Undisputed championship (boxing)
In boxing, the undisputed champion of a weight class is the boxer who simultaneously holds world titles from all recognized major organisations by each other and the International Boxing Hall of Fame. There are currently four major sanctioning bodies: WBA, WBC, IBF and WBO. There were many undisputed champions before the number of major sanctioning bodies recognizing each other increased to four in 2007, but there have only been 19 boxers to hold all four titles simultaneously.
Wladimir Klitschko won the unified championship in 2008 and defended it 14 times
Muhammad Ali defended the unified/undisputed heavyweight championship 10 times; the record was unbeaten for 36 years
