Sullivan Wins Disputed Title From Dominick McCaffrey By Boxing News 24 Desk - 08/29/2026 - Comments John L. Sullivan defeated Dominick McCaffrey on August 29, 1885, in a fight now recognized as the first world heavyweight championship contested under Marquess of Queensberry rules. Boxing’s gloved era began with a disputed agreement, an illegal prizefight and seven rounds crammed into a six round contest.

The fight took place at Chester Driving Park outside Cincinnati, Ohio. Prizefighting was prohibited in the state, and Sullivan was arrested after the Law and Order League obtained a warrant. Organizers persuaded a judge that three ounce gloves and three minute rounds made the event a scientific exhibition rather than a bare knuckle prizefight.

That distinction allowed the show to proceed. It did nothing to produce an orderly championship.
