Marquess of Queensberry rules
The Marquess of Queensberry rules are a code of popularly accepted rules in the sport of boxing. They were named so because John Sholto Douglas, the 9th Marquess of Queensberry publicly endorsed the code.
The boxing code was written by John Graham Chambers in 1865 and published in 1867 as "the Queensberry rules for the sport of boxing". This code of rules superseded the Revised London Prize Ring rules (1853), which had themselves replaced the original London Prize Ring rules (1743) of Jack Broughton. 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" (17, sect. 5, pt. 1).
The first prize fight under Marquess of Queensberry rules took place in Cincinnati, Ohio August 29th 1885. John L. Sullivan defeated his opponent,
