There's been some discussion about why you don't need a Samurai class when the Fighter will do just fine. But it got me thinking, it's a bit odd the words martial arts are used almost exclusively to describe traditions that come from the east. Boxing is every bit the martial art that Taekwondo is. Ludwig von Liebenzell was a knight of the Teutonic Order in the 13th century, and the dude started training in the art of war at a young age. It's not like western warriors just flailed about randomly on the battlefield (okay, sometimes I'm sure they did), they were trained very often within the context of an established martial tradition.
I think it is because of genre conventions (samurai movies, kung fu movies, etc). Also the emphasis on things like Qi/Ki and the concept of meridians in many east asian martial arts. But I think something like the monk is primarily a product of the Kung Fu craze and as well as American films influenced by it. Also the ninja craze in the early 80s. Rocky doesn't translate quite the same into a class as say the 36 Chambers of Shaolin. There is a lot of very RPG friendly concepts in kung fu movies, wuxia movies, samurai movies, etc. It is a recognizable trope the way a medieval knight is a recognizable trope. Neither is all that connected to the history they are drawing on (they come out of genre)
