What are the differences between the different Korean Styles?

[Guyver84]

I was wondering what the differences were between the Korean Styles.

What is the difference between Tang Soo Do, Tae Kwon Do, Hapkido, and Hwa Rang Do?

What are the differences between Moo Duk Kwan, Chang Do Kwan, and all the other Kwans?

Also I was watching the "Final Fu" on MTV and someone there trained in Moo Du Kwan. I haven't heard of that one. Was it supposed to be Moo Duk Kwan?

I also was told that Moo Duk Kwan was developed from Korean styles and also Chinese Tang Kung Fu and Okinawan Karate. What is the deference between the Korean styles the Tang Kung Fu and the Okinawan Karate?

I am sorry if I had a lot of questions but you cannot learn if you don't ask questions and I am also interested in the history and foundation of martial arts than just the training.

Thanks for your time and any information you can share with me.

I cannot answer all your questions, but I will answer what I can. Keep in mind this will be a WAY simplified version, and likely missing details here and there, but I am trying to keep this short.
The Taekwondo/Taekwon-Do/Tae Kwon Do was the attempt of the Korean Government to consolidate the kwans. It as only partially successful. The heads of the kwans were brought together and began to combine the knowledge of native Korean martial arts and the learned Japanese martial arts during the Japanese occupation. Moo Duk Kwan (G.M. Hwang Kee's kwan, from which your own Soo Bahk Do/Tang Soo Do came from) did not join up, nor did Hapkido. Tang Soo Do is basically a Koreanized version of Japanese Shotokan with influences of Chinese martial arts. Hapkido was a mixture of Aikijujutsu (the precursor to Aikido) and Korean kicking arts (such as TKD). It also refused to join up under the name Taekwon-Do. Hapkido features many grabs, locks, throws, and joint manipulations, though many HKD schools also incorporate strikes and kicks (like those in Taekwon-Do). I honestly know just next to nothing about Hwarang-Do save that it is named after the Hwarang warriors of ancient Korea, although I do not believe it is actually directly connected with the martial arts training they underwent. (I could be wrong, but from what I understand, just next to nothing of the old arts survived into today). I hope this helps and I am sure that others will add to this to help clarify for you. If you have further questions, I will see what I can do.

I honestly know just next to nothing about Hwarang-Do save that it is named after the Hwarang warriors of ancient Korea, although I do not believe it is actually directly connected with the martial arts training they underwent.

From what little I know, Hwa Rang Do was originally founded by Dr Joo Bang Lee (Lee, Joo Bang) in the 1960s. He claims to have learned the art from some hermit monk in the mountains named Suahm Dosa, who was supposedly one of the last remaining successors to the Hwarang warriors.

However, many share the common belief that this is a fabricated story, and that Suahm Dosa never even existed. This is mostly supported by the fact that Hwa Rang Do is in many ways similar to Hapki Yusul (Korean translation of Aiki Jujutsu), and it also shows similarities to some Chinese martial arts, as well as Taekkyon and TKD. In fact, Joo Bang Lee and his brother were two of the most skilled Korean practitioners of Dong Ryu (Daito Ryu) Hapki Yusul. However, Lee denies all similarities between HRD and HapKiYuSul.

From what I've read on the Hwa Rang Do "®" website, the style uses a bit of everything: striking, grappling, 108 (?) weapons, animal styles, round/soft and hard/linear movements, healing techniques etc. Kuk Sul Won is another art that is supposed to be similar to HRD both in technique and history.

As said above, it seems that all of the Korean martial arts you see to day are of Japanese origin, at least to a great extent.

I do Han Mu Do and from what I can see it's pretty similar to Hapkido, Kuk Sul Won and alot of Korean Martial Arts tbh.
