Muay Thai, translated into English as Thai Boxing, is a ring fighting art and the national sport of Thailand. It is a martial art with origins in the ancient battlefield tactics of the Siamese (or Thai) army. It evolved from Krabi-Krabong, literally 'sword and baton', the hand-to-hand tactics of the Thai army. Muay Thai features punches, kicks, elbows, knees, and standing grappling. Muay Thai is one of the fastest growing fight sports in the world. Due to its popularity and effectiveness in the ring, it has become one of the most prominent arts in the Mixed Martial Arts (MMA) arena.
