Flyweight

Flyweight is a class in boxing which includes fighters weighing less than 112 lb (51 kg) but above 108 lb (49 kg).

The flyweight division was the last of boxing's eight traditional weight classes to be established. Before 1909, anyone below featherweight was considered a bantamweight, regardless of how small the boxer. In 1911, the organization that eventually became the British Boxing Board of Control held a match that crowned Sid Smith as the first flyweight champion of the world. Jimmy Wilde, who reigned from 1914 to 1923, was the first fighter recognized both in Britain and the United States as a flyweight champion.[1]

Other notable flyweights include Pancho Villa, Walter McGowan, Pascual Pérez, Pone Kingpetch, Miguel Canto, Dave McAuley, Mark "Too Sharp" Johnson, Manny Pacquiao, Jorge Arce, Vic Darchinyan and Nonito Donaire.
