スウェーデン＝ノルウェー
The entire Svalbard archipelago, nominally ruled first by Denmark–Norway, and later the Norwegians (as Union between Sweden and Norway from 1814 to 1905, independent Norway from 1905), remained a source of riches for fishery and whaling vessels from many nations. The islands also became the launching point for a number of Arctic explorers, including William Edward Parry, Adolf Erik Nordenskiöld, Otto Martin Torell, Alfred Gabriel Nathorst, Roald Amundsen, and Ernest Shackleton.
