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 supervised 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, resigns by throwing in a towel, or is pronounced the winner or loser based on the judges' scorecards at the end of the contest. In the event that both fighters gain equal scores from the judges, the fight is considered a draw-what in other sports would be referred to as a tie-(professional boxing). In Olympic boxing, due to the fact that a winner must be declared, in the case of a draw - the judges use technical criteria to choose the most deserving winner of the bout.
While humans have fought in hand-to-hand combat since before the dawn of history, the earliest evidence of fist-fighting sporting contests date back to the ancient Middle East in the 3rd and 2nd millennia BCE. 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 BCE. 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 (c. 1350 BCE) shows both boxers and spectators. The earliest evidence for fist fighting with any kind of gloves can be found on Minoan Crete (c. 1500–1400 BCE).
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 themselves. 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 which then led to a more sinister weapon called the myrmex ('limb piercer'). 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. This is where the term ring came from. In AD 393, during the Roman gladiator period, boxing was abolished due to excessive brutality. It was not until the late 16th century that boxing re-surfaced in London.
Records of Classical boxing activity disappeared after the fall of the Western Roman Empire when the wearing of weapons became common once again and interest in fighting with the fists waned. However, there are detailed records of various fist-fighting sports that were maintained in different cities and provinces of Italy between the 12th and 17th centuries. There was also a sport in ancient Rus called Kulachniy Boy or "Fist Fighting".
As the wearing of swords became less common, there was renewed interest in fencing with the fists. The sport would later resurface in England during the early 16th century in the form of bare-knuckle boxing sometimes referred to as prizefighting. The first documented account of a bare-knuckle fight in England appeared in 1681 in the London Protestant Mercury, and the first English bare-knuckle champion was James Figg in 1719. This is also the time when the word "boxing" first came to be used. This earliest form of modern boxing was very different. Contests in Mr. Figg's time, in addition to fist fighting, also contained fencing and cudgeling. On 6 January 1681, the first recorded boxing match took place in Britain when Christopher Monck, 2nd Duke of Albemarle (and later Lieutenant Governor of Jamaica) engineered a bout between his butler and his butcher with the latter winning the prize.
