Has 'undisputed' always meant four belts? When did the four-belt era begin?
There was of course a time when weight classes had one world champion, and that was it. The sport eventually ended up with two recognised titles, then three, and now four.
Here's a brief timeline of the changes:
- 1922–1963, a boxer who held both the NYSAC and NBA (WBA) world titles simultaneously
- 1963–1983, a boxer who held both the WBA and WBC world titles simultaneously
- 1983–2007, a boxer who held the WBA, WBC, and IBF world titles simultaneously
- 2007–present, a boxer who holds the WBA, WBC, IBF and WBO world titles simultaneously
So, the 'four-belt' era began in 2007, but fighters of yesteryear including Muhammad Ali, Mike Tyson, Evander Holyfield, Lennox Lewis, Rocky Marciano, Roy Jones Jr. and more are nonetheless former undisputed champions of the world.
Who will be the next undisputed champion?
The next undisputed champion will be crowned on July 20 in Dallas when Katie Taylor and Amanda Serrano meet for Taylor's undisputed women's lightweight title.
This is a rematch of their fight in April 2022 when Taylor beat Serrano by split decision in a contest which was a candidate for fight of the year.
Does 'The Ring' championship count towards undisputed?
No. For now, The Ring magazine's version of the title, while a prestigious title, remains outside of the criteria. Because of its attempts to stick to the lineal timeline of titleholders (you have to beat the champion to be the champion) for the most part, it nonetheless remains a coveted belt by most fighters.
