Is it illegal to name a pig Napoleon in France?
Short answerNo; the claim appears to come from changing the pig's name to Caesar in French translations of Animal Farm.
NotesFrance has no law forbidding people from naming a pig Napoleon. The story is linked to French translations of Animal Farm, where the tyrannical pig was renamed Caesar. That publishing choice appears to have reflected concern about reception rather than a statutory ban. A translation decision then hardened into a persistent legal myth.
