Bare-knuckle boxing (also known as bare-knuckle, prizefighting, fist fight or fisticuffs) is the original form of boxing, closely related to ancient combat sports. It involves two individuals fighting without boxing gloves or other padding on their hands. The difference between street fighting and a bare-knuckle boxing match is that the latter has an accepted set of rules, such as not striking a downed opponent. The rules that provided the foundation for bare-knuckle boxing for much of the 18th and 19th centuries were the London Prize Ring Rules.
