Scholars of different schools have extensively analyzed world systems as networks of communication under the fashionable heading 'globalization.' Our collected new research pushes the argument one step further. Globalization is not a homogenization of all social life on earth. It is a heterogeneous process that connects the global and the local on different levels. To understand these contemporary developments this book employs innovative concepts, strategies of research, and explanations. Globalization is a metaphor for different borderstructures, new borderlines, and conditions of membership, which emerge in a global world-system. As a world-system expands it incorporates new territories and new peoples. The process of incorporation creates frontiers or boundaries of the world-system. These frontiers or boundary zones are the locus of resistance to incorporation, ethnogenesis, ethnic transformation, and ethnocide.
