Answer
Rudolf Hess, a prominent figure in the Nazi Party, was a student of the German geopolitician Karl Haushofer. Haushofer's theories on geopolitics, which emphasized the importance of geography in shaping political and military strategy, greatly influenced Hess and his worldview. Hess applied these ideas to the Nazi Party's expansionist ambitions, particularly in the context of the "Lebensraum" concept, which sought to acquire territory for German settlement.
