This paper examines recent debates on the European Union's (EU) constitution and their impact on territorial politics in Spain. Analysis of the preferences and participation of autonomous communities and minority nationalist parties in treaty decision processes and the 2005 Spanish referendum, addresses questions about the mobilization of territorial actors, their ability to influence politics beyond the state, political cleavages on EU issues and the role of European integration in domestic disputes on nationalities questions. I argue that innovations in EU treaty processes provided new access for some Spanish territorial actors, but treaty outcomes reflected their limited impact. Ethno-territorial and ideological cleavages present in domestic politics on territorial matters extended to EU issues with territorial dimensions. Finally, while constitutional treaty debates provided minority nationalist leaders with opportunities to articulate distinctive political profiles both at home and abroad, scope for consensual accommodation of national differences within Spain by way of European integration made little progress.
