ABSTRACT
This article examines the determinants of the positioning of parties on the question of territorial reform in Belgium. It argues that one cannot explain the high salience assigned to the issue of decentralisation among political parties by looking only at voter demands. Instead, it is the dynamics of party competition that has encouraged parties to adopt an electoral and territorial logic of action. The article shows that the main driver of territorial reform in Belgium has been the continuous relevance of regionalist parties in the Flemish party system, which have compelled mainstream parties to accommodate their demands for territorial autonomy, and, more recently, independence. Regionalist parties have capitalised on a strong sense of Flemish national identity, itself shaped by long-run structural factors. The article also shows that the adoption of an electoral and territorial logic has been strengthened by the split of the Belgian party system and the reinforcement of social cleavages, and, more recently, by the increasing competitiveness of elections and the opening up of party competition at multiple levels.
