Description In professional boxing, the middleweight division is contested above 154 lb (70 kg) and up to 160 lb (73 kg).
Early boxing history is less than exact, but the middleweight designation seems to have begun in the 1840s. In the bare-knuckle era, the first middleweight championship fight was between Tom Chandler and Dooney Harris in 1867. Chandler won, becoming known as the American middleweight champion. The first middleweight fight with gloves may have been between George Fulljames and Jack (Nonpareil) Dempsey (no relation to the more famous heavyweight Jack Dempsey).
