17th century in Denmark

Denmark–Norway was a 16th-to-19th-century multi-national and multi-lingual real union consisting of the Kingdom of Denmark, the Kingdom of Norway (including the then Norwegian overseas possessions: the Faroe Islands, Iceland, Greenland, and other possessions), the Duchy of Schleswig, and the Duchy of Holstein. The state also claimed sovereignty over three historical peoples: Frisians, Gutes and Wends. Denmark–Norway had several colonies, namely the Danish Gold Coast, Danish India (the Nicobar Islands, Serampore, Tharangambadi), and the Danish West Indies.
