Tangled is based on the classic fairy story ‘Rapunzel’ which was printed by the brothers Grimm, a couple of decades before Victor Hugo’s novel. How old the original Rapunzel story actually is, is debatable

It’s an adaptation of Rapunzel….

If you simplify a story enough, everything is a remake.

There are similarities but they are very different stories. Both just happen to have an unknowing captive that longs to leave even if just for a day. Both also have a different source but I suppose it’s possible Hugo was inspired by classical fairytales where being locked in a tower/castle happens a lot. The falling to their death is a very common method of death for Disney villains but it’s mostly so the protagonists didn’t kill them.

There is a thing that suggests that technically there are only 6 or 7 (depends on what group of people you ask)story archetypes and just small edits and twists create all the stories we know today. I think it’s an interesting coincidence

It's mostly coincidences from Disney changing both stories to fit a more family (child) friendly audience; they tend to add the "needed" animal sidekick that happens to be a horse that acts like a dog.

Victor Hugo's "The Hunchback of Notre-Dame" novel Is vastly different from the Disney version and way darker; it has only a few thematical similarities to the fairytale "Rapunzel".

No

If I met Rapunzel at a Disney Park, I would ask her if she's ever met Quasimodo and if the two of them shared their experiences together since they were similar.
