カール・ハウスホーファー
Hitler’s ideas about eastward expansion that he promulgated in "Mein Kampf" were greatly influenced during his 1924 imprisonment by his contact with his geopolitical mentor Karl Haushofer. One of Haushofer’s primary geopolitical concepts was the necessity for Germany to get control of the Eurasian Heartland in order for it to attain eventual world domination.
