The 17th of May is a sacred day for many Norwegians. It is the day of the Norwegian constitution, which heroically even more sacred, since it remarks the independence from the Swedish kingdom, and then from the Danish kingdom, and back again to the Swedes (the Danish and the Swedish kingdoms were constantly in war back then; and when the Danes chose a wrong guy, a.k.a Napoleon, in one of the wars, they had to hand over Norway, in tears, to their viking brother across the Øresund channel – the Swedes).
The Norwegian constitution (May 17, 1814) is an inspiration for the danish constitution (June 5, 1849). In Denmark, the constitution also remarks the end of the absolute monarchy in the country. However, because Denmark had been for ages being a wealthy powerful kingdom, the constitution has merely been seen as an noble moment at the parliament by many danes; it does not carry the same emotional degree as the constitution in Norway, which seen by many as a symbol of freedom and sovereignty. That is why the norwegians around the world dedicate the 17th of may as a holiday to celebrate, throw party, dress in bunad (norwegian traditional dress), parade along the street while waving the norwegian flag, and enjoy massive amounts of beers and foods (including the classic pølse og lompe: a grill sausage, wrap in oat bread & soft ice). On the contrary, the celebration scene like this is hardly found during the constitutional day in Denmark.
