Traditional Muay Thai has a long history in Thailand as a martial art used by the military. The military style of Muay Thai is called Lerdrit, while today's "sport Muay Thai" slightly varies from the original art and uses kicks and punches in a ring and with gloves similar to those used in boxing.

Muay Thai started way back in the medieval ages when wars were fought with bows and arrows, swords, and pikes. And in hand-to-hand combat arms, legs, knees, and elbows were also used as weapons. This sport, which was included in military training, was made famous by King Nareusan 1560 A.D. During one of the many battles between Burma and Siam he was captured. The Burmese knew of his prowess as the best-unarmed fighter in the realm and gave him a chance to fight with their best for his freedom. Upon his return to Siam he was hailed as a hero and Siamese-style boxing, as it was called then, was soon recognized as a national sport. Boxing in this style reached its zenith of popularity about two hundred years ago, i.e., in the reign of Prachao Sua (King Tiger), when it was indulged in by all classes of the population.
The development of Muay Thai saw the transformation of the human body into a multifaceted weapon inspired by the weapons common to the time. The shin became the staff of the pike, used to block and strike. The arms became the raised twin swords of defense. The fist functioned as the jabbing tip of the spear. The elbow developed into the battle-axe, used to smash and to crush. The knee, too, axed its way through enemy's defenses. Finally, there was the transformation of the flashing foot into pike, arrow, and knife. As each part of the body became a weapon unto itself, a new close-combat fighting skill was born: MuayThai. Since its initial development, Muay Thai has changed in many ways. It is now a modern sport, rather than a battlefield skill. But in its heart are carried old traditions and an ancient fighting spirit.

Muay Thai is the national sport of Thailand and is widely considered to be the most realistic and practical self-defense Art.
