Freudo-Marxism is a loose designation for philosophical perspectives informed by both the Marxist philosophy of Karl Marx and the psychoanalytic theory of Sigmund Freud. Its history within continental philosophy began in the 1920s and '30s and running since through critical theory, Lacanian psychoanalysis, and post-structuralism.

Wilhelm Reich was an Austrian doctor of medicine and a psychoanalyst, a member of the second generation of analysts after Sigmund Freud. The author of several influential books, The Impulsive Character (1925), The Function of the Orgasm (1927), Character Analysis (1933), and The Mass Psychology of Fascism (1933), he became one of the most radical figures in the history of psychiatry.
