I don't consider it in a Victorian sense, like an apex of anything. But I think in a lot of ways it has evolved over the last fifty years more than ever before.
There have been numerous (countless) periods of radical shift and rapid change ("change" does not always equal "development") in the expression of martial arts over the centuries.
Any time there is a cultural or technological change, it hammers smack into martial arts like the hammer of Thor.
As one, tiny, example, my friends who study the period tell me that there was a radical shift in the expression of Native American Martial Arts when the Europeans introduced steel trade goods, particularly axes and knives, to what had been essentially a stone-age culture. Want to take book on whether or not introduction of steel weapons caused a greater "evolution" of martial arts than we have seen in "the last 50 years?" And that's without considering the horse in our equation.
The introduction of Roman military tactics and the effects it had on the Greek Phalanx, is another example. Or the application of Philip of Macedon and then of Alexander the Great's military tactics. Or the effects that Hannibal's War Elephants had.
The introduction of the Mine Ball created a nearly unprecedented shift.
Various legal and cultural changes create amazing shifts in the expression of martial arts as well. The Dueling culture dramatically shifted, and with it the martial arts around it, with changes in social norms associated with the practice, an in the span of a life time.
The diligent work of the Marquess of Queensberry is often thought to be the backbone of a dramatic and fundamental shift in English boxing, both leading to its eventual decriminalization in England (yes, it was, in fact, illegal despite its popularity) and the complete and utter redaction of throws, locks, and even chokes & pressure point attacks.
Or, because I mentioned the Hammer of Thor, the Norse attacks on England and Europe caused a radical shift in the martial arts there (as well as the hiring of Norse mercenaries) because the weapons and armor, as well as the average size, of the Norsemen was very different.
The change of iron and steel making technologies which allowed better European armor to be produced changed the type of swords, spears, and bludgeons along with changing techniques, tactics, and strategies.
And what are we suggesting that the current half-century period of change is based on? The re-acceptance into society of MMA & BJJ maybe? As compared to Up And Down Fighting? Or Kosen? Or Irish Faction Fights at the fair? Or are we basing it on the introduction of Asian Martial Arts to Europeans? Barton-Wright did that back in 1899 and made such a big splash that Conan Doyle wrote it into the Sherlock Holmes mythos.
No, I contest most strongly the claim that "Martial Art's have certainly evolved more in the previous 50 years than ever before." Horseshit. It is the basest of egotism to believe that the changes we have seen are anything special. It's merely the latest round.
Peace favor your sword,
