Modernism appeared on a broad front in the Norwegian poetry of the 1950s. It impacted the lyrics produced by Tarjei Vesaas, Ernst Orvil, Astrid Tollefsen and Olav H. Hauge. Among the younger poets, such as Astrid Hjertenæs Andersen, Paal Brekke, Hans Børli, Harald Sverdrup and Marie Takvam, free verse was the preferred form. Paal Brekke was modernism's foremost advocate against traditionalists – such as Arnulf Øverland and André Bjerke – in a wide-ranging debate about poetic forms which is recognized as the "speaking-in-tongues debate". Georg Johannesen's first publication "Dikt" (Poetry) in 1959 introduced a new interest in political and social values, that had not been particularly evident in the 1950s. At the same time, the well-established poet, Rolf Jacobsen, espoused a more critical attitude to the consumer mentality and environmental destruction.
