Dependencies ceded to Denmark (3rd phase)
Faroe Islands, settled and colonized pre-1035 and crown dependencies from 1035 to 1814, ceded by the Treaty of Kiel.
Greenland, colonized pre-1261 and crown dependency from 1261 to 1814, ceded by the Treaty of Kiel.
Iceland, settled and colonized pre-1262 and crown dependencies from 1262 to 1814, ceded by the Treaty of Kiel.
The actual time of cession of the islands is somewhat disputed. Some claim it took place with the Union of Denmark and Norway in 1536/37, as the possessions of the Norwegian crown were claimed by the Oldenburg king. Nevertheless, they were still referred to as "dependencies of Norway" in later official documents. Also the Treaty of Kiel states: "...and provinces, constituting the kingdom of Norway, , together with their dependencies ; shall belong in full and sovereign property to the King of Sweden,...", clearly indicating that they were until 1814 regarded as a part of Norway.
Sverdrup Islands, now part of Canada, claimed from 1902 until Canadian sovereignty recognised in 1930, as part of an agreement with the British Empire, for the British to recognise Jan Mayen as Norwegian territory.
Erik the Red's Land, northeast coast of Greenland, claimed and annexed from 1931 until awarded to Denmark by a court decision in 1933.
Murmansk and Arkhangelsk as Bjarmland, now part of Russia, claimed from the Soviet Union from about 1942 to 1945 by the Quisling regime, and was earlier also claimed by Norway in the High Middle Ages and Late Middle Ages. Quisling designated the area reserved for Norwegian colonization as Bjarmeland, a reference to the name featured in the Norse sagas for Northern Russia.
