Boxing. Boxing is a combat sport in which two people, usually wearing protective gloves, throw punches at each other for a predetermined amount of time in a boxing ring. Amateur boxing is both an Olympic and Commonwealth Games sport and is a common fixture in most international games, it also has its own World Championships. Boxing is overseen by a referee over a series of one-to three-minute intervals called rounds. The result is decided when an opponent is deemed incapable to continue by a referee, is disqualified for breaking a rule, or resigns by throwing in a towel. If a fight completes all of its allocated rounds, the victor is determined by judges' scorecards at the end of the contest. In the event that both fighters gain equal scores from the judges, professional bouts are considered a draw. In Olympic boxing, because a winner must be declared, judges award the contest to one fighter on technical criteria. While humans have fought in hand-to-hand combat since the dawn of human history, the earliest evidence of fist-fighting sporting contests date back to the ancient Near East in the 3rd and 2nd millennia BC. The earliest evidence of boxing rules date back to Ancient Greece, where boxing was established as an Olympic game in 688 BC. Boxing evolved from 16th-and 18th-century prizefights, largely in Great Britain, to the forerunner of modern boxing in the mid-19th century with the 1867 introduction of the Marquess of Queensberry Rules. The earliest known depiction of boxing comes from a Sumerian relief in Iraq from the 3rd millennium BC. Later depictions from the 2nd millennium BC are found in reliefs from the Mesopotamian nations of Assyria and Babylonia, and in Hittite art from Asia Minor. A relief sculpture from Egyptian Thebes shows both boxers and spectators. These early Middle-Eastern and Egyptian depictions showed contests where fighters were either bare-fisted or had a band supporting the wrist. The earliest evidence of fist fighting with the use of gloves can be found on Minoan Crete. Various types of boxing existed in ancient India. The earliest references to musti-yuddha come from classical Vedic epics such as the Ramayana and Rig Veda. The Mahabharata describes two combatants boxing with clenched fists and fighting with kicks, finger strikes, knee strikes and headbutts. Duels were often fought to the death. During the period of the Western Satraps, the ruler Rudradaman-in addition to being well-versed in the great sciences which included Indian classical music, Sanskrit grammar, and logic-was said to be an excellent horseman, charioteer, elephant rider, swordsman and boxer. The Gurbilas Shemi, an 18th-century Sikh text, gives numerous references to musti-yuddha. In Ancient Greece boxing was a well developed sport and enjoyed consistent popularity. In Olympic terms, it was first introduced in the 23rd Olympiad, 688 BC. The boxers would wind leather thongs around their hands in order to protect them. There were no rounds and boxers fought until one of them acknowledged defeat or could not continue. Weight categories were not used, which meant heavyweights had a tendency to dominate. The style of boxing practiced typically featured an advanced left leg stance, with the left arm semi-extended as a guard, in addition to being used for striking, and with the right arm drawn back ready to strike. It was the head of the opponent which was primarily targeted, and there is little evidence to suggest that targeting the body was common. Boxing was a popular spectator sport in Ancient Rome. In order for the fighters to protect themselves against their opponents they wrapped leather thongs around their fists. Eventually harder leather was used and the thong soon became a weapon. The Romans even introduced metal studs to the thongs to make the cestus. Fighting events were held at Roman Amphitheatres. The Roman form of boxing was often a fight until death to please the spectators who gathered at such events. However, especially in later times, purchased slaves and trained combat performers were valuable commodities, and their lives were not given up without due consideration. Often slaves were used against one another in a circle marked on the floor.
