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.
