The Marquess of Queensberry Rules are a code of generally accepted rules in the sport of boxing. Drafted in London in 1865 and published in 1867, they were named so as John Douglas, 9th Marquess of Queensberry publicly endorsed the code, although they were written by a Welsh sportsman named John Graham Chambers. The code of rules on which modern boxing is based, the Queensberry rules were the first to mandate the use of gloves in boxing.
The Queensberry Rules eventually superseded the London Prize Ring Rules (revised in 1853), and are intended for use in both professional and amateur boxing matches, thus separating it from the less-popular American Fair Play Rules, which were strictly intended for amateur matches. In popular culture the term is sometimes used to refer to a sense of sportsmanship and fair play.
The boxing code was written by John Graham Chambers, a Welshman, and drafted in London in 1865, before being published in 1867 as "the Queensberry rules for the sport of boxing". At the time, boxing matches were conducted under the London Prize Ring Rules, written in 1838 and revised in 1853. Bare-knuckle fights under the London Prize Rules continued for the next several decades, although the Queensberry Rules would eventually become the standard set of rules under which all boxing matches were governed. This version persuaded boxers that "you must not fight simply to win; no holds barred is not the way; you must win by the rules".
One early prize fighter who fought under Marquess of Queensberry rules was Jem Mace, former English heavyweight champion, who defeated Bill Davis in Virginia City, Nevada under these rules in 1876. In 1889, the Queensberry rules came into use in the United States and Canada.
Current modern rules per the Association of Boxing Commissions are as follows.
A boxing match consists of a determined number of three-minute rounds, a total of up to 12 rounds (formerly 15). A minute is typically spent between each round with the fighters in their assigned corners receiving advice and attention from their coaches. The fight is controlled by a referee who works in the ring to judge and control the fight, rule on the ability of the fighters to fight safely, count knocked-down fighters, and rule on fouls.
