The Origins of Hitler's Geopolitics

Evidence seems incontrovertible that the concepts and language developed to support the new discipline of geopolitics was understood by Hitler. There was even an indirect link for Hitler to the British geographer, Halford Mckinder, generally regarded as one of the founding fathers of geopolitical thinking. In 1904, Mckinder wrote an essay in The Geographical Journal on the geographical pivot of history. His purpose was to warn the British Empire that technological advances might be tilting world power away from the maritime empires back to the Eurasian heartland.
