Karl Ernst Haushofer was a German general, professor, geographer, and politician. Through his student Rudolf Hess, Haushofer's conception of Geopolitik influenced the development of Adolf Hitler's expansionist strategies. He coined the political use of the term Lebensraum, which Hitler adopted in Mein Kampf and used to motivate global Nazi expansionism and genocide. Under the Nuremberg Laws, Haushofer's wife and children were categorized as Mischlinge. His son, Albrecht, was issued a German Blood Certificate through the help of Hess.
