The Democratic People's Republic of Korea seems to have taken many, many cues from Orwell. In a bad way. Christopher Hitchens, after his visit to North Korea, described it by saying "it was as if someone had taken 1984 and said 'Can you make it as much like this as possible?'" They have even gone as far as to build a giant pyramid building. And by law, North Korean libraries may not stock books older than fifteen years — the books must be re-edited and reprinted. Wonder where they got that idea.note The most terrifying part of all of this is that it is all plausible. There are no far-fetched sci-fi elements in it, and they had 30-ish years in the book — long enough to raise a generation who've never known anything else. Orwell lifted most of Big Brother's tactics from Stalin and Hitler and provided a reason (war) for otherwise rational men and women to accept the same tactics from their own government. It also happened a lot of times in the past, in the form of how theocracies proclaimed themselves as infallible by an omnipotent god. Though this also provides some hope, as North Koreans flee to China all the time, and when the Soviet Union collapsed people lined up to leave, and they were a generation that knew nothing else.
There exists an actual political ideology known as 'National Bolshevism', whose aims include: a rigidly hierarchical society led by a small group of inner elites; the intentional stagnation of technology and culture; the creation of a totalitarian society featuring elements of Stalinism, Maoism, fascism, Nazism, and theocratic absolutism; war for the sake of destroying excess; mass murder and genocide for the sake of itself. Also, its followers wish to establish a superstate known as "Eurasia". Mercifully, it's only a small banned fringe party.
Friends and colleagues of Orwell believe that his second wife, Sonia Orwell, is to be the model for Julia. Sonia's biographer suggests that a July 1946 essay about totalitarianism that Sonia had written was the possible inspiration of Julia.
