Historic European Martial Arts (aka HEMA) is a concentration of martial studies regarding European sources. Integral sources (treatises, manuscripts, art) include Italian, German, English, Spanish, French, and more. Translations exist for much of this corpus of work & is publicly available.
People who study this martial art apply their knowledge learned from their individual groups across the world at local, national, and international tournaments.
Like any martial art, practice makes perfect and weekly classes are where you will obtain this knowledge. Without one other person at least HEMA is fairly challenging to explore. During classes expect drills (compliant and non-compliant), physical conditioning, and sparring.
