Jack Broughton was James Figg's most prominent student. Whilst working in Bristol as a waterman he was convinced by his future tutor to move to London and learn his trade as a fighting man. Jack excelled at Figg's academy and quickly gained a name for himself as the one of the most skilled fighters in the city. He was naturally a large man weighing 14 stone(196 pounds) but was extremely agile and reactive to attacks, by mastering the art of counter punching.
At the time boxing was bear knuckled and quite a brutal affair, generally the more aggressive the fighter the more likely they were to win. Jack Broughton brought a certain scientific methodology to the sport, outsmarting his opponents by drawing them in and punishing them with smart movements and angles, he was perhaps the first to use his opponents own aggression against him to devastating effect.
In 1741 he fought a man called George Stevenson. His opponent was beating so badly during the 35 minute contest that a few days later he died. This hugely affected Jack and his main focus from that point was to make the sport safer and do everything he could to prevent this from happening again. He drew up a set of rules named "Broughton's rules" that governed boxing from August 16, 1743 until 1838, when a new code, "The London Prize Ring Rules," was adopted. He also introduced the boxing gloves which were referred to as "mufflers". They were only used during sparring however, the sport remained bare knuckle for quite some time to come.
