Muay Thai or Thai Boxing was born on the battlefields of the 15th century, during the legendary clashes between Thai (or Siamese) armies and their bitter rivals, the Burmese. Trained in the weapons-based fighting method known as Krabi Krabong, these early Thai soldiers also became famous for their toughness in close-quarters weaponless combat, where legs, knees, elbows and hands took the place of swords and sticks.
