The dissolution of the union between the kingdoms of Norway and Sweden under the House of Bernadotte, was set in motion by a resolution of the Storting on 7 June 1905. Following some months of tension and fear of an outbreak of war between the neighbouring kingdoms – and a Norwegian plebiscite held on 13 August which overwhelmingly backed dissolution – negotiations between the two governments led to Sweden's recognition of Norway as an independent constitutional monarchy on 26 October 1905. On that date, King Oscar II renounced his claim to the Norwegian throne, effectively dissolving the United Kingdoms of Sweden and Norway, and this event was swiftly followed, on 18 November, by the accession to the Norwegian throne of Prince Carl of Denmark, taking the name of Haakon VII.

The House of Bernadotte is the royal family of Sweden, founded there in 1818 by King Charles XIV John of Sweden. It was also the royal family of Norway between 1818 and 1905. Its founder was born in Pau in southern France as Jean Bernadotte. Bernadotte, who had been made a General of Division and Minister of War for his service in the French Army during the French Revolution, and Marshal of the French Empire and Prince of Ponte Corvo under Napoleon, was adopted by the elderly King Charles XIII of Sweden, who had no other heir and whose Holstein-Gottorp branch of the House of Oldenburg thus was soon to be extinct on the Swedish throne. The current king of Sweden, Carl XVI Gustaf, is a direct descendant of Charles XIV John.
