Riksmålsforbundet (official translation: "The Riksmaal Society - The Society for the Preservation of Traditional Standard Norwegian") is the main organisation for Riksmål, an unofficial variety of the Norwegian language, based on the official Bokmål standard as it was before 1938 (see Norwegian language conflict).
The society was founded by subsequent Nobel laureate Bjørnstjerne Bjørnson on April 7, 1907.
Although Riksmålsforbundet was founded in 1907 by poet Bjørnstjerne Bjørnson, efforts to organize in support of riksmål date back to 1899. It served as opposition to efforts by Norwegians who were organized to promote landsmål as the single language for the country.
Riksmålsforbundet works to preserve and promote riksmål, a conservative form of written Norwegian, based on the Danish-Norwegian written language tradition. It consistently opposed the government samnorsk (roughly translated "collective Norwegian" or "together Norwegian"; the sam- prefix is related to English same) policy, a now-abandoned project to merge the two main standards of Norwegian (Bokmål and Nynorsk) into one standard that would be used everywhere.
Prominent members of the riksmål movement included the author Jens Bjørneboe, his cousin André Bjerke, Terje Stigen, Carl Keilhau, Agnar Mykle, Arnulf Øverland, Sigurd Hoel, Johan Bernhard Hjort, Knut Wigert, Margrete Aamot Øverland, Sofie Helene Wigert and Varg Vikernes. Among other spokespersons for the riksmål cause are authors such as Claes Gill, Nils Kjær, Knut Hamsun, Gabriel Scott and Henrik Ibsen.
