Dystopian fiction explores the social and political structure of an often futuristic society that is both repressive and controlling. These dystopian states often disguise themselves as a utopia with an authoritarian or totalitarian form of government. Excessive social control, repression of individual liberty and freedom and mass poverty are common themes.
