Svalbard Act in the context of "Demilitarized zone"

Svalbard (/ˈsvɑːlbɑːr(d)/ SVAHL-bar(d), Urban East Norwegian: [ˈsvɑ̂ːɫbɑr]) — formerly Spitsbergen or Spitzbergen — is a Norwegian archipelago that lies at the convergence of the Arctic Ocean with the Atlantic Ocean. North of mainland Europe, it lies about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen (37,673 km), followed in size by Nordaustlandet (14,443 km), Edgeøya (5,073 km), and Barentsøya (1,288 km). Bjørnøya or Bear Island (178 km) is the most southerly island in the territory, situated some 147 km south of Spitsbergen. Other small islands in the group include Hopen to the southeast of Edgeøya, Kongsøya and Svenskøya in the east, and Kvitøya to the northeast. The largest settlement is Longyearbyen, situated in Isfjorden on the west coast of Spitsbergen.

Whalers who sailed far north in the 17th and 18th centuries used the islands as a base; subsequently, the archipelago was abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities such as Pyramiden and Barentsburg were established. The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, and the Norwegian Svalbard Act of 1925 made Svalbard a full part of the Kingdom of Norway. The Svalbard Treaty established Svalbard as a free economic zone and restricts the military use of the archipelago. The Norwegian Store Norske and the Russian Arktikugol remain the only mining companies in place.
