John "Jack" Broughton (c. 1703 – 8 January 1789) was an English bare-knuckle boxer. He was the first person to codify a set of boxing rules; prior to this the "rules" that existed were very loosely defined and tended to vary from contest to contest. His seven rules were widely used in boxing for nearly a century, until they were replaced by the London Prize Ring rules in 1838. Pierce Egan characterised Broughton as the "Father of the English School of Boxing".[1]
