Deindustrialization fosters ethnonationalism; a comparative analysis of ethnonational parties in Western Europe, 1918–2018


 This article demonstrates that deindustrialization increases ethnonational mobilization. We maintain that levels of mobilization of ethnonational movements are to an important extent a residual to the class cleavage, that is, to the degree the class conflict dominates political competition. Since in the context of Western Europe industrialism is the main force behind the class cleavage, deindustrialization weakens this cleavage and allows instead for mobilization along ethnonational divisions. In order to empirically test our argument, we analyze levels of electoral mobilization of ethnonational party blocs among 15 Western European minorities between 1918 and 2018. Our analysis clearly reveals that levels of industrialization are negatively related to ethnonational mobilization. However, this is only true for regions with historically high levels of industrialization and if the ethnonational movement is unified. The article contributes to the comparative literature on the electoral performance of ethnonational parties and the literature on deindustrialization and nationalism.
