Yes. Ingsoc.

There are three “sacred principles” of INGSOC. They are Newspeak, as described above, doublethink, and the mutability (or changeability) of the past. The Party attempts to control what its citizens are thinking through all three of these means. With doublethink, Orwell stated that it is “to be conscious of complete truthfulness while telling carefully constructed lies” and “to hold simultaneously two opinions which” one knows to be contradictory but believing them both. It’s a paradox that allows the Party to do anything it wants, including changing who Oceania is at war with without the majority of the citizens noticing. For example, the narrator says that:
At this moment, for example, in 1984 (if it was1984), Oceania was at war with Eurasia and in alliance with Eastasia. In no public or private utterance was it ever admitted that the three powers had at any time been grouped along different lines.
Winston knows that it was “only four years since Oceania had been at war with Eastasia and in an alliance with Eurasia.” But, as is the case with doublethink, “that was merely a piece of furtive knowledge which he happened to possess because his memory was not satisfactorily under control.”
