The Marquess of Queensberry was a title in the peerage of the United Kingdom, most famously associated with John Sholto Douglas, 9th Marquess of Queensberry. He is best known for his role in the development of modern boxing rules, known as the Queensberry Rules, which were established in 1867. These rules introduced the use of gloves, three-minute rounds, and a ten-count for knockdowns, significantly shaping the sport. The Marquess was also notable for his involvement in the public scandal surrounding the playwright Oscar Wilde. His opposition to Wilde's relationship with his son led to a legal battle that ultimately resulted in Wilde's imprisonment. This incident highlighted the social attitudes of the time regarding sexuality and morality.
