Svalbard is a Norwegian archipelago in the Arctic Ocean, situated north of mainland Europe. Its location is roughly midway between Norway's northern coast and the North Pole. The archipelago includes islands ranging from 74° to 81° north latitude and 10° to 35° east longitude. Major islands include Spitsbergen, Nordaustlandet, Edgeøya, and Barentsøya. Bear Island (Bjørnøya) sits furthest south, approximately 147 km from Spitsbergen. Other minor islands include Hopen, Kongsøya, Svenskøya, and Kvitøya. The largest settlement in Svalbard is Longyearbyen, located on Spitsbergen's west coast within Isfjorden.
By 1904, British interests established themselves in Adventfjorden and started the first year-round mining operations.
In 1907, Gunnar Isachsen revived Baltazar Keilhau's theory that the Old Norse toponym Svalbarði referred to Spitsbergen, to help modern Norway's claim to sovereignty.
