undisputed champions WBC IBF WBA WBO?

BHop

 

Hopkins and Taylor

That's the entire list.

Of course, there were plenty who held all but the WBO from back when the WBO was a pretty fringy title.

 

We have a winner.

 

Apart from the WBO Roy Jones Jr pretty muh owned everything at Light Heavy

WBC, WBA, IBF, IBO, IBA, WBF

 

Hopkins and Taylor are the only one that come to mind. An impressive feat.

 

Calzaghe had all 4 but not at the same time, he relinquised one he got from lacy at some point then got the others from kessler

 

It takes so long to get the titles. I doubt Sturm would have fought Hopkins anytime soon but De La Hoya stole it from him and gave it to hopkins.

 

At the moment 160 is the only division that has a direct and easy to trace lineage back to all 4 major titles.

 

wasnt tyson undisputed?

 

Undisputed traditionally means WBA, WBC and IBF.

 

Yes indeed, WBO was not as recognized as it is today. IBO today was WBO at that time. So Tyson held all the meaningful belts. But today, fighters are undisputed when they hold 3 of the 4 major belts.

Sometimes a fighter could be called undisputed when he is the best fighter in his own division. BHop for example was regarded as the undisputed LHW when he defeated Tarver. Tarver was the champ after beating Jones and Johnson, he was the top dog at that time and Bhop took him to school!!

 

True, but before that it was only WBA and WBC.
Today WBO is one of the "majors", so you have to count it.

 

Hopkins was the first and only one to unify and defend all 4 titles (of course several others unified all when there were 3 and 2). Taylor took it from BHop but never defended all, Calzaghe captured all but didn't hold at the same time (was stripped of the IBF before the Kessler fight). If Mormeck hadn't been stripped Haye could've unified all 4 vs. Macca but it didn't happen.

Yet Dariusz Michalczewski was the legitimate lineal LHW champion.
