The present article is an attempt to apply the Freudian psychoanalysis to the study of terrorist organizations. It uses Freud's teachings to explore the unconscious nature and the motivational mechanisms of the adepts of terrorism and the impulses (i.e. the “drives”) for accepting and obeying the organizational frameworks. It starts with a brief description of the key differences between terrorist groups and other organizations in the matters of the presence of the “life” and “death” drives, which it further applies to the analysis of the terrorist groups from the point of view of their collective social unconscious. It resumes with the overview of the intra-organizational psychodynamics of terrorism with the ultimate discussion on what makes terrorist groups so attractive to their potential followers across different regions and cultures.
