World heavyweight boxing championship records and statistics

Below is a list of world heavyweight boxing championship records and statistics.

Championship recognitionEdit

As per International Boxing Hall Of Fame:[1]

1884–1921Edit

  • Champions were recognized by public acclamation. A champion in that era was a fighter who had a notable win over another fighter and kept winning afterward. It was a lineal championship. The only way to win the championship was to beat the current champion. Retirements or disputed results could lead to a championship being split among several men for periods of time. With only minor exceptions, the heavyweight division remained free from dual title-holders until the 1960s. For an early example, see the 1896 World Heavyweight Championship.

Sanctioning organizations: 1921–presentEdit

Gradually, the role of recognizing champions in the division evolved into a more formal affair, with public acclamation being supplemented (or in some cases, contradicted) by recognition by one or more athletic commissions, sanctioning organizations, or a combination of them. The most notable examples with respect to the heavyweight division have included:

  • The New York State Athletic Commission (NYSAC). A governmental entity initially formed for the purpose of regulating boxing in the State of New York, thanks to New York's place as the epicenter of boxing from the 1930s through 1950s, the NYSAC expanded its reach to sanctioning championship bouts. This practice continued until, like the IBU, the NYSAC became a member of the WBC.
  • The National Boxing Association (NBA) was organized in 1921. In 1962, the organization was renamed the World Boxing Association (WBA).
  • The WBC was organized in 1963.
  • The IBF, which was founded in 1983 by the members of the United States Boxing Association after the USBA withdrew from membership in the WBA.
  • The WBO, which was founded in 1989 by disgruntled members of the WBC.

There are also titles that aren't considered major but play a significant role in legitimizing the heavyweight champion:

  • The Ring began awarding championship belts in 1922, stopped giving belts to world champions in the 1990s, then reintroduced their title in 2002, and ignored the current ongoing world championship lineage. Under the original version of the policy, you could win the title by either defeating the reigning champion or winning a box-off between the magazine's No. 1 and No. 2 (occasionally No. 3) ranked contenders. A fighter could not be stripped of the title unless he lost or retired. Since May 2012, under the new policy, The Ring title can be awarded when the No. 1 and No. 2 contenders face each other or when either of them faces No. 3, No. 4 or No. 5 contender. In addition, the title can be taken away by losing the fight, not scheduling a fight for 18 months, not scheduling a fight with a top 5 contender for two years, or retiring.[2]

Statistics by eraEdit

Before 1921Edit

At the very beginnings, before the establishment of the sanctioning organizations, the title recognition passed through lineage in the fights under Marquess of Queensberry Rules. The champion was informally called "the man who beat the man". The fight between John L. Sullivan and Dominick McCaffrey is recognized by many boxing historians, including those at The Ring, to be for the inaugural World Heavyweight Championship under the Marquess of Queensberry Rules (however, some dispute that claim for various reasons, including the short distance of the bout, McCaffrey's small size and the fact that both fighters were Americans).[64] The lineage was the only universally recognized form of a world championship until July 2, 1921, when Jack Dempsey became the inaugural NBA Heavyweight Champion.

  Jess Willard April 5, 1915 – July 4, 1919 [33]

National sanctioning bodiesEdit

The growing popularity of boxing led to a birth of various regional sanctioning organizations, with each recognizing their own champion. The major governing bodies were the National Boxing Association, formed in 1921, the New York State Athletic Commission, found after the Walker Law legalized prizefighting in New York in 1920, and the International Boxing Union, created in 1911 in Paris in an attempt create a unified international governing body for professional boxing. The NBA and NYSAC both made then-lineal champion Jack Dempsey their inaugural champion on July 2, 1921, and July 24, 1922, respectively.[65]

International expansionEdit

First international expansionEdit

The growing popularity of boxing outside of the USA led to creation of various boxing organizations, each strengthening their influence (most notably the British Boxing Board of Control (BBBofC)) and having their own champion. This resulted in a growing number of boxers claiming to be legitimate champions. The disruption in boxing was solved after the World War II when the World Championship Committee (WCC) was created with NBA as its unanimous authority. The committee, however, was disbanded in 1955 when NBA, along with its new members (which included the Orient, Mexican and South American federations and boxing commissions of the Philippines and Thailand) left WCC citing lack of control over the organisation. The NBA's voting scheme guaranteed one vote for each state commission as well as one vote for each foreign country.[67][68] On August 23, 1962, the NBA officially became the WBA and moved their headquarters to Panama City, Panama.

Second international expansionEdit

A year later NYSAC along with European Boxing Union (EBU) and BBBofC supported creation of the WBC. WBC was officially established on February 14, 1963, in Mexico City, Mexico by 11 countries (the United States, Puerto Rico, Argentina, United Kingdom, France, Mexico, Philippines, Panama, Chile, Peru, Venezuela and Brazil) that were invited by the President of Mexico Adolfo López Mateos to form an international organization to unify all commissions of the world to control the expansion of boxing.[69] The reason for the move were concerns about WBA's alleged lack of desire to support professional boxing outside of the USA.[70] In April 1983, members of United States Boxing Association (USBA) along with Robert W. Lee (a former WBA vice-president) voted to expand the organisation and form the USBA-International. The organization later changed the name to IBF.[71] The inaugural IBF heavyweight champion was Larry Holmes, who relinquished the WBC title to accept IBF's recognition, thus helping the newly formed organization to establish its legitimacy. Another major sanctioning body, the WBO, was established in 1988 in San Juan, Puerto Rico by a group of local businessmen. At the beginnings, when most of the challengers for WBA, WBC and IBF titles were Americans, WBO had a wider variety of countries, mainly European, represented in title bouts. In the inaugural bout, Italian boxer Francesco Damiani defeated Johnny du Plooy from South Africa by KO in the 3rd round. Before the Klitschko Era, United Kingdom tied USA for most wins in WBO heavyweight title fights with 8.[72] WBO struggled with receiving credibility at first, but by the beginning of the 2000s, the WBA was giving the same recognition to WBO champions as it did to WBC and IBF champions.

WBA, WBC, IBF, and WBO are all recognized as major boxing organizations by each other and the International Boxing Hall of Fame. Riddick Bowe and Tyson Fury are the only heavyweight boxers to win all four world titles (though neither held all four simultaneously), while Vitali and Wladimir Klitschko are the only brothers to hold them at the same time (from 2011 to 2013). Wladimir is the only unified champion to successfully defend the title against the same opponent twice (Tony Thompson in 2008 and 2012).
