This paper examines the inner debate in Basque nationalism resulting from the Easter Rising between 1916 and 1918. Basque nationalists firmly believed that the Irish Revolution would affect the British war effort, the outcome of the Great War and hence Basque political vindication itself. The official nationalist leadership and its organ, Euzkadi, supported Great Britain, arguing a British military triumph in Ireland and in the Great War would bring a worldwide era of autonomy for national minorities. Pro-independence militants, however, not only expressed solidarity and outspoken support towards the rebels, but also associated their victory with a post-war scenario favourable to independence movements. This study focuses on the two competing Basque nationalist interpretations as presented in the media. Simultaneously, traditionalist parties (i.e. Carlists and Integrists) exacerbated nationalists’ differences in order to weaken a direct political rival. [ABSTRACT FROM AUTHOR]
