Propaganda Technique in the World War

Harold Lasswell's Propaganda Technique in the World War (1927) is a foundational analysis of the propaganda campaigns used by major nations during World War I. The book examines the methods and strategies employed to influence public opinion and behavior during wartime. Lasswell's work contributed to the burgeoning field of propaganda studies, which sought to understand the psychological and social mechanisms behind persuasive communication.12

The study of propaganda evolved significantly in the 20th century, particularly with the rise of mass media and marketing techniques. Researchers began investigating consumer behavior and responses to advertising, which later extended to political campaigns. Lasswell's research, alongside that of other social scientists, helped move the study of propaganda from anecdotal observation toward a more scientific approach, analyzing the techniques, media, and effects of persuasive messaging.13
