In the late 1960s, however, the so-called 'ethnic revival' in the West indicated that the form of identity had not lost its mobilization potential. The worst manifestations of intra-state ethnonational conflicts in Western Europe have been terrorist campaigns. Territoriality, attachment to a given geographical area, is recognized as a central factor in human activity and human relations, since territories, for groups as well as individuals, are a resource to secure basic needs as survival and reproduction and constitute an important power base. One of the important factors in the context is the connection between territoriality and ethnicity. Ethnic groups need not have any territorial attribution. Like all collective identities, however, ethnic and territorial identities have to be communicated, which is done in a specific but at the same time changing societal environment. The advantage of the all-party strategy is that different social strata have the opportunity to act on the basis of their own social values. © Håkan Wiberg and Christian P. Scherrer 1999.
