Domino effect or internal developments? The influences of international events and political ideologies on Catalan and Basque nationalism

Although comparative studies of nationalism have recently experienced a resurgence, few attempts have been made to analyse the reciprocal influences exerted upon one another by nationalist movements. This article distinguishes between a domino effect which denotes a concrete change at the governmental level, and a demonstration effect which signifies more general influences on nationalist movements exerted by ‘external’ models. A comparative analysis of external ideological influences on Basque and Catalan nationalism reveals that the domino effect metaphor does not easily apply to nationalism, while demonstration effects are often confined to certain sectors of these nationalist movements, generally the most radical ones.
