Why are most late medieval fencing manuals German?

Question

Not only is the German school dominating modern European martial arts, but almost everyone who talks about late medieval fencing refers to German fencing manuals as the primary source. Why are German fencing manuals the most well-known today? The Italian states were also well developed by that time, and Spain and France were also famous for their well-trained armies and skilled swashbucklers. However, today even martial artists form those countries refer mostly to the German manuals and use German technical terms, instead of their own. What contributed to the German school of fencing to become so dominant? Was it also dominant in its own time (Germans were used in a lot of armies as mercenaries), or is the major cause that just more books have been written (Germans did invent the printing press after all) or more books survived?

Answer 1

My guess would be the answer to which you alluded, namely, that the Germans invented the printing press and mass produced almost everything conceivable using Gutenberg's revolutionary machine. Thus the plethora of fencing instruction manuals would have been in German. Makes sense to me!
