It seems to me that many countries (ethnicities?) ha a traditional self defense martial art. France has Savate. Here is a link to more
List of 180+ Martial Arts Styles - Black Belt Wiki.
It also seems to me that the family of unarmed martial arts that started in India mover to China moved to Okinawa and then Japan and eventually the world which I will collectively refer to as "family of Karate" has spread more widely than most of the others on the above list.
Why has the one group been so successful at expanding world wide, While the others on the list are mostly localized? Or am I way off base on my understanding of the unarmed self defense world?
Thanks.
I would say there are four main reasons (short answer version), each one leading to the next.
1. While there are many countries that have a self-defense art linked to them and
may be said to be "traditional," very few of them are deeply
cultural, reflective of that country's history and philosophical belief system to the extent the Oriental systems are. As such, they have evolved a richer tapestry and wider range of benefits to offer the public.
2. In the case of karate, its practice was
institutionalized, being mandated to be taught in the public schools as not just self-defense, but as exercise, a self-development discipline and an expression of nationalism, ingraining it further into the culture. It wasn't just an "underground" activity as other country's MA were. It was visible.
3.
American military presence in Japan/Okinawa was the first big step in introducing karate to the West. Bored soldiers with time and energy to spare were attracted to the art's physical aspects. A few karate masters contracted with the military to teach Marines and other branches on base, exposing many to the art.
4. These military men brought karate back to the USA and opened karate schools. Karate became widely disseminated, getting a foothold with the American public who were also fascinated with culture. Widespread
commercialization soon followed, Westerners embracing karate's uniqueness and benefits. Kung fu, TKD, ninjitsu, and other arts tagged along. Oriental martial artists emigrated to the US (to escape their war torn home) and opened schools as well. Movies and TV jumped in, competitive karate as a sport grew and the rest is history.
No other region's MA had the qualities and the mechanism of popularization karate (and the Oriental arts that followed) did.
