Why does the European Union get that low acceptance by ist citizens? We assume an existing relationship between low acceptance of EU-decisions on one side and high national and regional attachments on the other. Citizens apparently see their traditional (national, regional) identities threatened by integrating activities and therefore react by favoring their respective ingroups. We expect the specific interplay of these identities to be a clue condition in the development of a european identity and will empirically look for that in comparable studies with groups, nations and regions.
