The Constitution of Denmark was signed on 5 June 1849, ending the absolute monarchy which had begun in 1660.It establishes a constitutional monarchy organised as a parliamentary democracy.This is centred primarily on the prefix "Dan" and whether it refers to the Dani or a historical person Dan and the exact meaning of the -"mark" ending.
It is believed that Denmark became Christian for political reasons so as not to get invaded by the rising Christian power in Europe, the Holy Roman Empire, which was an important trading area for the Danes.In that case, Harald built six fortresses around Denmark called Trelleborg and built a further Danevirke.Under the reign of Gudfred in 804 the Danish kingdom may have included all the lands of Jutland, Scania and the Danish islands, excluding Bornholm.As attested by the Jelling stones, the Danes were Christianised around 965 by Harald Bluetooth, the son of Gorm.In the 19th century there was a surge of nationalist movements, which were defeated in the 1864 Second Schleswig War. In April 1940, a German invasion saw brief military skirmishes while the Danish resistance movement was active from 1943 until the German surrender in May 1945.
An industrialised exporter of agricultural produce in the second half of the 19th century, Denmark introduced social and labour-market reforms in the early 20th century that created the basis for the present welfare state model with a highly developed mixed economy.From the 8th to the 10th century the wider Scandinavian region was the source of Vikings.They colonised, raided, and traded in all parts of Europe. The islands are characterised by flat, arable land and sandy coasts, low elevation and a temperate climate.The unified kingdom of Denmark emerged in the 10th century as a proficient seafaring nation in the struggle for control of the Baltic Sea.In the early 11th century, Canute the Great won and united Denmark, England, and Norway for almost 30 years with a Scandinavian army.
