A dystopia is the opposite of a utopia (a place everyone enjoys living in), and can mean a utopia that has become corrupt. A dystopia is a place that people do not enjoy living in. A dystopia often has many problems, such as poverty, pollution, or a cruel ruler. A frequent theme is a place that is supposed to be a beautiful and perfect utopia, but where something unforeseen ruins it.
Famous examples of dystopias include George Orwell's book 1984,[1] and Aldous Huxley's book Brave New World.
