Debates on economic disparities have led to the emergence of a new category in historical research during the 1990s: internal peripheries. This category is based on Immanuel Wallerstein’s world system framework on the one hand, and on the studies on regional differentiation from a historical perspective that have taken place since the 1960s on the other. Internal peripheries, Hans-Heinrich Nolte claims, are spaces organized in order to benefit people living elsewhere, i.e. in the core area.
