Adomainname – Denmark is a Nordic country in Northern Europe, located southwest of Sweden and south of Norway, and bordered to the south by Germany. The Kingdom of Denmark comprises Denmark and two autonomous constituent countries in the North Atlantic Ocean, the Faroe Islands and Greenland. At 43,094 square kilometres (16,639 sq mi), with a population of around 5.6 million inhabitants, Denmark consists of a peninsula, Jutland, and the Danish archipelago of 407 islands, of which around 70 are inhabited. The islands are characterised by flat, arable land and sandy coasts, low elevation and a temperate climate. A Scandinavian nation, Denmark shares strong cultural and historic ties with its neighbours Sweden and Norway. The national language, Danish, is very closely related and mutually intelligible with Swedish and Norwegian. The unified kingdom of Denmark emerged in the 10th century as a proficient seafaring nation in the struggle for control of the Baltic Sea. Danish rule over the personal Kalmar Union, established in 1397, ended with Swedish secession in 1523.
