The Kingdom of Denmark, commonly known as Denmark, is a nation situated in Scandinavia in northern Europe. It is the southernmost of the Nordic countries. The mainland is bordered to the south by Germany; Denmark is located to the southwest of Sweden and the south of Norway. Denmark borders both the Baltic and the North Sea. The country consists of a large peninsula, Jutland and a large number of islands. Denmark has long controlled the approach to the Baltic Sea, and these waters are also known as the Danish straits. The Faroe Islands and Greenland are autonomous provinces of Denmark with home rule.

Denmark remained its neutrality in World War I and was invaded by Germany in 1940. Economic co-operation between Germany and Denmark continued until 1943, when the Danish government refused further co-operation and the Navy sank most of the Danish fleet and sent as many of their officers as they could to Sweden. During the war, the government was extremely helpful towards Jews living in the country, and the resistance managed to get most of the Jews to Sweden and safety. After the war, Denmark became one of the founding members of the United Nations and NATO and in 1973, along with Britain and Ireland, joined the European Economic Community (now the European Union) after a public referendum.
