So we have these Alternate Universe
USA tropes: the Divided States of America
where the US never unified or the union broke up at some point, the Fallen States of America
where the US has become a third world country and the Expanded States of America
where the US has gotten bigger. But what about when fiction presents the idea of the US either losing the Revolutionary War or it never happening? You have a modern day America under British rule.
Due to a lot of this fiction coming from US authors, this is almost always depicted as a bad, bad, thing. Which can make other audiences, particularly British, uncomfortable at times.
- Sliders: At least one episode had the cast slide to an Alternate Universe where the US was under British control and George Washington had been executed as a traitor. Members of the cast then tell a member of the royal family after rescuing him that "Why don't you give democracy a go?" as though he should never have heard of it... despite the United Kingdom having been a Constitutional Monarchy and Parliamentary Democracy since 1688 so he'd know what democracy is.
- Code Geass has an interesting case: the revolutionary war was lost, but then Britain lost to Napoleon Bonaparte, and therefore no longer has control over the British Isles, themselves making the seat of the Britannian Empire be physically in the US.
- Tunnel Through the Deeps is a book by Harry Harrison in which, due to the fact it was John Cabot, not Christopher Columbus, who discovered North America, Spain was also never unified and unable to fund Columbus. This lead to a scenario where the revolutionary war was lost and George Washington was shot as a traitor. The main character is a descendant of Washington who feels tarred by his family's bad reputation whilst working on a transatlantic tunnel between the British Isles and the Northern American colonies.
- The Fairly OddParents had "Twistory", which eventually got banned from airing on Nickelodeon as it was considered to take the anti-British sentiment a bit too far. Timmy wishes the founding fathers to appear in his tree house to help him with a history report. Their removal from history, however, turns the US back into a British colony. Everyone gets bad teeth, all the houses of Dimmsdale turn into tudor thatched room cottages (despite construction being very past that point by 1772 in the UK) and there is no electricity due to Ben Franklin never discovering it -- completely in ignorance of the discoveries in the fields of electromagnetism by the Englishman Michael Faraday. Timmy then has to go back in time to stop Benedict Arnold from convincing the revolutionaries to surrender.
