ABSTRACT
The negative results of the Irish referendum on the Lisbon Treaty have caused a deep crisis as regards European identity in a time when the current eastwards enlargement may dilute the birth of a genuine meaning of citizenship status at EU level. This chapter focuses on what are the most significant impacts of the enlargement processes over the processes of nation-building and the nationality laws of the last acceding EU member states. The process of nation-building is based on two 'core national doctrines' the cultural and the democratic/constitutional doctrine, the combination of which aim at establishing an operative mixture of liberal and national values. Nationalist politics of these newly independent states has also deeply influenced kin-minority relations as well as the social inclusion/exclusion of national, ethnic minorities and the integration of migrants. The issue of nationality law strongly relates to the effects of international migratory movements.
