Like any other country Norway also celebrates their Independence Day on the day it became free from foreign invasion. The Norwegians got their independence after being under the Danish rule for some 400 years on 17th of May 1814. Norway had her own very peaceful revolution in 1814, which consisted of calling a constitutional convention declaring Norway a free kingdom, and thus the Independence Day of Norway came along.
On this day the Kingdom of Norway's constitution was signed by the national assembly at Eidsvoll, making Norway a free and independent nation. The Norwegian constitution was the most modern in Europe at the time. This Constitution day is still the most widely celebrated events in the nation, but is done differently from that of other nations.
