Aladdin, the best-known of the tales in the Arabian Nights, is not an authentic folk tale — it was written and inserted into the book by its French translator, Antoine Galland, in 1709.

Galland said that he’d heard the story from a Syrian monk, but there’s no precedent for it in the Arabic tradition — the story was unknown until Galland published it.
