The Marquess of Queensberry rules is 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 boxing gloves in boxing.
The title Duke of Queensberry was created in the Peerage of Scotland on 3 February 1684 along with the subsidiary title Marquess of Dumfriesshire for the 1st Marquess of Queensberry.
 The Dukedom was held along with the Marquessate of Queensberry until the death of the 4th Duke (and 5th Marquess) in 1810, when the Marquessate was inherited by Sir Charles Douglas of Kelhead, 5th Baronet, while the Dukedom was inherited by the 3rd Duke of Buccleuch.
 Since then the title of Duke of Queensberry has been held by the Dukes of Buccleuch.

This is a list of lineal boxing world champions.
 An official list of lineal champions in professional boxing is maintained by the Cyber Boxing Zone (CBZ) website, with input from boxing historian Tracy Callis of the International Boxing Research Organization.
 These were first published in 1994, and are retrospective to the introduction of the Queensberry Rules in 1885.
 The Transnational Boxing Rankings Board, which promotes the concept of one world champion per weight class, hands out the most complete version of the lineal championship and is recognized by CBZ for maintaining the list of genuine lineal world champions.

The London Prize Ring Rules was a list of boxing rules promulgated in 1838 and revised in 1853.
 These rules were based on those drafted by England's Jack Broughton in 1743 and governed the conduct of prizefighting/bare-knuckle boxing for over 100 years.
 They "introduced measures that remain in effect for professional boxing to this day, such as outlawing butting, gouging, scratching, kicking, hitting a man while down, holding the ropes, and using resin, stones or hard objects in the hands, and biting."
 They were later superseded by the Marquess of Queensberry rules, the origins of the modern sport of boxing.
