Boxing, sport, both amateur and professional, involving attack and defense with the fists. Boxers usually wear padded gloves and generally observe the code set forth in the marquess of Queensberry rules. Matched in weight and ability, boxing contestants try to land blows hard and often with their fists, each attempting to avoid the blows of the opponent. A boxer wins a match either by outscoring the opponent—points can be tallied in several ways—or by rendering the opponent incapable of continuing the match. Bouts range from 3 to 12 rounds, each round normally lasting three minutes.

Professional organizations

World professional boxing has no one controlling body that is universally recognized. This situation had its origins in the United States in 1920 when two organizations were established: the National Boxing Association, a private body, and the New York State Athletic Commission, a state agency. Divided control led to competing organizations’ sometimes recognizing different boxers as world champions at the same time.

During the 19th and again at the beginning of the 20th century, the popularity of boxing brought about the formation of weight divisions other than the heavyweight class to eliminate the handicap of smaller contestants’ having to concede excessive weight to their opponents. Some of these weight divisions originated in the United States, others in Great Britain.

There were traditionally eight weight divisions in men’s boxing. More divisions were added, and professional governing bodies now recognize a total of 17 weight classes, which had their current names established by the major boxing organizations in 2015.
