Norway's core territory comprises the western and northernmost portion of the Scandinavian Peninsula; the remote island of Jan Mayen and the archipelago of Svalbard are also part of the Kingdom of Norway. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the Kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land. From the Middle Ages to 1814 Norway was part of the Danish kingdom. Norwegian possessions in the North Atlantic, Faroe Islands, Greenland, and Iceland, remained Danish when Norway was passed to Sweden at the Treaty of Kiel. Norway also comprised Bohuslän until 1658, Jämtland and Härjedalen until 1645, Shetland and Orkney until 1468, and the Hebrides and Isle of Man until the Treaty of Perth in 1266.
