In the 1938 reform of Bokmål introduced more elements from dialects and Nynorsk, and more importantly, many traditional Dano-Norwegian forms were excluded. This so-called radical Bokmål or Samnorsk (no) (Common Norwegian) met even stiffer resistance from the Riksmål movement, culminating in the 1950s under the leadership of Arnulf Øverland. Riksmålsforbundet organised a parents' campaign against Samnorsk in 1951, and the Norwegian Academy for Language and Literature was founded in 1953.
