Assessing and Explaining the Diverging Trajectories of Territorial Parties and Politics in Italy and Spain (2008‐2018)

Until the mid‐2000s, territorial politics played a considerable role in both Italy and Spain. Two regionalist parties, among others, clearly contributed to this: Democratic Convergence of Catalonia (CDC) and the Northern League. Yet evidence shows that the two parties, while starting from relatively similar positions, have followed diverging trajectories, particularly after the financial (and then economic) crisis that hit their respective countries. CDC pushed its pro‐autonomy stances to the extreme and eventually ended up supporting Catalan independence. On the other hand, the League dropped its regionalist agenda and even became a state‐wide party. By comparing these two cases, this article aims to shed light on the mechanisms that lead to the radicalisation or moderation (and even abandonment) of regionalist parties’ territorial demands. These opposite movements have broader implications, since they have been accompanied by increasing polarisation of territorial politics in Spain and the de‐politicisation of this issue in Italy.
