Book excerpt: The political structure of Europe has changed and continues to do so. The changing allegiances of the popluations of Europe pose problems and challenges for social psychological theory. Changing European Identities explores these issues using social identity theory and alternative models such as alienation theory and representational identity theory. It provides a highly topical and relevant context for exploring the validity and limits of current theories. Providing a valuable new perspective on people's reactions to change in Europe, it will be useful for advanced scholars in psychology and other social and political sciences.
