From 65438 to 0905, the alliance between Sweden and Norway disintegrated, Norway gained independence, and the realism tradition in literature was restored and developed. In drama, there are proletarian writers such as Grieg (1902~ 1943) and Nelson (1901929), whose works reflect the life and revolutionary struggle of workers. Krogh (1889~ 1962) inherited the psychoanalytic skills of Ibsen and Heiberg, while Grieg followed the tradition of Beyonce's action drama. At this time, novel creation also took on a new look, with works exposing capitalist exploitation and reflecting workers' struggle. Among them, Falkberget (1879 ~1967) and Uppdal (1878 ~1961) are famous novels describing the struggle life of miners and construction workers.
Under the influence of Russian October Revolution, some radical intellectuals founded Dawn magazine, so they were called "Dawn School", and the main representatives were young writers Overland, Hull and Clough. They had a heated debate with liberal conservatives and religious writers represented by Fang En. Their political views are different, but their creation is mainly psychological description. There are two schools of novel creation in this period, namely "local literature" school and "psychological literature" school. The outstanding work is the historical novel Christine loveland's Daughter by Undset (1920~ 1922).
During the German fascist occupation of Norway and some time after the war, many anti-fascist works appeared, such as Nansen's Day After Day and Diary of the Moon. In terms of novels, Evans Moore's narrative work Adventures on a Westward Journey has a great influence. Other writers, such as Heiberg, Ben Hansen, Viisas and Huff Ribble, have also written many works in this field. O 'Fran, Grieg, Les Anderson and Hargrup, etc. , contributed to the struggle for freedom. Viisas's novel Germination (1940) and other postwar works combine symbolism with realism, giving Norwegian novels new features. The short stories of Borgen, Luther, Netrios, Micheler and Christopher are also innovative in their forms of expression. The post-war poetry creation generally followed the traditional poetry language.
In 1950s, Hoffmore, Blake and Buweiler continued to inherit and develop realism. In the 1960s, a group of talented young writers emerged, such as Solsta, Ubud Resta and Zhan Sen. At the end of 1960s, "Documentary Doctrine" appeared, which marked the new development of Norwegian literature.
