World Heavyweight Championship Records and Statistics – Before 1921

The title recognition passed through lineage in the fights under Marquess of Queensberry Rules. The champion was informally called "the man who beat the man". The fight between John L. Sullivan and Dominick McCaffrey is recognized by many boxing historians to be for the inaugural World Heavyweight Championship under the Marquess of Queensberry Rules. The lineage was the only universally recognized form of a world championship until July 2, 1921, when Jack Dempsey became the inaugural NBA Heavyweight Champion.
