Not quite /lit/ but you guys are good at English.
Why does "years" in the following have an apostrophe?
https://en.wikipedia.org/wiki/Hundred_Years'_War
https://en.wikipedia.org/wiki/Thirty_Years'_War
Does the war belong to the thirty years? It certainly isn't a contraction of "year is".

I really don't know but maybe the og construction is "the war of 100 years"
>War of a hundred years -> Hundred years' War
is how it would've happened IMO
but it's a convention more than anything else
