Who was the founder of martial arts?
There really is not a good answer to this question. Regardless of what anyone else says there are many different martial arts and they do not originate from the same art or even place. There is a Buddhist monk named Bodhidharma who is generally credited with the founding of kung fu. He taught a group of monks a group of exercises to help them to get into shape so that they could meditate for longer and defend themselves. It is believed that most Asian martial arts have some connection to kung fu, so much so that it is commonly referred to as "the Grandfather of martial arts". Now the reason I say there is no good answer to this question is that not all martial arts are descendants of kung fu and a few predate it so Bodhidharma is the best answer i can give you on this but there is no absolute answer to your question.
