In Galicia, translation slowly emerged as part of a cultural program during the 1920s, primarily through the activities of the Xeración Nós and the Irmandades da Fala, two intellectual and political groups seeking to recuperate and defend Galician language and culture through two magazines, A Nosa Terra and Nós. This aspect of nationalism is deserving of study because few scholars have addressed how the appropriation of literary texts, via translations, impacts nationalists' agendas. Nineteenth-century Galician scholars had claimed to establish ethnic and cultural links in early history between Galicia and Ireland and other alleged Celtic nations. The Xeración Nós and the Irmandades da Fala continued this legacy by researching Celtic and Irish history as well as introducing Irish writers, discussing their contributions to literature, and translating their works in journals. Their main intention was to demonstrate the Galicians' distinctiveness from Spain and to establish a common link with a nation struggling for its national rights. Therefore, for both journals, the subject of Ireland and the Irish was an obligatory and ideologically imperative reference. This thesis examines the role of translation in Nos and A Nosa Terra and its impact on Galician cultural nationalism. Working within the parameters of translation theory, nationalism, and post-colonialism, I consider why literary works by authors such as W.B. Yeats (1865-1939), James Joyce (1882-1941), and Terence MacSwiney (1879-1920), and the Irish epic, Leabhar Gabhála (The Book of the Conquests of Ireland), are discussed and later translated into Galician and what these translations seek to achieve within the re-emerging culture. On this basis, my objective is to show that as translated literature assumes a new role by providing invigorating models in the target culture, it regenerates national culture, language, and literature.
