Across the Atlantic the first American to be considered a political psychologist was Harold Lasswell (1902–1978) whose research was also spurred by a sociological fascination of World War I. His work "Propaganda Technique in the World War" (1927) discussed the use of applying psychological theories in order to enhance propaganda technique. Lasswell moved to Europe shortly after where he started to tie Freudian and Adler personality theories to politics and published "Psychopathology and Politics" (1930). His major theories involved the motives of the politically active and the relation between propaganda and personality.
