Cult of personality is a pejorative term implying the concentration of all power in a single charismatic leader within a totalitarian state and the near deification of that leader in state propaganda. Totalitarian regimes use the state-controlled mass media to cultivate a larger-than-life public image of the leader through unquestioning flattery and praise. Leaders are lauded for their extraordinary courage, knowledge, wisdom, or any other superhuman quality necessary for legitimating the totalitarian regime. The cult of personality serves to sustain such a regime in power, discourage open criticism, and justify whatever political twists and turns it may decide to take.
