Oscar De La Hoya vs. Bernard Hopkins, billed as It's History, was a professional boxing match contested on September 18, 2004 for Hopkins' WBA (Undisputed), WBC, IBF, and The Ring middleweight championships, and Oscar De La Hoya's WBO middleweight championship.

In a doubleheader event broadcast by HBO pay-per-view, Hopkins easily defeated Allen by a lopsided unanimous decision to retain his undisputed title, but De La Hoya struggled in his match with Sturm and only narrowly escaped with a unanimous decision (115–113 on all three scorecards) to capture Sturm's WBO middleweight title (becoming the first six-division champion in boxing history) and officially put his anticipated match with Hopkins on.

De La Hoya crumpled to the mat in pain and made no effort to answer the referee's 10-count as he was counted out at 1:38 of the round, giving Hopkins the knockout victory.

[6] Instead, De La Hoya took a 20-month hiatus, sitting out all of 2005, before announcing in January 2006 that he would return to fight Ricardo Mayorga for the WBC light-middleweight title in May of that year.

[7] Despite his lengthy layoff, De La Hoya dominated Mayorga en route to a sixth-round knockout victory to recapture the WBC light-middleweight title.
