History
The boxing code was written by John Graham Chambers in London 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 This code of rules superseded the Revised London Prize Ring rules (1853), which had themselves replaced the original London Prize Ring rules (1743) of Jack Broughton.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).
One early prize fighter who fought under Marquess of Queensberry rules was Jem Mace, who won the English heavyweight title under these rules in 1861. In 1889, the Queensberry rules came into use in the United States and Canada.
