Everything that has been said here is certainly true. It's nice to know how arts were developed and what they were developed for. It's also nice to know who trained with who, when, under what circumstances, etc.
However, as a student of Korean Martial arts, KMA practitioners tend to get very caught up in history. I study Kuk Sool. I did not establish the art yet I am called on to admit that the Grandmaster trained with this guy, stole this from this guy, establish where the Grandmaster was on Tuesday, and for me, that's not what I got into martial arts for nor is it my job to defend the art. Does the history add to the study? Sure, but I'm not going to stop studying KSW because the history is unclear. I have good instructors, I enjoy the art, and I like the syllabus and that's what keeps me going.
I am at the point now where I don't get involved in history discussions anymore. I want to train. If the history is clearer does it make the training better. No, those are just words. History doesn't help you defend yourself, increase your health, or calm your mind.
This isn't the kind of history I actually had in mind, jkn.
Here's the kind of thing I was thinking of. We know, about as well as we can know anything, that Japan occupied Korea in notoriously brutal fashion after the terms of the Russo-Japanese War were worked out, and one of the first things they did was institute a series of security measures against the Koreans in order to suppress any resistance or chance of rebellion from the notoriously independent citizenry. That included suppression of any indigenous MAs (which, so far as we can tell based on what little documentation there is, was largely derivative from Chinese systems; see Stanley Henning's 2000
Journal of Asian Martial Arts article for detailed evidence on this point). For a number of years at the beginning of the occupation, Japanese MAs, particularly jiujitsu, had been taught in Japan, but in the 1920s even those arts were forcibly suppressed, and very thorough the Japanese were about it, too! So in the 1920s and 1930s, what little MA training was available in Korea was Japanese, and even that died out. The only route available to Koreans to study MAs was therefore to go to Japan itself and study, which
was permitted. The young men who went to Japan to study were therefore virtually without any prior MA background (for a discussion of this point, see Dakin Burdick's 1997
JAMA article `People and Events of Taekwondo's Formative Years', or the somewhat different later paper under the same name at
www.budosportcapelle.nl/gesch.html, for documentation and discussion). When these young men, now trained MAists, returned to Korea at the end of the 1930s, they were therefore trained
almost exclusively in various Japanese versions of Okinawan karate. That is what the overwhelming message of the historical record shows.
So why is this historical background important to understanding the technical content of the art? Because it means that the technical content that the Kwan founders brought back from Japan is essentially the same technical content as Shotokan, Shudokan and, in the case of the system that Hwang Kee taught, very likely Japanese Goju-ryu (for some discussion of this point, see the exchange
here). Which explains why it is that the early hyungs of TKD were identical to Japanse karate kata, and why it is that the subsequent replacement of those kata in the TKD syllabus by more `nativized' versions, which didn't look quite so obviously Japanese, was technically largely irrelevant—because all that happened was that various subsequences of the kata were rearranged, transposed, or `shuffled'; but the content of these later hyungs, the Palgwes, and even the Taegeuks, was indistinguishable in almost every respect to the Japanese kata that the Kwan founders had learned. Which means that the fighting methods encoded in the Japanese kata are still present in the hyungs, and that the methods for deciphering and decoding those applications are applicable in the same way to the hyungs that they are to kata.
What makes us think that such applications actually are present in the kata themselves? Again, knowing the history of karate, we know that Anko Itosu deliberately concealed the actual purpose of the moves of the kata he taught when he was packaging them for use in the Okinawan public schools. There is extensive discussion of this and related points in the thread that starts
here); the crucial point is that the
kaisai no genri—the general method of deciphering kata for hard, realistic combat applications, not the kind of children's-story bunkai that Itosu and his colleagues propagated as simple block-kick-punch apps—has become the object of intense research by a network of karateka, based mostly in the UK but with US and Australian `branches' as well, and there are now a number of detailed analyses of rules for recovering the fighting content of kata, which KMAists like Simon O'Neil and Stuart Anslow have applied to TKD very convincingly in a number of publications. The message of history here then is that
(i) KMA striking arts as
fighting systems (not point-scoring dueling competitions) are virtually entirely based in their technical content on Japanese karate;
(ii) Japanese karate kata yield brutally effective street-ready combat systems when studied from the point of view of the 19th c. Okinawan karate founders whose kata subcomponents show up almost completely unaltered in TKD and TSD forms;
(iii) therefore, the methods and conclusions of the analysts who have exhibited, and `field-tested' under realistic conditions, the combat applications of the subcomponents of Japanese kata are directly applicable to TKD hyungs, which are for the most part nothing but rearrangements of these same Japanese kata subcomponents. This means that the techs you can learn from TKD hyungs to terminate a violent street attack are going to be substantially identical to those recoverable from TKD hyungs, using the same rules of decoding and interpretation.
So you can understand I hope that I have to disagree pretty much completely with your statement that
If the history is clearer does it make the training better[?] No, those are just words. History doesn't help you defend yourself...
I think that the preceding makes it clear that knowing the history of TKD, where it came, can give you a very different perspective on the actual practice and combat effectiveness of the art. And I think this is going to be true in general—just as knowing how Okinawan karate came about historically gives one a much better picture of the depth of its technical content in terms of non-striking moves (locks, pins, sweeps, takedowns and various other components missing from much modern thinking about what kind of an art karate is). This is what I was getting at when I suggested in my OP that there is a significant link between the history of an art and its technical content and application...
