Heydrich created the " Zentralstelle IIP Polen " unit of the Gestapo in order to coordinate the ethnic cleansing of Poles in " Operation Tannenberg " and the '' Intelligenzaktion '' , two codenames for the extermination actions directed at the Polish people during the German occupation of Poland . Among the 100,000 people murdered in the '' Intelligenzaktion '' operations in 1939 – 1940 , approximately 61,000 were members of the Polish intelligentsia : scholars , clergy , former officers , and others , whom the Germans identified as political targets in the '' Special Prosecution Book-Poland '' , compiled before the war began in September 1939
