# Eichmann in Jerusalem [[Hannah Arendt]]'s 1963 report on the trial of [[Adolf Eichmann]] — published first as a five-part *New Yorker* series — and the source of the century's most influential and most contested idea about perpetrators: the **[[Banality of Evil]]**. Watching the logistics chief of the [[Holocaust]] in his glass booth, Arendt found not a monster but a thoughtless careerist of stock phrases and institutional ambition, and drew the conclusion that the greatest evils require not demonic will but the **abdication of thinking** — ordinary people processing atrocity as workflow, as the [[Wannsee Conference]] protocol had already shown on paper. The book ignited a furor that never fully subsided, on three fronts: the banality thesis itself (sharpened by Bettina Stangneth's later *Eichmann Before Jerusalem*, which showed Eichmann's courtroom mediocrity was partly a performed defense — see [[Adolf Eichmann]] for the interpretation war); Arendt's harsh pages on the Jewish councils (*Judenräte*) forced to administer their communities' destruction, which cost her friendships and standing in the Jewish intellectual world; and her critique of the trial's political staging. It also contains her argument for what the trial *should* have asserted: that genocide is a crime against *humanity in its diversity* — committed on the body of the Jewish people — anticipating the universalist reading of [[Genocide]] law. For the KB it is a foundational text twice over: the framework for institutional complicity (the lens for every "just doing my job" actor the KB documents), and a standing lesson in how the framework can be over-applied — the cog defense is also a strategy. ## See Also - [[Banality of Evil]] — the concept's dedicated entry - [[Adolf Eichmann]] — the subject, and the post-Stangneth correction - [[The Origins of Totalitarianism]] — the earlier system-level framework - [[Hannah Arendt]] — the full diagnostic apparatus
