Hitler read The Crowd in Landsberg prison in 1923-24 and cited Le Bon in Mein Kampf as the definitive understanding of mass psychology. Mussolini annotated his own copy; Lenin and Trotsky read it; Freud's 1921 Group Psychology is essentially a reply. The book that every 20th-century propaganda theorist either built on or against was already 28 years old by the time the century's most successful demagogues picked it up. A founding text of modern propaganda was an 1895 French bestseller, not a state secret.
