make laws. The Norwegian constitution was the most modern in Europe at the time.
Norwegians celebrate their national day differently than in any other country.
On 17 May, it is the colourful processions of children with their banners, flags and bands - not military parades - that play the main role. It is the spring celebration, from the lowliest backwater to the capital city of Oslo, where the Royal Family waves to the passing procession from the palace balcony.
Another special characteristic that contributes to making this a unique day is all the beautiful bunads or national costumes that more and more people are wearing in recent years. Foreigners especially seem to delight in experiencing this special occasion.
