The process of European integration, the complexity of the problems involved and even the resistance it raises, astonishes observers in other parts of the world, especially in large states that have a long history of centralized government behind them. Is there really so little unity in Europe? If so, how can this be explained? Has European diversity generated only problems or has it, in fact, created new and unique opportunities? Is there a chance that growing concerns at EU-level about the cultural dimensions of European citizenship could, in fact, consolidate a sense of community? And, finally, how can historians contribute to the creation of a common European identity, if this is so weakly developed?
