Orwell wrote 1984 just after World War II ended, wanting it to serve as a warning to his readers. He wanted to be certain that the kind of future presented in the novel should never come to pass, even though the practices that contribute to the development of such a state were abundantly present in Orwell's time.
Orwell lived during a time in which tyranny was a reality in Spain, Germany, the Soviet Union, and other countries, where government kept an iron fist (or curtain) around its citizens, where there was little, if any freedom, and where hunger, forced labor, and mass execution were common.
Orwell espoused democratic socialism. In his essay, "Why I Write," published in 1947, two years before the publication of 1984, Orwell stated that he writes, among other reasons, from the "[d]esire to push the world in a certain direction, to alter other peoples' idea of the kind of society that they should strive after." Orwell used his writing to express his powerful political feelings, and that fact is readily apparent in the society he creates in 1984.
