How quickly a liberal and politically neutral country such as Norway can be deprived of its freedom (e.g. of expression) is illustrated by the censorship imposed by the Nazi regime.
Shortly after the occupation of Norway in World War II, the press department of the Reich Commissariat controlled the entire public media. The sale, purchase or lending of hundreds of books was prohibited with immediate effect. The first book to be hit by National Socialist censorship in April 1940 was “Hitler har sagt det” (in German: “Hitler hat es gesagt“) by Hermann Rauschning.
