The Intelligenzaktion (German pronunciation: [ɪntɛliˈɡɛnt͡s.akˌt͡sjoːn]), or Intelligentsia mass shootings, was a mass murder conducted by Nazi Germany against the Polish intelligentsia (teachers, priests, physicians, and other prominent members of Polish society) early in the Second World War (1939–45). The operations were conducted to realise the Germanization of the western regions of occupied Poland, before territorial annexation to the German Reich.

The mass murder operations of Intelligenzaktion killed 100,000 Polish people; by way of forced disappearance, the Nazis imprisoned and killed selected citizens of Polish society, identified before the war as enemies of the Reich; they were buried in mass graves at remote places. To facilitate the depopulation of Poland, the Nazis terrorised the general populace with the public, summary executions of selected intellectuals and community leaders, before effecting the expulsions of the general population from occupied Poland. The executioners of the Einsatzgruppen death squads and the local Volksdeutscher Selbstschutz, the German-minority militia, pretended that their police-work was meant to eliminate politically dangerous people from Polish society.
The Intelligenzaktion was a major step towards implementing Sonderaktion Tannenberg (Special Operation Tannenberg), the installation of Nazi policemen and functionaries — from the SiPo (composed of the Kripo and Gestapo), and the SD — to manage the occupation and facilitate the realisation of Generalplan Ost, the German colonization of Poland. Among the 100,000 people killed in the Intelligenzaktion operations, approximately 61,000 were of the Polish intelligentsia, whom the Nazis identified as political targets in the Special Prosecution Book-Poland, compiled before the war began in September 1939. The Intelligenzaktion occurred soon after the German invasion of Poland (1 September 1939), and lasted from the autumn of 1939 until the spring of 1940; the mass murder of the Polish intellectuals continued with the operations of the AB-Aktion.
Adolf Hitler ordered the murder of the intelligentsia and the social élites of Poland to prevent them from organising the Poles against their German masters, and thwart the occupation and colonisation of the country; the mass murder was to occur before the annexation of Poland to the Greater Germanic Reich:
Once more, the Führer must point out that the Poles can only have one master, and that is the German; two masters cannot and must not exist side by side; therefore, all representatives of the Polish intelligentsia should be eliminated [umbringen]. This sounds harsh, but such are the laws of life.
Nazi racialism considered the Polish élites as being most likely of German blood, because their style of dynamic leadership contrasted positively against the “Slavonic fatalism” of the Russian people; nonetheless, the extermination of such national leaders was necessary, because their patriotism (moral authority) would prevent the full-scale Germanization of the enslaved populace of Poland.
Moreover, by way of the Rassenpolitisches Amt der NSDAP (Nazi Party Office of Racial Policy), the racially valuable (Aryan-looking) children of the Polish intelligentsia were to be kidnapped to the Reich proper, for Germanization; Nazi ideology claimed that such non-Slavic acculturation would prevent the generational resurgence of the Polish intelligentsia, and thus prevent the resurgence of Polish nationalism in Germanised Poland.
Upon controlling Poland, the German Nazis arrested, imprisoned, and killed approximately 61,000 people as enemies of the German Reich, all of whom were identified as the intelligentsia of each city, town, and village. Each man and woman was biographically listed in the Special Prosecution Book-Poland (Sonderfahndungsbuch Polen), which German citizens of Poland loyal to the Nazi party in the German Reich compiled before the war for the German police and security forces of the SiPo (Security Police) and the SD (Security Service).
The Einsatzgruppen and the Volksdeutscher Selbstschutz, the Ethnic Self-defence militia of the German minority in Poland, were to kill the intelligentsia identified in the Special Prosecution Book–Poland. Aware they would be killing unarmed civilians, the commanders of the paramilitary militias strengthened morale with ideological and racialist instructions to the soldier–policemen, that their political role in the ethnic cleansing of Poland (executions, counterinsurgency, policing) would be more difficult than fighting in battle against soldiers; as noted by Martin Borman, in a meeting (2 October 1940) between Hitler and Hans Frank:
The Führer must emphasize, once again, that for Poles there is only one master, and he is a German; there can be no two masters, beside each other, and there is no consent to such, hence, all representatives of the Polish intelligentsia are to be killed. . . . The General Government is a Polish reservation, a great Polish labour camp.
As part of Generalplan Ost, the political purpose of the Intelligenzaktion was extermination of the élites of Polish society, which the Nazis broadly defined as the Szlachta (Polish nobles), the intelligentsia, teachers, social workers, judges, military veterans, priests and businessmen; any Polish man and woman who had attended secondary school, and so could provide nationalist leadership to resist the Nazi occupation of Poland.
