Denmark–Norway

Also known as Denmark-Norway

When the Kalmar Union fell apart after Sweden broke away in 1523, Denmark kept Norway, and in 1537 Christian III made Norway a dependency ruled from Copenhagen, along with Iceland, the Faroe Islands and claims to Greenland. The twin realms controlled the Sound, the narrow strait into the Baltic, and collected rich tolls from passing ships.

Christian IV built towns and fortresses but lost wars to Sweden, and in 1658 Denmark gave up Scania, Halland and Blekinge for good. In 1660 Frederick III became an absolute hereditary monarch. Denmark-Norway also held trading posts in India and on the Gold Coast, and the Danish West Indies, where enslaved Africans grew sugar. Siding with Napoleon proved disastrous: after his defeat, the Treaty of Kiel in 1814 handed Norway to Sweden.
