This article introduces a new avenue for applied analysis, the depth psychology of the public as it participates in national affairs and in large group trials and issues. The public, as every individual, is a composite entity, with a diverse, even kaleidoscopic interior. It gets what it wants more than it knows and is more responsible for the outcomes of history than it acknowledges. As within an individual, unconscious factors are shown to play a leading role in influencing dramatic national events, involving conflict, repression, and irrational group behavior. The author aims to follow the role of public opinion in directing and shaping the course of a huge segment of recent history.
