Understanding the difference between unified and undisputed champions in boxing

In boxing, a unified champion holds two or more of the four major titles: WBC, WBA, IBF, and WBO. Currently, there are 13 unified champions, including heavyweight Oleksandr Usyk. An undisputed champion holds all four major belts simultaneously, a rare achievement in the four-belt era. Only nine male boxers have reached this status since 2004, with Usyk being the first undisputed heavyweight champion of this era. Undisputed champions often lose their titles quickly due to boxing politics. Despite this, the title of undisputed champion remains highly coveted among fighters.
