The aim of this tentative article is to bring some further empirical evidence in order to validate Stein Rokkan's "Conceptual Map of Europe". Therefore a set of variables are suggested: territorial-cultural (monocephalic unitarism with two possible ways the hegemonie and the authoritarian and polycephalic) and territorial-economic (metropolitan, triangles and conurbations, and polycephalism). Some indicators are proposed to provide some measurement of the variables, such as Beaufays Federalism scale or a new Mediatie centralization scale.
