Norway and Sweden sign the "Karlstad treaty", peacefully dissolving the Union between the two countries.

The dissolution of the union (Bokml: Unionsopplsningen; Nynorsk: Unionsopplysinga; Landsml: Unionsopplysingi; Swedish: Unionsupplsningen) 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 (then in personal union) 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.

Karlstad (US: , Swedish: [ˈkɑ̌ːɭsta(d)] (listen)) is a city, the seat of Karlstad Municipality, the capital of Värmland County, and the largest city in the province Värmland in Sweden. The city had 65,856 inhabitants in 2020 with 95,167 inhabitants in the wider municipality in 2021 [1], and is the 21st biggest municipality in Sweden. Karlstad has a university and a cathedral.

Karlstad is built on the river delta where Sweden's longest river, Klarälven, runs into Sweden's largest lake, Vänern. It has the second largest lake port in the country after Västerås.

Karlstad is often associated with sunshine and the symbol for Karlstad is a smiling sun. Karlstad is reputed to be one of the sunniest towns in Sweden and a local waitress, known as "Sola i Karlstad" (the Sun in Karlstad) for her sunny disposition, is also commemorated with a statue.
