At the same time, literary texts themselves sometimes have a tendency to resist cultural narratives and stereotypical ideas of a certain nation. This article explores how such a resistance is made in the English translations of four Swedish novels from the 1930s. These novels are all central texts in the history of Swedish literature, as they form the very basis of a literary current that had a huge impact on the development of the Swedish welfare state--proletarian fiction. In the translations of Harry Martinson's, Moa Martinson's, Eyvind Johnson's, and Ivar Lo-Johansson's breakthrough novels, the Anglophone target reader is faced with different kinds of disruptions of the Swedish national identity. Some of these disturb the conception of Sweden as a unified cultural space; others resist the idea of Sweden as a distinct cultural space. There is, however, no general rule to these disruptions: All four novels have their own, specific way of creating narrative resistance.展开更多
