The middleweight division, from 154 to 160 lbs, has long been one of the most popular in professional boxing. The origins of the weight class can be traced back to the 1840s during the bare-knuckle era of the sport. Gennady ‘Triple G’ Golovkin is regarded as the best middleweight in the world at the moment and that’s backed up by the numerous titles he holds.
Some of the greatest boxers in history have fought as middleweights including Jake LaMotta, Sugar Ray Robinson, Carmen Basilio, Dick Tiger, Emile Griffith, Carlos Monzon, Marvin Hagler, Roberto Duran, Sugar Ray Leonard, Tommy Hearns, Felix Trinidad, Roy Jones Jr., Oscar De La Hoya and Bernard Hopkins.
This list consists of the 10 longest single reigns in the weight division in one or more of the sport’s governing bodies such as the IBF, WBA, WBC, WBO, and IBO. If a boxer was champion more than one time then his longest reign is considered rather than combined reigns as middleweight champ.
10. Arthur Abraham
Armenian-born Arthur Abraham has boxed out of Germany since turning pro in 2003. He won the vacant IBF Middleweight Championship by stopping Kingsley Ikeke in the fifth round in 2005. Abraham then defended his title 11 times and reigned for three years, seven months and two days. The 11 title defenses are the fourth-most in the middleweight division. His toughest opponents over that stretch were Raul Marquez and Edison Miranda, whom he beat twice. Abraham wanted to unify the middleweight titles, but couldn’t land a fight with any of the other champs so moved up to the 168 lb. super middleweight division. He managed to beat Jermain Taylor, but lost to Andre Dirrell, Carl Froch and Andre Ward at the heavier weight before winning the WBO Super Middleweight Title from Robert Stieglitz. Abraham defended it once then lost to Stieglitz in a rematch. But by March, 2014 he was champ once again after beating Stieglitz in their rubber match. Abraham defended his title five times, including a fourth bout with Stieglitz, but lost the belt to Gilberto Ramirez in April, 2016. The 37-year-old Abraham (46-5, 30 Kos) is scheduled to take on Chris Eubank Jr. for the IBO Super Middleweight Championship on July 15th.
