A dystopia is an imagined world or society in which people lead wretched, dehumanized, fearful lives. It is an imagined place in which everything is unpleasant or bad, typically a totalitarian or environmentally degraded one. Dystopia is widely seen as the opposite of utopia – a concept coined by Thomas More in 1516 to describe an ideal society. Both topias are common topics in fiction. Dystopia is also referred to as cacotopia or anti-utopia.
