Undisputed championship

An undisputed championship is a professional wrestling term for a champion who has obtained all of the major individual championships in his field during his era. The undisputed championship is an extremely rare and prestigious accomplishment.

The reported first undisputed champion was Georg Hackenschmidt, who won a series of tournaments in Europe, including a world championship tournament to win the title. Amongst the other tournaments he won were the annual major tournaments in Paris, France; Hamburg, Germany; St. Petersburg, Russia; Elberfeld, Germany; and Berlin, Germany. Hackenschmidt also defeated European Greco-Roman Champion Tom Cannon on September 4, 1902 in Liverpool, England to become the first undisputed World Heavyweight Champion.

The only other reigning champion with claim to the belt at the time was Tom Jenkins, who held the American Heavyweight Championship, which unified the American Greco-Roman Championship with the American Catch-As-Catch Can Championship. Jenkins was eventually defeated by Frank Gotch, who took over as the only man with a potentially legitimate claim to being "the true champion".

Hackenschmidt and Gotch finally met in the ring on April 3, 1908 in Chicago, Illinois. Gotch defeated Hackenschmidt to win the World Heavyweight Championship, then abandoned the American Heavyweight Championship in a process similar to today's championship unification. Gotch wrestled for several years before retiring as undisputed champion
