Boxing belts are a subject of constant debate. The designation of champions and contenders, a system with many belts and even more champions – it's hard to make sense of it all. We will explain it in simple terms.
Where belts came from
In the mid-19th century, a fight took place in London between boxer Benjamin Caunt and an opponent whose name is unlikely to become widely known. Caunt won by knockout, and grateful fans presented him with a red velvet belt trimmed with silver. That's where it all started.
The first belts were just symbols – there was no organization officially awarding them. Winners were recognized by newspapers, local sports commissions, and spectators. For a long time, boxing existed without a single governing body.
The first attempt to bring order occurred in the USA. In 1921, the National Boxing Association (NBA – yes, this abbreviation appeared in boxing earlier) emerged. In 1962, it was renamed the WBA (World Boxing Association). But one organization couldn't hold all of boxing, and soon there were more.
There are currently 4 main organizations:
- WBA (World Boxing Association)
- WBC (World Boxing Council)
- WBO (World Boxing Organization)
- IBF (International Boxing Federation)
WBA – the oldest organization in boxing
The World Boxing Association is the oldest of the "Big Four." The new name (renaming from NBA to WBA) appeared in 1962.
Besides its undeniable historical importance, the WBA is known for its rather creative approach to the number of its champions. Until recently, it was the organization with the largest number of champions in boxing. For years, fans argued that having 2-3 or even more world belt holders in one division was wrong. Now, the WBA has embarked on a path of reform to reduce the number of champions.
They also came up with special names for their titleholders. The WBA has a "Super Champion" – the actual, full-fledged champion – and a "Regular" champion, an analog to the "interim" world champion in other organizations. It is the latter who is the number one candidate for a fight with the "Super Champion" and who conducts the majority of defenses against contenders from the rankings.
WBC appeared later, but is still the main innovator
The World Boxing Council emerged in 1963 – and the reason for its creation was the scandals and ranking manipulation within the WBA. Initially, it included representatives from 11 countries: Argentina, Brazil, Great Britain, Venezuela, Mexico, Panama, Peru, the USA, the Philippines, France, and Chile.
It was the WBC that did one of the most important things in boxing history. In 1982, during a fight in Las Vegas, Korean Duk Koo Kim fell into a coma after a 15-round bout and died four days later without regaining consciousness. After this tragedy, the WBC was the first to reduce the number of rounds from 15 to 12. The WBA and IBF supported the initiative only five years later.
The WBC also has plenty of its own "creative" names for belts: Diamond champion, Silver champion, and there used to be a Franchise champion. And there are also special belts for individual fights. This includes the "Money Belt" for Mayweather and McGregor, encrusted with precious stones worth a million dollars. And titles for national holidays, such as the 250th anniversary of US independence. There have also been belts for specific matchups, as in the case of the meeting between Oleksandr Usyk and Tyson Fury.
Often, this is a commemorative award that carries no direct title weight. Sometimes – it is an additional award in a fight for a full championship.
IBF – one of the most principled organizations
The International Boxing Federation appeared in 1983. Bob Lee, the head of the US Boxing Association, lost the election for the post of WBA president. He didn't like this, so Bob decided to found his own organization.
At first, the IBF was not taken seriously. Then Lee came up with a brilliant move: the organization began to recognize the reigning champions of other organizations as its own champions. In particular, Larry Holmes and Marvin Hagler. Subsequently, Holmes, having quarreled with the WBC, relinquished their belt – and remained the IBF champion. Thus, the new organization gained weight.
In 1999, Bob Lee was accused of extortion and bribery to inflate rankings. His successor was Hiawatha Knight – the first female president in the history of professional boxing.
In sporting terms, the IBF is often the most principled. One champion per category. Clear requirements for belt defense. Sometimes, to the point where this principle ruins potentially interesting rematches – the IBF does not support the clause for a mandatory rematch in fight contracts. However, the system is more understandable to the general public.
WBO – the youngest organization among the top 4
The World Boxing Organization appeared in the late 1980s thanks to businessmen from Puerto Rico. For a long time, the WBC, WBA, and IBF did not recognize it as an equal. The WBA recognized the WBO only in 2004, the WBC in 2006, and the IBF in 2007.
Among those who helped the WBO become part of the mainstream were Manny Pacquiao, Naseem Hamed, and Wladimir Klitschko. It was they who gave the organization media weight.
It was only after the acceptance of the WBO as an equal that one needed to hold four titles for the status of undisputed world champion.
From two belts to four: how the concept of "undisputed champion" changed
The concept of "undisputed champion" existed long before the current four organizations – it's just that the criteria constantly changed.
When the WBC appeared in 1963, one had to have two belts: WBA and WBC. When the IBF emerged in 1983 and began to gain weight, the standard rose to three. Lennox Lewis in 1999 defeated Evander Holyfield and became the "undisputed champion" in the heavyweight division with three belts (WBA, WBC, IBF). The WBO was not counted then.
The transition to four took place in 2004. Bernard Hopkins defeated Oscar De La Hoya and collected all four belts – WBA, WBC, IBF, and WBO. This was the first time in history. And at the same time – the starting point for the WBO as a full-fledged player.
Now, an undisputed champion is one who holds all four belts simultaneously. There are fewer than two dozen of them in the entire four-belt era. Including Oleksandr Usyk, who unified the heavyweight division in 2024 by defeating Tyson Fury.
Regarding Usyk: he is a three-time undisputed champion, and his example perfectly illustrates the general system. Initially, he and Murat Gassiev each had two belts, which they unified in a joint fight – that's when Oleksandr took possession of all four titles.
Later, he collected 3 heavyweight belts, and then beat Tyson Fury, taking the WBC title from him. The IBF, as always, did not support the idea of a rematch. Therefore, Usyk vacated their belt, which Daniel Dubois and Anthony Joshua fought for. Later, Oleksandr had a rematch against Daniel, knocked him out in the 5th round, and became a three-time undisputed champion.
The Ring and Zuffa Boxing: what is happening now
Besides the four main ones, there are two more phenomena worth knowing.
The Ring magazine belt – the oldest boxing publication (founded in 1922). You can win it in three ways: defeat the current magazine champion, unify titles, or defeat the number one in The Ring rankings. The belt is considered prestigious and unofficially symbolizes the "best in the division."
Zuffa Boxing is an entirely new chapter. The company, part of the TKO Group media conglomerate (which includes the UFC and WWE), launched its own boxing promotion in 2026 and immediately announced its own championship belts. The first Zuffa Boxing belt – black and silver, with 70+ carats of diamonds – was presented in February 2026. The first championship fight was held in March: Jai Opetaia won in the cruiserweight division.
The main thing about Zuffa Boxing: they are fundamentally against cooperation with the WBC, WBA, IBF, and WBO. They want to build a completely independent system – including through amendments to the Muhammad Ali Act, without which they will not have the same rights in the US that the current authoritative organizations have. Zuffa's goal is to build a separate boxing promotion by analogy with the UFC, with their own rankings, champions, and a closed system.
