European cities are on the rise, and are taking advantage of the opportunities of the European integration and globalization processes. But they also face economic changes, social inequalities, poverty and a new set of constraints. Taking examples through the European Union, European Citiesexplores the impact of the transformation of the nation states on cities and the change of local societies and local governments. It argues that new modes of urban governance are emerging, and that cities are becoming collective actors within European governance. European Cities shows why and how the bulk of European cities still appear to be original forms of compromise, aggregation, representation of diverse interests, and culture. Different modes of governance are gradually being structured in most middle size European cities despite processes of socialexclusion segregation accompanied by the increased mobility of some citizens. Are Europeans going to invent a new form of institutionalized and territorialized capitalism, of which medium-sized European cities will be one of the pillars and one of the actors ? Failing that, the effects of changingscales could be expressed as profound transformations of the European urban model.
