The practice dates back at least to Ancient Greece, but rules for such bare-fisted fighting began to be formulated in the 18th century, when a Jack Broughton began to apply rules to make contests both safer and fairer.
Tom Cribb was one of the most notable bare-knuckle boxers of the early 19th century. Less than 100 years later, the practice had all but disappeared, replaced by much more regulated gloved bouts.
