The darkest places in hell are reserved for those
who maintain their neutrality
in times of moral crisis.
~Dante
A cult of personality or personality cult arises when a country's leader uses mass media to create a heroic public image through unquestioning flattery and praise. Cults of personality are often found in dictatorships but can be found in some democracies. A cult of personality is similar to general hero worship except that it is created specifically for political leaders. The development of photography, sound recording, film and mass production, as well as public education and techniques used in commercial advertising, enabled political leaders to project a positive image like never before. It was with these circumstances in the 20th century that the best-known personality cults arose.
Generally, personality cults are most common in regimes with totalitarian systems of government, that seek to radically alter or transform society according to revolutionary new ideas. Often, a single leader becomes associated with this revolutionary transformation, and comes to be treated as a benevolent "guide" for the nation, without whom the transformation to a better future cannot occur. This has been generally the justification for personality cults that arose in totalitarian societies of the 20th century, such as those of Joseph Stalin and Adolf Hitler. The criticism of personality cults often focuses on the regimes of Stalin, Hitler, Mao, Ceauşescu, Saddam Hussein, Kim Il-sung and his son Kim Jong-Il. During the peak of their regimes, these leaders were presented as god-like and infallible. Their portraits were hung in homes and public buildings, with artists and poets legally required to produce only works that glorified the leader.
