Was the sword the main weapon during the 1400s?

yes it was due to lack of money in Europe at the time. another reason was that

muskets and hand-cannons were at a few and only royal guard, dukes, lords and kings would have them. sWords were also more common because of the accuaracy which bows could not garentee during the late middle ages and the reniassance. it was only in china,japan,Mongolia and Middle East including Asia minor (turkey) where they hardly use sWords even then 20 to 30,000 soldiers out of a possible 70,00 would carry them.
