Twenty-five years of Norwegian sovereignty in Svalbard, 1925–50

By a treaty signed in Paris on 9 February 1920, Norway was given the sovereignty of Svalbard, comprising all the islands situated between longs. 10° and 35° E. and lats. 74° and 81° N., thus including Spitsbergen, Bjørnøya (Bear Island), Hopen (Hope Island), Kong Karls Land, and Kvitøya (White Island). The treaty, which has since been recognized by a number of other states, was signed by the United States of America, Denmark, France, Italy, Japan, the Netherlands, Great Britain and Ireland, the Dominions of Canada and New Zealand, the Union of South Africa, India, and Sweden. The U.S.S.R. recognized Norway's sovereignty of Svalbard in 1924 but did not sign the treaty until 1935; Germany signed the treaty in 1925. On 14 August 1925, Norway formally took possession and the Norwegian flag was hoisted in Longyearbyen. Since then, twenty-five years have elapsed, and in honour of the occasion the anniversary was celebrated at Longyearbyen in 1950.
