This book critically analyzes the mechanisms of Nazi propaganda between 1920 and 1933, focusing on how language, emotion, and repetition were orchestrated to shape public opinion and legitimize ideology. Through the study of speeches by Hitler, Goebbels, and other key figures, as well as visual and textual materials from the period, the work identifies core propaganda principles: simplicity, saturation, repetition, and the construction of enemies. With a linguistic approach and careful source selection, Startari reveals how Nazi rhetoric played a central role in fostering ideological alignment and mass support for the regime. This interdisciplinary analysis—combining history, discourse theory, and semiotics—offers valuable insight into the political function of language and the modern dangers of ideological manipulation. Maquinaria de Propaganda remains highly relevant for understanding the enduring power of persuasion in contemporary mass communication.
