Moo Duk Kwan Taekwondo, founded in the mid-20th century by Hwang Kee, is deeply rooted in various ancestral martial arts. The formation of Moo Duk Kwan was influenced primarily by the following traditions:

1. Taekkyeon: This is a traditional Korean martial art characterized by its fluid, rhythmic movements and emphasis on footwork. Taekkyeon techniques include dynamic kicks and strikes, which can be seen in the kicking techniques of Moo Duk Kwan.

2. Hwa Rang Do: This martial art has historical ties to the Hwa Rang youth group during the Silla Dynasty. It incorporates various fighting techniques and philosophies, emphasizing discipline and moral development.

3. Karate: Hwang Kee studied karate in Japan, and its influence is evident in the striking techniques, stances, and forms (hyung) used in Moo Duk Kwan. The incorporation of karate techniques helped shape the early curriculum of Moo Duk Kwan.

4. Chinese Martial Arts: Elements from Chinese martial arts also contributed to Moo Duk Kwan, particularly in its forms and philosophical underpinnings, reflecting a blend of various Asian martial traditions.

5. Korean Folk Wrestling (Ssireum): Although not directly a striking art, the grappling techniques from Ssireum influenced the self-defense aspects of Moo Duk Kwan.

Moo Duk Kwan emphasizes not only physical techniques but also the development of character, discipline, and respect, which are core principles derived from these ancestral arts. The combination of these influences has led to the unique style and philosophy that Moo Duk Kwan embodies today.
