John Sholto Douglas, the Marquess of Queensberry, was a Scottish nobleman born on March 20, 1844. He is best known for his association with the sport of boxing, as he established the Queensberry Rules in 1867. These rules helped to standardize the sport, introducing concepts such as three-minute rounds and the use of gloves. Queensberry was also notable for his involvement in the trial of Oscar Wilde, a famous playwright. His public accusations against Wilde led to a scandal that ultimately resulted in Wilde's imprisonment. The Marquess's actions had a significant impact on both boxing and literary history.
