Taekwon Do - is a system of symmetrical body exercises or techniques designed for self-defense and counterattack in unarmed combat, making use of the hands and feet as weapons and defenses. However, Taekwondo is not merely a physical skill, it is also a way of thought and life. Through strict discipline, Taekwondo trains both the body and the mind placing great emphasis on the development of moral character. On other words, control of the mind, self-discipline, kindness, and humility must accompany the physical grace.
Taekwondo training consists of hardening the body through practice of the various attack and defense forms. This system of unarmed combat involves the skillful application of punching, jumping, kicking, dodging, blocking, and sparring actions; directed toward the goal of neutralizing an aggressor. Its techniques are primarily hard style kicking, punching, and
blocking, but also include the use of circular hand movements, throwing and falling techniques. An essential characteristic used in meeting an opponent's attack is the mastery of breathing and the development of jiptjung (power gathering) to unify your force.
Taekwon-Do was developed by major general Choi Hong Hi in Korea during the 1940s as partial combination of Taekkyeon and Japanese Karate.  There are two main branches of taekwondo development, although they are not mutually exclusive. Traditional taekwondo typically refers to the martial art as it was established in the 1950s and 1960s in the South Korean military, and in various civilian organizations, including schools and universities. In particular, the names and symbolism of the traditional patterns often refer to elements of Korean history, culture and religious philosophy. Traditional Taekwon-Do may refer to ITF Taekwon-Do.
Sport taekwondo has developed in the decades since the 1950s and may have a somewhat different focus, especially in terms of its emphasis on speed and competition (as in Olympic sparring). Sport taekwondo is in turn subdivided into two main styles. One style is practiced by International Taekwon-Do adherents and was created in 1955 by General Choi Hong Hi. The other style derives from Kukkiwon, the source of the sparring system sihap gyeorugi. This style is now an event at the summer Olympic Games and is governed by the World Taekwondo Federation (WTF). The Kukkiwon - or World Taekwondo Headquarters - is the traditional center for WTF taekwondo and was founded in 1973 by Dr. Kim Un Yong.
