Long-Term Ideology Made Genocide Thinkable Long Before the War Began
Note
This article addresses the following inquiry question: How did long-term antisemitic ideology, from medieval religious prejudice to Nazi racial theory, help create the conditions for the persecution and mass murder of marginalised groups in Nazi-occupied Europe?
Religious and Medieval Antisemitism
Centuries of religious persecution. For over a millennium, Christian Europe framed Jews as Christ-killers, blasphemers, and alien intruders. Medieval persecution included forced conversions, expulsions (England 1290, France 1394, Spain 1492), pogroms, and confinement in ghettos, with the blood libel accusation (that Jews murdered Christian children for ritual purposes) periodically provoking massacres.
A reservoir of prejudice. These traditions persisted in folk culture and religious teaching into the 20th century, giving Nazi propaganda an existing base of hostility to build on rather than having to invent antisemitism from nothing.
The shift to racial antisemitism. Religious antisemitism targeted Jews as a religion and offered conversion as an escape route. The 19th century added a more dangerous dimension: racial antisemitism, which presented Jews as a biological threat that could not be dissolved by baptism or assimilation.
Why this mattered. Once antisemitism was redefined as hereditary rather than religious, no change of belief could remove a Jewish person from the category of "threat" , a precondition for genocide rather than ordinary discrimination.
Nazi Racial Ideology
Hitler's ideological synthesis. In Mein Kampf (1925-26), Hitler combined existing antisemitic traditions with Social Darwinist thought, Germanic nationalism, and anti-Marxist politics. He presented history as a racial struggle in which the superior Aryan race had to defeat the parasitic Jewish race, which he held responsible for Marxism, capitalism, and Germany's defeat in the First World War.
An active enemy, not just an inferior race. Jews were not presented merely as biologically inferior in this ideology , they were framed as an active force of destruction working against Aryan civilisation, which made their removal seem not just permissible but necessary.
From ideology to policy. This worldview shaped Nazi policy from 1933. The Nuremberg Laws (1935) stripped German Jews of citizenship and banned marriage and sexual relations between Jews and "Aryans."
A bureaucratic precedent for killing. The T4 programme (1939-41) killed approximately 200,000 disabled Germans through "euthanasia," establishing the organisational and psychological precedents for mass murder on racial grounds. The Nuremberg Laws defined who was Jewish. T4 demonstrated that racial killing was organisationally possible.

What precedent did the T4 programme (1939-41), which killed approximately 200,000 disabled Germans, establish for the later Holocaust?
Markscheme
The T4 'euthanasia' programme killed about 200,000 disabled Germans between 1939 and 1941, establishing the organisational and psychological precedents that made mass murder on racial grounds seem administratively possible; the Nuremberg Laws, by contrast, had already defined who was legally Jewish.

Case study
Mein Kampf and Its Significance
Hitler wrote Mein Kampf in prison after the failed Beer Hall Putsch of 1923. Published in two volumes (1925 and 1926), it combined autobiography with ideological statement.
The book set out his racial antisemitism, his theory of Aryan racial superiority, his vision of Lebensraum (living space) in the east, and his belief that Jews were behind both Marxism and international capitalism.
It sold 5.2 million copies in Germany by 1939. After the Nuremberg Laws were passed, it was given to every newly married couple by the state. Its programme was not hidden.
The Road to Genocide: Escalating Persecution, 1933-1941
Legal exclusion and economic pressure, 1933-1938. Nazi persecution escalated in stages. From 1933 to 1938 it focused on legal exclusion and economic pressure: the April 1933 boycott of Jewish businesses, the Nuremberg Laws (1935), and the forced "Aryanisation" of Jewish-owned businesses.
Kristallnacht: from law to violence, November 1938. Kristallnacht (the "Night of Broken Glass") marked a shift to open physical violence: 267 synagogues were burned, 7,500 businesses smashed, and 30,000 Jews arrested and sent to concentration camps.
War brings ghettoisation, 1939-1941. The invasion of Poland in September 1939 brought three million Polish Jews under German control. Ghettos were established in Polish cities from 1939-40, concentrating Jewish populations under German administration with restricted food, no right of movement, and disease deliberately propagated through overcrowding.
The Warsaw Ghetto. Established in October 1940, it confined 400,000 people in an area of 3.3 square kilometres , conditions engineered to produce starvation and disease.
Historiography
Lucy Dawidowicz (intentionalist): argued that Hitler planned the mass murder of the Jews from the 1920s onward, with Mein Kampf itself functioning as an early blueprint for later genocide.
Hans Mommsen (functionalist/structuralist): argued the genocide emerged from the cumulative radicalism of competing Nazi agencies seeking to please Hitler, rather than from a single pre-existing plan.
Christopher Browning and Ian Kershaw (synthesis): propose that Hitler held a fixed long-term goal of eliminating the Jews from German life, but that the specific decision to pursue industrial genocide was made in response to wartime circumstances, particularly the 1941 invasion of the USSR.
Judgement: Long-term ideology explains the direction and moral permission behind persecution , who was targeted and why it seemed justified , but it does not by itself explain the precise timing and mechanics of the shift to industrialised mass murder, which depended on the military and political factors covered elsewhere in this section.
Key Idea
Nazi ideology drew on a real, respected scientific movement, not just fringe pseudo-science. Eugenics was mainstream academic science across Europe and the United States in the early twentieth century, and Nazi race theorists cited American sterilisation laws and British and German eugenicists to give their ideas scholarly legitimacy.
Ideology alone cannot explain the timing of genocide. Antisemitic ideas had circulated for decades before 1933, which is why historians insist long-term ideology must be combined with the military and political factors covered in the following articles to explain why mass murder began specifically in 1941 and not earlier.
Paper 3 preparation
Exam technique
Paper 3: 15 marks, To what extent: "To what extent was long-term ideology, rather than wartime circumstance, responsible for the persecution and mass murder of marginalised groups in Nazi-occupied Europe?"
Build the argument: trace the line from medieval religious antisemitism through 19th-century racial pseudo-science to Hitler's synthesis in Mein Kampf, showing how each stage removed a barrier to violence , first removing the possibility of escape through conversion, then supplying state legal machinery (the Nuremberg Laws) and a bureaucratic precedent for racial killing (T4).
Evaluate perspectives: weigh the intentionalist emphasis on ideological continuity against the functionalist emphasis on wartime radicalisation, using Browning and Kershaw's synthesis to argue that long-term ideology was necessary but not sufficient on its own , it needed the military and political factors covered elsewhere in this section to become genocide.
