The idea of Mitteleuropa began to gain momentum in the German geopolitical science of the beginning of the twentieth century. German geopolitics, which became famous through the works of Karl Haushofer, had set out a geographical and political notion of Mitteleuropa that supported a political project based on German expansion. As such, Mitteleuropa developed as both a political and scientific concept, a project and a `reality'. With an analysis of the core elements defining the term Mitteleuropa one can begin to (...) appreciate the characteristics that differentiate it from other geographical concepts, as well as the features which some conservative authors have promoted following the geopolitical scientists. As a `geopolitical idea', Mitteleuropa can be shown to designate a way of understanding politics, nature and culture, or more specifically, their relationship. (shrink)
