Taekwondo is a defensive martial art which has been developed independent of external influences in Korea throughout a period spanning almost two millennia and is practiced widely throughout the world. The history of the sport goes back as far back as the ancient Goguryeo (or Koguryo) dynasty which ruled over the northern parts of the Korean Peninsula. Taekwondo is almost the oldest martial art in the world. The initial reason for its creation was to defend against the wild animals and bandits who were rife in the region. Taekwondo training generally includes a system of kicks thrown from a mobile stance. In general, taekwondo is meant for self-defense and spiritual development. It plays a significant role in boosting one's self-confidence. Individuals who are self-confident behave humbly and with tolerance towards those who are not. The main feature of taekwondo is the fact that it is a martial art which consists of defense techniques applied with bare hands and feet against an opponent. Taekwondo training consists of four disciplines, namely: Poomse (patterns), Hyung, Gyoroogi (sparring) and Kyukpa (board breaking test). Hyung is important since it consists of fundamental technical principles, physical culture movements, fundamental technique practices and team practice. Tae means "to strike or break with foot"; kwon "to strike or break with fist" and do means "way", "method", or "art". A practitioner who does not respect the rules of do and engages in this sport only as a martial art shall never be considered as a taekwondoïste no matter how powerful or flexible his or her hand or foot kicks are. Without do, practitioners who are inflexible and violent in character might imposed their wills on individuals they do not like by using the techniques they have learnt. It is only through the do that taekwondoïstes can develop their characters, learn to be patient and increase their stamina.
