1984 is easily the most well-known dystopian novels, and one of the most famous science fiction novels in history (whether or not Orwell would call it science fiction). The book was written by George Orwell, and published in 1949. Almost seventy years later, the political ideas in the story are as relevant as ever, and many of the concepts have since entered everyday vernacular even when those speaking are not familiar with the book itself. .
In the future of the story, there are only three super-nations across the entire globe–Oceania (which contains the former United States and United Kingdom among others), Eurasia, and Eastasia. The three super-nations are constantly at war with another in ever-shifting alliances. The super-nations are all authoritarian states, which maintain control by a combination of ever-present surveillance, constant revision of history, and the limitation destruction of language.
