This chapter asks: why is it that right-wing authoritarian populism in recent times has become much more popular than left-wing movements? How do right-wing authoritarian movements communicate? Why is it that right-wing political communication strategies seem to garner and result in mass support? The critical theory of authoritarianism advanced by the Frankfurt School and related authors on fascism, Nazism, and the authoritarian personality help us to critically analyse the communication of authoritarianism. In this context, particularly the works by Franz Leopold Neumann, Erich Fromm, Theodor W. Adorno, Herbert Marcuse, Leo Löwenthal, and Willhelm Reich are relevant.
