Norway [?n??we?] (help·info) (Norwegian: Norge (bokmål) or Noreg (nynorsk)), officially the Kingdom of Norway, is a constitutional monarchy in Northern Europe that occupies the western portion of the Scandinavian Peninsula. It is bordered by Sweden, Finland, and Russia, while the United Kingdom and the Faroe Islands lie to its west across the North Sea. The country's extensive coastline, facing the North Atlantic Ocean, is home to its famous fjords. In the 1920s, Norway annexed Jan Mayen and was given the sovereignty over the Arctic archipelago of Svalbard under the Svalbard Treaty. The polar territories of Bouvet Island, Peter I Island and Queen Maud Land are external dependencies, but not parts of Norway.
