The attention of contemporary political science on ethnoterritorial conflicts seems to be limited to the analysis of the most conflictual cases. However, several current centre-periphery conflicts are lacking of a clear political expression. The aim of this paper is to help explaining what happens when does not appear a persistent politization of ethnoregional conflicts, using Sardinia and Brittany as case studies. In these regions ethnoregionalist mobilizations are stronger in the cultual and socio-economic realms, but still weak in the political one. The paper main hipoteses is that the main cause of this weak politization and of the delay in the selfgovernment claims is to be found in the lack of strategic coordination, a "disjointed connection", among the various ethnoregionalist actors engaged in four specific dimensions of the mobilization (historical, cultural, socio-economic and political).
