The fundamental aim of this work consists in pointing out the nationalitarian term such as effective and scientific in order to observe and explain the appearance of territorial regeneration and linguistico-cultural recovery plans. The latter assert themselves in formerly identified towns and communities which, in more recent times of history, had disappeared on behalf of the plan the Modern State created on the Nation. In different parts of the world, in an era where planetarization of the system is clearly predominant, the collective action forms, based on the ethnic group and the nation, have been relaunched trying to attribute a stable and recognized basis to the identity of individuals and groups, in a context that has lost its traditional borders. What does the fact that the same kind of nationalitarian movements occurred as much within consolidated democracies as in authoritarian systems mean? Which are the laws that follow those processes? How is it possible that an historical social framework which was belittled to collective memory, works again with a promising plan? What are the conditions that cause in fact the structuring of nationalitarian movements? How is the nationalitarian categorization and identification made? What part does the symbolic and representational production play in the identity recovery? In what conditions do minority movements manage to be triumphant? What is the role of values in collective decision-makings?
