CHAPTER 04

How the Holocaust Happened

What drives ordinary people to become mass killers? Propaganda, conformity, authority, rationalization — and the question of inoculation against genocide.

Part I
Ordinary Men
Police Battalion 101 and the massacre at Józefów
🎯
The Scene at Józefów
Major "Papa" Trapp wept like a child — then ordered 500 ordinary policemen to execute 1800 Jews.

July 1942. Major Wilhelm Trapp — known affectionately as "Papa Trapp" — assembled his men at dawn, pale-faced, voice choking, tears in his eyes. The Jews in a nearby village were to be rounded up. Working-age men to the labour camp. Women, children, the elderly: shot.

Oh, god, why did I have to be given these orders.— Major Trapp, overheard by his men (Browning, Ordinary Men)

Trapp offered an extraordinary thing: any older man who didn't feel up to it could step down. One stepped forward. Then ten or twelve more. They were dismissed. Almost 500 remained.

When he shot, the entire skull exploded… brains and bones flew everywhere.— Testimony of a Battalion 101 policeman (Browning, Ordinary Men)
  • Executions lasted all day. Alcohol was supplied
  • Many were sick; the word "repugnant" was used repeatedly
  • Some hid in the priest's garden. One ran into the woods and vomited
  • Those who refused were called "weaklings" but suffered no consequences
  • That night: no one talked, no one ate. They simply drank
👤
Who Were These Men?
Not fanatics. Not psychopaths. Ordinary working-class Germans, aged 33–48, raised in the Weimar Republic.

The Order Police were too old to be conscripted into the army. Predominantly working-class. Crucially, too old to have only known Nazi propaganda — they were raised in the democratic era of Weimar.

CB
Christopher Browning
Historian. Ordinary Men (1992) — the definitive study of Battalion 101.
  • By end of 1942: at least 6,500 Jews executed, 42,000 deported to gas chambers
  • "Jew hunts" became so frequent the men called them their "daily bread"
  • Only 10–20% of Battalion 101 abstained from killing by war's end
  • Initial killings were distressing — but the distress subsided with each subsequent death
Nothing would be more misguided than to believe that the SS were a horde of sadists.— An Auschwitz inmate (cited in Browning, Ordinary Men)
⚙️
Compartmentalisation & Division of Labour
Making men cogs in the machine diminished individual personal responsibility.

Even Himmler struggled with the sight. His solution: division of labour. Some worked on trains, some were guards, others filled the gas, some did accounts. The shootings were divided too — some rounded up, others stripped prisoners, the actual shooting often done by Eastern Europeans under German command.

Look at the eyes of the men in this Kommando, how deeply shaken they are! These men are finished for the rest of their lives…— An SS officer to Himmler after witnessing executions in Minsk (cited in Browning, Ordinary Men)

Historian Daniel Jonah Goldhagen argued the steps toward genocide were incremental: verbal assault → physical assault → legal measures (Nuremberg Laws) → emigration → ghettoisation → starvation → slave labour → extermination.

  • Gassing was ordered so there'd be less "direct stressful involvement"
  • Incremental escalation reduced the resistance felt at each step
  • Each person could tell themselves they were only a small part
⚡ QUICK CHECK

After decades of research, how many cases were found of Germans punished for refusing to kill Jews?

A Hundreds — refusal meant execution
B Zero — no one was ever punished for refusing
C A handful of high-profile cases
Exactly. This is one of the most disturbing findings: absolutely no cases have been found of anyone being punished for refusing to follow orders to kill Jews. The "just following orders" defence collapses.
Zero. Not a single case. Many were able to avoid killing, as we saw at Józefów. The "just following orders" defence doesn't hold up — the men chose to participate.
Part II
Conformity & Authority
Milgram, groupthink, and the psychology of obedience
🧪
Milgram's Experiment
"The research requires that you continue" — enough to convince 64% to shock someone to the maximum.
SM
Stanley Milgram
Social psychologist. His obedience experiments were directly influenced by the Holocaust.

Participants were ordered to give supposedly painful shocks to actors screaming in the next room. If they hesitated, the phrase "the research requires that you continue" was enough to convince 64% to continue to the highest pain level.

Men are led to kill with little difficulty.— Stanley Milgram, conclusion of his obedience experiments

But there's a problem: Milgram's participants thought they were doing something right — a scientific experiment, a greater good. This isn't the same as murdering children. Yet the pressure to conform in wartime Nazi Germany was arguably far greater than in a laboratory.

👥
Groupthink & In-Group Pressure
You don't want to be the one who objects. In war, the pressure to conform is existential.
Groupthink: a mode of thinking that people engage in when they are deeply involved in a cohesive in-group, when members' strivings for unanimity override their motivation to realistically appraise alternative courses of action.— Irvin Janis, psychologist (1970s)

Gustav Le Bon identified two forces: anonymity (shared responsibility shrinks personal guilt) and mimesis (actions are copied more readily in crowds). George Simmel showed how the desire to stay in an in-group motivates distancing from the out-group.

  • Those who didn't kill were leaving comrades to do the dirty work
  • They risked ostracism, rejection, losing their support network — in a war
  • The Nazis decreed soldiers in the USSR would be automatically absolved of wrongdoing
  • But conformity alone isn't enough — people still need to believe the action is justified
⚖️
Eichmann & the Banality of Evil
Six psychiatrists described him as "normal." He was "simply following the law of his country."
HA
Hannah Arendt
Philosopher. Coined "the banality of evil" while covering Eichmann's trial in Jerusalem.
Most of the killers were not sadists or killers by nature; on the contrary, a systematic effort was made to weed out those who derived physical pleasure from what they did.— Hannah Arendt, Eichmann in Jerusalem

Six psychiatrists at the trial all described Eichmann as "normal" — "a man with very positive ideas, who personally had nothing against the Jews." The defence argued he was simply following the law.

  • Milgram's key insight: hierarchy leads people to adopt their superiors' "definition of the situation"
  • Moral responsibility is passed upward — like personal responsibility is diminished in a crowd
  • But this still requires a rationalisation — a belief the authority is legitimate
⚡ QUICK CHECK

Why does the author argue that conformity and authority alone can't explain genocide?

A Because most people refused to participate
B Because there was no real authority structure
C Because every action still requires a rationalisation — a belief that the action or the authority is legitimate
Right. Conformity and authority provide part of the answer — but there is always a context, always a rationalisation. The killers had to accept some version of the Nazi "definition of the situation."
Most people didn't refuse, and there was a clear authority structure. The point is that conformity and authority are necessary but not sufficient — people still need a rationalisation, a belief framework, to justify pulling the trigger.
Part III
Rationalisation
"It is always a simple matter to drag people along" — how murder is justified
🧠
How Murder Is Justified
"Us or them." "They're bombing your wives." "Nothing could be done with such people." "The humane thing to do."
It is always a simple matter to drag people along whether it is a democracy, or a fascist dictatorship. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism. It works the same in every country.— Hermann Göring, at Nuremberg
  • "We are at war" — "they're bombing your wives and children back home"
  • Killing prisoners was "humane" — food was short, they wouldn't survive the winter
  • "Nothing could be done with such people" — "the Jews were not going to escape their fate anyway"
  • One man justified killing a child because they wouldn't survive without their mother
  • The T4 programme called the murder of disabled people "mercy killings"
It was indeed a medical matter, since it was prepared by physicians; it was a matter of killing, and killing, too, is a medical matter.— Eichmann's lawyer, at trial
🔄
Victims Who See Themselves as Victims
The perpetrators of genocide often see themselves as the victims. Germany as the besieged hero.

Anti-Jewish policies were portrayed as responses to Jewish aggression. Germany was the victim; the Nazis were heroes defending against Judeo-Bolshevik world domination.

  • 1933: Jewish boycott of Nazi Germany → Hitler retaliates with boycott of Jewish shops
  • 1937: A diplomat murdered by a Jewish refugee → Kristallnacht, 100 killed, 3000 sent to camps
  • Anti-Semitic actions were always presented as defensive
  • Treaty of Versailles: "harsh, unfair, punishing" — genuine grievance weaponised
The historical guilt of world Jewry for the outbreak and expansion of this war has been so extensively demonstrated that there is no need to waste any more words on it. The Jews wanted their war, and now they have it.— Joseph Goebbels, radio broadcast, 1941
Part IV
The Propaganda Machine
Seven years of ubiquitous ideology before the first shot was fired
📢
Total Media Control
By 1939 the Nazis controlled 82% of newspapers. Press directives issued daily at noon. No free press survived.
Propaganda uses the language of virtuous ideals to unite people behind otherwise objectionable ends.— Jason Stanley, philosopher
  • Ministry for Public Enlightenment and Propaganda (RMVP) controlled all culture
  • 200 social democratic and 25 communist newspapers closed immediately
  • Daily press directives dictated stories, language, and presentation
  • "Word of the week" posters: "must not be absent anywhere… must penetrate every last community"
  • The Franz Eher publishing house became the largest publisher in the world
All effective propaganda must be confined to very few points which must be brought out in the form of slogans.— Adolf Hitler, Mein Kampf
🕸️
The Conspiracy Theory
Jews controlled Wall Street, Hollywood, the USSR, Britain. Once a global conspiracy is defined, evidence always fits.

The Nazis were motivated by a conspiracy theory that Jews were plotting world domination. Every event was twisted to fit. An unknown author's book was presented as official US policy. Churchill hiring a leftist minister proved "the Jewification of the British government."

Roosevelt Main Tool of Jewish Freemasonry; Sensational Document Reveals Connections of the Warmonger with the International Clique.Der Völkische Beobachter headline, 1941
The Jews are a parasitic race that feeds like a foul fungus on the cultures of healthy but ignorant peoples. There is only one effective measure: cut them out.— Joseph Goebbels, "The Jews Are Guilty!" (1941)
  • Once a global conspiracy is defined, evidence can always be found to justify it
  • Jews depicted as "masters of mimicry" — hiding in plain sight
  • One study: Germans who lived through the Nazi era had 2–3x more anti-Semitic views than those who didn't
📜
2000 Years of Antisemitism
From "Christ-killers" to Social Darwinism — the oldest prejudice weaponised by modern pseudoscience.
Where Christ-killers gather, the cross is ridiculed, God blasphemed, the father unacknowledged, the son insulted, the grace of the spirit rejected.— John Chrysostom, 5th century

Jewish people were stateless, had no allegiance to the nation or Church, lived in a culturally different way. Over centuries they became the easiest lightning rod, the eternal scapegoat. But it took Social Darwinism, eugenics, and racial ideology in the 19th century for antisemitism to develop into its modern genocidal form.

  • Pogroms in Russia motivated by conspiracy theories that Jews murdered Christian children
  • The Nazis added biological pseudoscience to millennia of religious prejudice
  • Goebbels: "The Jew is the enemy and destroyer of blood-based unity"
⚡ QUICK CHECK

What is the key mechanism by which conspiracy theories sustain themselves?

A Once a global conspiracy is defined, evidence can always be found to confirm it
B They rely on a single charismatic leader to repeat them
C They only work in totalitarian states with no free press
Right. This is the self-reinforcing logic of conspiracy: once the framework is established, every event — no matter how unrelated — can be twisted to fit. An unknown author becomes "proof" of state policy. A political appointment becomes "Jewification."
While leaders and media control matter, the key mechanism is self-reinforcing logic: once a conspiracy framework is defined, every event can be twisted to confirm it. That's what makes conspiracy theories so persistent — even without a single leader.
Part V
Inoculation
The warning signs, the models, and the moral vaccine
🧅
The Layers of the Onion
Trigger → order → conformity → authority → ideology → crisis → frustration of basic needs. The core is the seed.

Working backwards from a murder by peeling layers: the trigger happened in a context of orders, authority, conformity, and rationalisation. But those weren't enough — deeper motivators had already been planted.

ES
Ervin Staub
Psychologist. His model of genocide identifies three initial stages leading to mass violence.

Staub's three stages: (1) Frustration of basic needs. (2) An out-group is identified as the cause. (3) The in-group is motivated by a utopian vision that excludes that group.

🔑
Kelman's Three Requirements
Authorization, routinization, dehumanization — when standard moral principles cease to apply.
HK
Herbert Kelman
Social psychologist. His framework identifies three processes that enable genocide.
Through processes of authorization, the situation becomes so defined that standard moral principles do not apply. Through routinization the action becomes so organized that there is no opportunity for raising moral questions. Through dehumanization, the actor's attitudes become so structured that it is neither necessary nor possible to view the relationship in moral terms.— Herbert Kelman
  • Authorization: the individual is absolved of personal moral choice
  • Routinization: no space to raise moral questions — it's just procedure
  • Dehumanization: the target is no longer seen as human — "virus," "fungus," "parasite"
🚨
The Warning Signs
Economic crisis + pronounced social divisions + in-group victimhood + conspiracy theory = maximum danger.
  • Warning 1: Economic difficulty — "the frustration of basic needs" (Staub)
  • Warning 2: Multiple groups with different statuses in a single environment, especially with cultural/religious differences
  • Warning 3: The in-group feels both powerful AND victimised simultaneously
  • Warning 4: Conspiracy theories directed at an out-group take hold
  • Warning 5: Ideological visions that exclude groups — labelling them with dehumanising euphemisms like "virus"

The genocide early warning project currently considers at least 30 countries to be at high risk.

"It Couldn't Happen Here"
"The year was 1937. For the average Jew, this seemed enough. He didn't realize we were all waiting for the end."
A concentration camp, for those on the outside, was a kind of labor camp. There were whispered rumors of people being beaten, even killed. But there was no comprehension of the tragic reality. We were still able to leave the country; we could still live in our homes; we could still worship in our temples; we were in a Ghetto, but the majority of our people were still alive. For the average Jew, this seemed enough. He didn't realize that we were all waiting for the end. The year was 1937.— Ilse Stanley, memoirs

It is always thought that warning signs would come well in advance. That there would be plenty of time. That it couldn't happen here.

💉
The Moral Vaccine
"Cruelty has a human heart." Evil is learned. Which means we all have a responsibility to inoculate.
Just as there is evil in the heart of every man, there is evil at the heart of even the most "civilised" human society.— Mark Bowden

What we've seen is not a philosophy of evil — a biblical tale of angels and devils — but a theory of the incremental development of evil. Evil is moulded and twisted into shape gradually. No person wakes up one day with hate in their heart — it has to be learned.

  • Inoculation means shining a light on these factors when they occur
  • It means education, media responsibility, press standards
  • An ethical baseline with emphasis on fundamental equality between all people
  • "Cruelty has a human heart" — William Blake
  • We all have a responsibility to inoculate ourselves and our cultures from what always lurks within
⚡ FINAL CHECK

What does the author mean by a "theory of the incremental development of evil"?

A That evil people are born, not made
B That evil is moulded gradually through small steps — no one wakes up with hate; it has to be learned
C That genocide only happens through top-down orders from leaders
Exactly. This is the core thesis: evil is not biblical, not black and white. It develops incrementally — through minor changes, small rationalisations, gradual escalation. Which means it can be identified and stopped early, if we know what to look for.
The key point is that evil develops gradually through small steps, rationalisations, and escalation. No one is born a mass killer — it is learned. And because it is learned, it can be recognised, interrupted, and prevented.
