It was as martial as anything we do in martial arts now is. Near as I can tell, if you have belt rankings or colored sashes, it is a 'martial art', even if it has little martial application.
Indie: Sad but true!
Most of what we call martial arts now are more accurately called fighting sports/ fighting system or archaic martial arts. Taekwondo has little, if any martial (as in war) application in either the current century or the century in which it was developed. Kenjutsu had martial application at one time, but does no longer.
Indie: Taekwondo has links to Taekkyon and some of the older Korean systems, while the system itself is not an application for battle, some of the not-so-spectacular techniques do! Also I'll add that Tae Kwon Do is taught to South and North Korean Military Personnel as apart of their hand to hand combat training.
Indie: The 20th century, when Tae Kwon Do was developed by Gen Choi had little Martial (War) application, since truly the 1970's when it became more about Sport, it lost all Martial credibility. The 21st century is no different.
Boxing, prior to the introduction of Queensbury rules, was more than just punching, but nobody calls old boxing a martial art and modern boxing just a sport. Its all just the sport of boxing as practiced in different eras.
Indie: Not true, actually Boxing is a Martial Art, (I.E Combat/fighting method) unfortunately it's widely practiced as sport, but it doesn't mean it's not 'Martial'
Indie: You speak a great deal of Martial application, many of our modern militaries use Boxing as a hand2hand combat training method.
In pre-modern warfare, unarmed combat was the very last resort, and no, I do not believe or buy the crazy notion that a flying sidekick was developed to unhorse an armored and mounted rider. Pre-modern military hand to hand combat was likely similar to modern hand to hand combat: smaller technique set that was drilled with enough frequency to maintain the skill, but receiving far less attention than skills in archery and spearmanship. Most soldiers did not carry swords; these were reserved for officers, and officers, including the samurai, did not use the sword as their primary weapon on the battlefield.
Indie: Which century are we talking about? Hand2Hand combat was the primary source of war for centuries, followed by the use of weapons (I.E rocks, sticks, spears,) then (swords, metal spears,) then (firearms, cannons,) to (tanks, armory, bombs).
Indie: I'll agree that I too do not believe in the concept of a flying side kick being thrown into a riding horsemen, many of these techniques were developed solely for the purpose of entertainment and sport.
Indie: Weaponary has been the primary source of War, I'd argue that the Samurai did indeed use there sword on the battlefield as a supplement. Prior to the 18th and 19th century there were no firearms, cannons, or bombs in Japan. Archery, Spears, and Swords were the primary weapons of that time, along with hand2hand.
So how are you defining martial art? Fighting sports, such as wrestling or Taekkyeon, would not have been considered 'martial arts' by any pre-industrial military.
Indie: Again, I'd argue that any form of combat such as wrestling or Taekkyeon do have links to unarmed combat usage. Wrestling is one of the oldest forms of unarmed combat which the Greeks and Romans used in there war efforts when unarmed, surely it wasn't often though.
Indie: To answer your question about Taekkyeon and Hwarang, 1) When I was studying with a Hwarang Instructor, that was part of the studying, learning Hwarang History. 2) If you go back into Korean Lineage, you'll find where Hwarang influenced many of the techniques used in Taekkyeon. I will admit however, that many records were lost and in the Korean history there aren't accurate records of many systems.
If you mean martial art in the sense of 'fighting systems', which is how the term is used in the modern world, the definition is pretty loose.
Indie: I'll agree! Unfortunately we live in a world where many Martial art systems or 'Fighting Systems' could not hold much water in actual combat. I will add however, that many of the techniques now used in many 'fighting systems' do have lineage in actual hand2hand combat usage.
