Simon Byrne

Simon Byrne (1806 – 2 June 1833), nicknamed "The Emerald Gem", was an Irish bare-knuckle prize fighter. The heavyweight boxing champion of Ireland, he was drawn to England by the larger sums of prize money on offer and his hopes of becoming the heavyweight champion there as well. He became one of only six fighters ever to have been involved in fatal fights as both survivor and deceased since records began in 1741.

Byrne fought in an era when English boxing, although illegal, was patronised by many powerful individuals. Its patronage and popularity did not, however, free it from corruption, heavy betting, and staged fights. Byrne fought eight recorded matches, but accounts of his career focus on the last three, against the Scottish champion Alexander McKay, the English champion Jem Ward, and James Burke for the vacant championship of England. The injuries McKay received in his fight with Byrne resulted in his death the following day, and rioting in his home country of Scotland. Byrne went on to lose his next match against Jem Ward, which some commentators believed he was not sufficiently in condition to fight. His final contest in May 1833 was a gruelling 99 rounds against James Burke that lasted for 3 hours and 6 minutes, the longest ever recorded prize fight. Byrne died three days later as the result of damage to his brain caused by the beating he had received. Burke was arrested and tried for manslaughter but was acquitted. Following the death in 1838 of another fighter, William Phelps, also known as Brighton Bill, the London Prize Ring Rules were introduced to more clearly define the rules of prize fighting and to introduce certain safety measures, rules that still form the basis for the modern sport of boxing.

During the first half of the 19th century pugilism, better known as prize-fighting, held a curious position in British society. Although supported by members of the establishment from the royal princes downwards, it was considered illegal under the terms of the Riot Act of 1715, which defined a riot as "a tumultuous disturbance of the peace by three or more persons assembling together, of their own authority, with intent mutually to execute a violent enterprise to the terror of the people".
