Choose your target wisely: how the EU shapes nationalism in contemporary Europe.

Nationalism has experienced a resurgence across Europe since 1980, and one common explanation for this resurgence is that the backlash to European integration aids radical right parties, which prioritise cultural protectionism in the form of anti-immigration and anti-ethnic minority appeals. In contrast, this article argues that, through the policy-making avenues available to certain parties, but not others, European integration encourages a different form of nationalism in highly regionalised countries: ethnoregionalism, which seeks either greater autonomy or independence for a sub-national unit. By examining how nationalist parties combine both cultural protectionism and ethnoregionalism, and the relative saliency that they attach to each, this article provides a novel way to disentangle the EU's different potential effects on nationalism. Through a quantitative analysis of party manifestos across 33 European countries for 1980–2019, this article finds that European integration has a significantly stronger effect on the saliency of ethnoregionalism than cultural protectionism.
