, where they often died. Memorials to the victims of AB have been erected in many of the places, usually in remote forests, where they were taken to be shot.
While AB was at first a major setback to the resistance, it soon recovered. By late 1941 the German authorities decided to instead use tactics that more specifically targeted known or suspected underground groups, as Poles from all walks of life began to take action against the occupiers, contrary to German expectations. Mass executions did continue as a method of state terror and, later, the extermination of Jews, Roma and others the Nazis considered racially undesirable. After the war, some of those responsible, such as Frank, were executed for war crimes, while others involved at lower levels either died before they could be tried on the charges they faced, or evaded prosecution by living under assumed names.
History
The Nazis considered the
Polish intelligentsia to include not just the country's academics and artists, but its politicians, artists, aristocrats, professionals, clergy, present and former military officers, and generally everyone sufficiently educated or wealthy to have a position of authority, even informally, in Polish society. Their ideology held that only these people had a true
national consciousness; the rest of the population was indifferent to the fate of the state and cared more about their daily lives. Once the intelligentsia had been eliminated, the Nazis believed the remaining Poles would be useful to them as unskilled labour.
''Intelligenzaktion''
The first mass murder of the intelligentsia, and any other people suspected of potential anti-Nazi activity, began in September 1939 as German troops began
invading Poland and continued until the next spring.
This was seen by Nazi Germany as a pre-emptive measure to keep the
Polish resistance scattered and to prevent the Poles from revolting during the planned German
invasion of France.
The first killings of Polish intelligentsia took place soon after the invasion. It was called the ''

By May 1940, Polish society had begun to recover from the previous year's military defeat, leading to an increase in
resistance activity. With international attention diverted from Poland by the German invasion of France, Nazi German authorities thus decided the time was ideal for another anti-intellectual purge, this time to focus on the areas within the General Government.
''AB-Aktion''
The ''Intelligenzaktion'' was continued by the German ''AB-Aktion'' Operation in occupied territories of central Poland. Both murder operations were conducted in part according to an "enemies of the Reich list" prepared before the war by members of the

German preparations and planning
The later anti-Polish ''AB-Aktion'' had its roots in discussions with Soviet officials during a series of secretive
Gestapo–NKVD conferences that began at the end of September 1939 after the two nations had defeated and divided Poland.
A secret protocol in the
German–Soviet Boundary and Friendship Treaty
The German–Soviet Boundary and Friendship Treaty was a second supplementary protocol of the Molotov–Ribbentrop Pact of 23 August 1939. It was a secret clause as amended on 28 September 1939 by Nazi Germany and the Soviet Union after thei ...
signed at that time bound both parties to "tolerate in their territories no Polish agitation which affects the territories of the other party
ndsuppress in their territories all beginnings of such agitation." By the end of the talks in March 1940 the two secret police agencies had begun primarily discussing how to suppress the resistance.
By that time Hitler had also personally charged GG governor-general
Hans Frank with keeping Poland under control to avoid any distractions during the upcoming actions on the Western Front. Accordingly, on March 2, 1940, Frank convened a meeting with the military and security leadership and all four leaders of the GG's districts, to announce Aktion AB, its name from the words for "extraordinary pacification" in German. Noting that resistance organisations had already arisen, he warned that "we may wake up one morning and find ourselves overwhelmed by them if we do not soon launch a large-scale attack against at least their leaders." At a meeting six days later he revealed that this initiative came on Hitler's personal orders. "The slightest attempt by the Poles to take action will result in a massive liquidation action against them", he warned. "I would not hesitate to use any method of terror and I would not shrink from any consequences."

At a 16 May Kraków meeting with Streckenbach and GG administrative officials, Frank reiterated the danger posed from within. Citing the ongoing
partisan actions of the
Detached Unit of the Polish Army and other recent incidents of attacks and sabotage against Germans and the occupying military, the attendees agreed to initiate a plan to ensure that "the Polish resistance movement will be deprived of its leaders, the authority of the Führer and the Reich in the General Government will increase enormously, and peace in the country will be unconditionally maintained." All actions towards this end were to be centrally coordinated and authorised in order to emphasize German authority over the GG. Frank ordered Streckenbach to begin Aktion AB immediately and granted him special legal authority to take those steps. It was expected that operations would conclude a month later, with the cases to be heard in ''Standgerichten'', special temporary police courts, afterwards.
Two weeks later, after the operation had started, another meeting was held to discuss the progress and further elucidate its goals and methods. Frank made it clear to all concerned that Aktion AB was specifically aimed at preventing the Poles from taking advantage of the invasion of France and the Low Countries to mount an uprising, which he described as a duty participants owed to the Reich. For the first time he used the word "liquidation" to describe the goal of the operation, estimating that it would cost the lives of at least several thousand Poles. Streckenbach reported that half of "the flower of Polish intelligentsia and resistance" had been arrested; he estimated that 75% of the total would be in German hands by the conclusion of Aktion AB. Most of the arrested would simply be shot shortly afterwards rather than sent to camps, it was decided. This, for Frank, was a lesson learned from the arrests of the Jagiellonian professors, which led to unnecessary "hassle" and would have turned out differently had the Germans just killed them. He also ordered any Polish prisoners still held in camps in the Reich to be returned to the GG to avoid overburdening those camps.
Aktion AB was envisioned not as the final action necessary to suppress the resistance but as merely the second of what were likely to be several. Through AB the Germans sought particularly to intimidate the whole population as they further eliminated those they believed could lead the resistance To that end, they arrested 3,000 known criminals in order to discredit the intellectuals they were murdered alongside.
Ernst Zörner, governor of the
Lublin District, requested that workers and peasants be dropped from the lists for economic reasons, suggesting that originally the scope of Aktion AB had been broader.
Operation

A catalyst for the liquidation of most prisoners was Frank's desire to avoid sending GG arrestees to camps in the Reich. But on a visit to Warsaw at the end of April, as planning for Aktion AB was getting underway, Reichsführer

. For many, the camps were a place to be held until a sufficient number had arrived to be shot, as happened to many prisoners from Warsaw at
Mauthausen in the autumn of 1940.
Stanisław Grzesiuk reports that Gestapo officers from that city were believed to be on hand to personally choose those to be shot.
The majority of those arrested were, however, not transported to camps but shot
en masse at selected sites in remote forests within the GG after being questioned about any involvement in or awareness of resistance activity. The ''Standgerichten'' were used to provide a veneer of due process to the executions in some cases, but usually condemned the accused on thin grounds. On the orders of
Friedrich-Wilhelm Krüger, the GG's SS commander, units carrying out the executions were provided with "spiritually valuable" entertainment after completing their duties.
Warsaw District
Many of those taken by Aktion AB came from Warsaw, not only Poland's capital but its social and cultural centre. The arrests began at the end of March, targeting politicians, activists, teachers and professionals, all categories that in the opinion of the city's SS commander,
Josef Albert Meisinger, could play a significant role in inciting and leading resistance to German rule. Among them were
Maciej Rataj
Maciej Rataj (19 February 1884 – 21 June 1940) was a Polish politician, speaker of the Polish Parliament and deputy President of the Republic of Poland, and writer.

Conclusion
Several dates are given for the end of Aktion AB. The original plans called for all operations to be over by 15 June, and this date is sometimes considered to be the end. But Streckenbach did not report that AB was over for almost another month, and Frank announced at a 23 July conference that it was finished. Transports to the camps and executions continued past that date, into the later months of 1940. From August to February, about 4,770 people were sent to camps from Warsaw area prisons. Historian
Krzysztof Dunin-Wąsowicz thus considers Aktion AB to have symbholically ended on 17 January 1941, the day Streckenbach was dismissed from the GG.
The active persecution of Polish intellectuals continued until the end of the war. The direct continuation of the AB Aktion was a German campaign in the east started after the
German invasion of the USSR. Among the most notable mass executions of Polish professors was the
massacre of Lwów professors, in which approximately 45 professors of the university in

Victims

Aktion AB was one of Nazi Germany's deadliest acts of state terror in occupied Poland. While officially it was explained as a necessary response to the growth of the Polish resistance, its real purpose was to eliminate as many people as possible from the country's actual or potential leadership, and thus diminish Polish national identity. It also directly continued what had been started with the ''

There is no single comprehensive history of Aktion AB, and historians have not yet been able offer a full accounting of it. Most significant among the unknown facts is the exact count of victims.

,
Czesław Madajczyk and other Polish scholars have generally accepted Streckenbach's figure of 6,500—approximately 3,500 intelligentsia killed, along with 3,000 criminals. However, his accounting has never been verified, so that number is not considered authoritative. Records pertaining to the execution of the criminals are particularly fragmented and incomplete; it cannot be determined from them how many of those 3,000 actually were criminals. The deportation of many of those spared execution to concentration camps that few survived further complicates reaching an accurate count of the victims.
Effect on resistance

At first, as the Nazis had hoped, the rapid killing of so many members of the Polish athletic, cultural, economic, political and social elite had a damaging effect on the resistance, as many of its leaders and members were among those executed or deported. The Gestapo was able to augment Aktion AB with several raids on small units of the
Union of Armed Struggle (ZWZ), leaving what resistance organizations remained, already demoralized by the
fall of France that June, chaotic and scattered. In November ZWZ general
Stefan Rowecki wrote to the

in addition to eliminating several connections over the Slovak border, forcing the ZWZ to take even greater precautions.
In the longer term, however, Aktion AB had no effect on the growth of the resistance. Despite the setbacks he admitted, Growecki's reports to London also document continued activity. The ZWZ's calls to Poles to remain calm and focused blunted German hopes of intimidating society. "Despite irreparable severe losses to Polish society, it stands taller", Growecki wrote in a January 1941 report. "More and more people are convinced that the losses to terror are war losses in the fight for survival and victory. Despite the terror, people continue to conceive plans for civil war and sabotage."
The German occupying authorities, too, came to doubt the long-term efficacy of Aktion AB. Officers in the security services believed that such ''ad hoc'' actions yielded minimal results that, ultimately, did not impede the growth of the resistance. Streckenbach conceded at a GG meeting a year after the operation that the belief that resistance came exclusively from those who had been officers, officials, activists or highly educated had been "mistaken and very dangerous". While that did account for a core group of the resistance leadership, he conceded, it had been largely "peasants and workers" carrying out its actions. As a result the GG decided, after concluding Aktion AB, to forsake similar mass actions, at least for a while, and concentrate instead on targeting specific Polish resistance cells.
Fate of perpetrators

Exactly how many people, and who, among the German occupying authorities were responsible for Aktion AB has never been conclusively established. Frank, as governor-general, bears most of the responsibility along with Krüger and Streckenbach, the senior SS officials in the GG. The four district governors—
Ludwig Fischer (Warsaw),
Otto Wächter (Kraków),
Ernst Zörner (Lublin) and
Karl Lasch (Frank's brother-in-law) (Radom)—also were intimately involved in planning the operation, along with the district SS and police commanders like

and
Fritz Katzmann. Those plans were then implemented by the SD and SP in the districts, led by Meisinger and
Ludwig Hahn, among others. Many lower-level members of those organizations also took part; those who sat on the ''Standgerichten'' bear special responsibility since they handed down formal death sentences when those were desired.
A few of the perpetrators were tried for crimes against humanity, including Aktion AB, after the war. Frank and his deputy,
Arthur Seyss-Inquart, were convicted at

and hanged. Fischer, Meisinger and
Josef Bühler, State Secretary of the GG, were tried in Poland under the
Moscow Declarations as that was where they had committed their crimes. They were convicted by the
Supreme National Tribunal (NTN) and hanged as well.

when he was arrested in 1960. Two attempts to bring him to trial failed due to insufficient evidence to support the charges; in 1972 he was finally tried, but convicted only on charges related to the execution of Polish political prisoners at Pawiak in 1944 and sentenced to eight years. In 1975 he was convicted of other charges relating to the deportation of Warsaw Jews to

Before the war was over, Lasch faced German criminal charges. In August 1941 he was appointed governor of the newly created
District of Galicia, an area attached to the GG that had been part of the

before the war. A pawn in a power struggle between Frank and Himmler, he was relieved of that position and jailed in Kraków at the beginning of 1942 on embezzlement charges. Before Lasch was tried, he was shot at the prison in Wrocław at Himmler's order; whether by his own hand or a firing squad remains unclear, as does the exact date.
Some other perpetrators of AB, like many other prominent Nazis,
took their own lives as the war ended. Krüger, having survived a 1943 assassination attempt in Kraków, went on to command Waffen-SS units in Yugoslavia, Finland and finally Austria, where he killed himself in May 1945 as Germany surrendered. Globočnik, too, was in Austria at that time. Captured by British troops along with other wanted Nazis, he took a cyanide capsule and died before he could be questioned. Liphardt, too, took his own life in a

declared legally dead as of 21 December 1945 was granted.
A few avoided trial entirely. Streckenbach, after declining a senior SS post in Austria in 1943, served in the Waffen-SS at his request until being taken prisoner by the Red Army, along with other survivors of

Alleged coordination with Soviets

of Polish army officers it had taken prisoner when
invading the country from the east as Germany had from the west the preceding September. This has led to speculation that the two powers coordinated their targeting of Polish leadership classes and that the Germans were aware that the Soviets had perpetrated Katyn, which German officers were tried for after the war, responsibility which the Soviets insisted on for decades until admitting their own culpability around the time the USSR collapsed.
The March 1940 GG meeting at which AB was authorised preceded by three days a meeting of the
Soviet Politburo that similarly resulted in the decision to murder the captive Poles. At one of a series of
Gestapo-NKVD conferences, held near

Zakopane (Gorals#Language, Podhale Goral: ''Zokopane'') is a town in the south of Poland, in the southern part of the Podhale region at the foot of the Tatra Mountains. From 1975 to 1998, it was part of Nowy Sącz Voivodeship; since 1999, it has ...
, it has been argued that the plans for both AB and Katyn were shared and agreed by both sides.
Allegations of coordination are disputed by other historians. None of the documentary evidence from the Zakopane meeting, or any other Gestapo-NKVD conference, records any suggestion the two sides informed each other of their plans to murder many members of Poland's elite.
Extant Soviet records also suggest that such cooperation was improbable. It has thus been reasonably assumed that the Germans were unaware of the Katyn massacres until they unearthed the bodies after taking the area in 1943 and convened the
Katyn Commission.
