Answer:
A dystopia is a society characterized by poverty, oppression, violence, and environmental degradation. The concept of a dystopia originated in ancient Greek and Roman literature, but the term itself was coined in the mid-19th century by John Stuart Mill. Dystopian literature, which often portrays a society in which the government has become oppressive and totalitarian, began to emerge in the early 20th century with the publication of books such as "Brave New World" by Aldous Huxley and "1984" by George Orwell. Dystopian literature has had a significant influence on popular culture and has been interpreted as a commentary on contemporary society and a warning about the potential dangers of totalitarianism and other forms of social control.
