No, the Rapiers are European, same as "longswords" and such. They are from a rather different time period than the usual mediaeval range that D&D settings tend to depict however.
By different area I meant a different area of Europe. Europe seems a bit large for everywhere to have gotten the rapier at the same time. I meant different area I. The same way for my follow-up question. Was there a nearby country that had their own special weapon which could be a replacement for the rapier, or a possible seafaring country that made use of such a weapon which could be the origin of the d8 finesse-able weapon for this country?
