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 This code of rules superseded the Revised London Prize Ring rules (1853), which had themselves replaced the original London Prize Ring rules (1743) of Jack Broughton.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).
In March 1895 the Marquess was sued for defamatory libel by Oscar Wilde, who Douglas had intimated was a "somdomite" (sic): Douglas made the accusation because he was angered over Wilde's relationship with his son, Alfred. Soon after the trial opened, the libel case was withdrawn, but Wilde was later convicted of gross indecency under the Criminal Law Amendment Act of 1895.
Douglas died in London. He had married the daughter of Alfred Montgomery, and his title passed to his son Percy Sholto Douglas.
