James Braddock vs. Joe Louis

James Braddock vs. Joe Louis was a heavyweight professional boxing fight for the undisputed heavyweight championship of the world between champion James J. Braddock and challenger Joe Louis. The fight took place on June 22, 1937 at Comiskey Park in Chicago, Illinois.
Pre-fight.
Braddock won the title by defeating Max Baer. Baer was supposed to have a rematch, but the fight never occurred. Baer instead fought Joe Louis. Louis defeated Baer, paving the way for Louis to fight Braddock for the title (although between the Baer fight and this title fight, Louis lost to Max Schmeling). This was Braddock's first and only defense and occurred over two years after winning the title.
Fight.
Louis was knocked down early in the fight, but ultimately prevailed by way of knockout in the eighth round.
Aftermath.
This fight began an unprecedented reign by Louis that included a 12-year continuous run as champion where he defeated 25 challengers, both records that still stand.
While the bout was the end of Braddock as a major boxing force, fighting only once after this fight, part of his contract with Louis was to gain a portion of Louis' earnings over the next decade.
