A cult of personality arises when an individual uses mass media, propaganda, or other methods to create an idealized, heroic, and at times worshipful image, often through unquestioning flattery and praise. Sociologist Max Weber developed a tripartite classification of authority; the cult of personality holds parallels with what Weber defined as "charismatic authority". A cult of personality is similar to divinization, except that it is established by mass media and propaganda usually by the state, especially in Totalitarianism (or sometimes Authoritarianism) states.
The term "cult of personality" probably appeared in English around 1800–1850, along with the French and German use. At first it had no political connotations but was instead closely related to the Romantic "cult of genius". The political use of the phrase came first in a letter from Karl Marx to German political worker, Wilhelm Blos, 10 November 1877:
Neither of us cares a straw of popularity. Let me cite one proof of this: such was my aversion to the personality cult [orig. Personenkultus] that at the time of the International, when plagued by numerous moves [...] to accord me public honor, I never allowed one of these to enter the domain of publicity [...]
The terms "cult of personality" and "personality cult" were further popularized by Nikita Khrushchev's initially secret speech On the Cult of Personality and Its Consequences given on the final day of the 20th Congress of the Communist Party of the Soviet Union, February 25, 1956, which criticized the lionization of Josef Stalin and its contrariness to the originators of Marxist doctrine. Robert Service notes that a more accurate translation of the Russian "культ личности" ("kul't lichnosti") is the "cult of the individual".
