Politics and the nation: nationalist mobilisation of ethnic differences

. Based on a critique of the exogenous and expressive views of politics underlying many studies of nationalism, this article analyses the political factors that affect nation‐building processes in a direct manner. First, ethnicity should be considered not so much as an historical and objective starting point but as the outcome of nationalist intellectuals' efforts at filtering and selecting political and cultural elements. It is important to examine the structure and genealogy of nationalist ideological capital using myth/symbol analysis or frame analysis. Second, one of the key concepts in the study of nationalist movements is the Political Opportunity Structure, as it refers to the developmental context, both institutional (democratisation, decentralisation, etc.) and strategic (potential allies, electoral dealignments, etc.). In this sense, ethnic regulation policies should not be taken as mere effects or responses, but as decisive intervening causes in the very process of national identity‐building. Finally, this article argues that rational choice analysis and collective action logic can be found useful in explaining the successes or failures of nationalist movements that attempt to mobilise and organise politically as mass phenomena.
