The Marquess of Queensberry Rules are a set of guidelines for the sport of boxing, established in 1867. Named after John Sholto Douglas, the 9th Marquess of Queensberry, these rules aimed to create a more organized and safer environment for the sport. They introduced the use of gloves, defined the length of rounds, and established the concept of a referee to oversee matches. These rules marked a significant shift from bare-knuckle fighting to modern boxing, promoting fair play and sportsmanship. The adoption of the Queensberry Rules helped to standardize boxing practices and contributed to the sport's growing popularity worldwide.
