Bringing together a range of specialists in their respective fields, the book provides a combination of original research with fundamental questions about why states stay together, and above all why sometimes they fall apart. When and under what conditions is the separation of one part of a state from another justified? Written in an accessible and informed manner, the authors seek to answer this question on the basis of ten case studies and a general review of the literature and theories of the question.

This book examines the fortunes of social democracy since 1989 in the former GDR, Poland, Hungary, the Czech Republic and Slovakia, setting the analysis in a broader European framework, and relating the current problems of social democracy in western Europe to developments in the east of the continent.
