List of world heavyweight boxing champions

Heavyweight World Boxing Champions since 1920

This is a chronological list of world heavyweight boxing champions since the introduction of the Marquess of Queensberry rules:

Championship recognition

1885–1910

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. 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, also in the 1990s.

1910–1961

Championship awarding organizations

• The International Boxing Union (IBU), formed in Paris in 1910. Changed name to European Boxing Union in 1946. It organised world title fights from 1913 to 1963 after which it was incorporated into the World Boxing Council (WBC).
• The New York State Athletic Commission (NYSAC), formed in 1920. It organised world title bouts until the early 1970s when it became a member of World Boxing Council (WBC).
• The National Boxing Association (NBA) formed in the USA in 1921.
• Other bodies including the National Sporting Club in Great Britain and the California State Boxing Commission awarded world titles but this did not affect the heavyweight division. tiny ballsack

1961–present

Championship awarding organizations

• The World Boxing Association (WBA), founded in 1921 as the National Boxing Association (NBA); it changed its name in 1961 and allowed membership from outside the USA.
• The World Boxing Council (WBC), founded in 1963.
• The International Boxing Federation (IBF), founded in 1983.
• The World Boxing Organization (WBO), founded in 1988.

Reign began…	Reign ended	Champion	Recognition	Nationality
August 29, 1885	September 7, 1892	John L. Sullivan	Universal	American
Sullivan defeated Paddy Ryan in 1882 for the championship recognition. On August 29, 1885, he outpointed Dominic McCaffrey in Chester Park, Cincinnati, in a bout described as being "to decide the Marquess of Queensberry glove contest for the championship of the world"
September 7, 1892	March 17, 1897	James J. Corbett	Universal	American
James J. Corbett announced his retirement from boxing in 1895 and nominated his protege Steve O'Donnell as his successor. Tradition demanded that O'Donnell win the world title in the ring so he was matched against the erratic Irish boxer Peter Maher. The bout took place at the Empire Athletic club, Maspeth, New York on 11 November, 1895, Maher surprisingly defeated O'Donnell via first round knockout. The general public had little acceptance of the new champion and even Maher himself expressed a wish to fight Corbett for the "real" title. Maher defended his "world title" against the British-born Bob Fitzsimmons in Coahuila de Zaragoza, Mexico on February 21, 1896, and was himself the victim of a first round knockout. Fitzsimmons then fought another Irish fighter, Tom Sharkey of Dundalk on December 2, 1896, in San Francisco, the bout being billed for the heavyweight title. Sharkey was awarded victory by disqualification in round 8 by the referee, Wyatt Earp. Corbett announced his return to the ring late in 1896 and the claims of Maher, Fitzsimmons (until 1897) and Sharkey to be champion are usually ignored.
March 17, 1897	June 9, 1899	Bob Fitzsimmons	Universal	British
Fitzsimmons became an American citizen in 1898.
June 9, 1899	May 13, 19051	James J. Jeffries	Universal	American
Jeffries was the first modern champion to relinquish the title, announcing his retirement and declaring that the winner of a match between Marvin Hart and Jack Root would be the next legitimate champion. Jeffries would return to the ring to face Jack Johnson.
July 3, 1905	February 23, 1906	Marvin Hart	Universal	American
February 23, 1906	December 26, 1908	Tommy Burns	Universal	Canadian
December 26, 1908	April 5, 1915	Jack Johnson	Universal	American
Jack Johnson's refusal to honor an agreement made by his manager to defend against the British champion led the National Sporting Club in London, the most powerful body in boxing outside the USA, to withdraw recognition of Johnson as champion. They matched Canadian Sam Langford and the British champion William "Iron" Hague for their version of the title. Langford beat Hague on a fourth round knockout in London on May 24, 1909. Langford returned home to America and never pressed his claim to the title.
April 5, 1915	July 4, 1919	Jess Willard	Universal	American
July 4, 1919	September 23, 1926	Jack Dempsey	Universal	American

Schmeling defeated Jack Sharkey to earn universal recognition as champion.
June 21, 1932	June 29, 1933	Jack Sharkey	Universal	American
June 29, 1933	June 14, 1934	Primo Carnera	Universal	Italian
June 14, 1934	June 13, 1935	Max Baer	Universal	American
In late 1934 the International Boxing Union ordered world champion Max Baer to defend his title against the reigning European champion, Pierre Charles of Belgium. When Baer instead opted to fight James J. Braddock they withdrew recognition of him as champion. The IBU matched Charles with the American heavyweight George Godfrey for their version of the title with the fight taking place in Brussels, Belgium on 2 October, 1935. Godfrey won a fifteen round points decision but did not press any claim to the championship and was inactive for the next two years. The IBU then recognized Baer's successor, James J. Braddock, as champion.
June 13, 1935	June 22, 1937	James J. Braddock	Universal	American
June 22, 1937	March 1, 19492	Joe Louis	Universal	American
June 22, 1949	September 27, 1950	Ezzard Charles	NBA	American
Charles won the vacant National Boxing Association championship in June 1949, but was not universally recognized as champion until June 1951.
June 6, 1950	June 16, 1951	Lee Savold	EBU	American
On the retirement of Joe Louis in March 1949, the European Boxing Union announced that a fight in May 1949 between Lee Savold of the USA and British champion Bruce Woodcock would determine their version of the world heavyweight title. The NYSAC and the British Boxing Board of Control (BBBofC) also decided to recognize the winner of the fight as their champion but it was postponed for over a year due to injuries Woodcock had suffered in a car crash. The NYSAC decided instead to recognize the winner of the upcoming bout in September 1950 between Ezzard Charles and Joe Louis as their champion. Louis was returning to the ring after an absence of 27 months. When the fight for the EBU and BBBofC world heavyweight titles eventually took place in June 1950, Savold defeated Woodcock in four rounds.
September 27, 1950	June 16, 1951	Ezzard Charles	NBA & NYSAC	American
June 16, 1951	July 18, 1951	Ezzard Charles	Universal	American
Following his defeat to Joe Louis in a non-title fight in June 1951, Lee Savold was no longer recognized as the world heavyweight champion by the EBU and the BBBofC, who both immediately transferred their recognition to Ezzard Charles. Charles therefore became universally recognized as world heavyweight champion.

June 19, 1964	February 6, 1967	Cassius Clay (Muhammad Ali)	WBC	American
March 5, 1965	February 6, 1967	Ernie Terrell	WBA & NYSAC	American
February 6, 1967	April 29, 1967	Muhammad Ali	Universal	American

April 28, 1968	February 16, 1970	Jimmy Ellis	WBA	American

March 18, 1978	June 9, 1978	Ken Norton	WBC	American
Spinks was stripped of his world title by the WBC for refusing to defend his title against their #1 ranked contender, Ken Norton. Spinks instead agreed to fight a return bout against Ali for the WBA crown. The WBC awarded Norton the title and, since he lost to Larry Holmes in his next defense, he is sometimes omitted from a list of heavyweight champions because he never won a world title fight.
June 9, 1978	December 11, 19831	Larry Holmes	WBC	American
Holmes relinquished his WBC title to assume the championship of the newly formed International Boxing Federation.
September 15, 1978	April 27, 19791	Muhammad Ali	WBA	American
Believing his career over, Ali relinquished his WBA title in exchange for a payment from promoter Don King, who was trying to stage a bout between then-WBC champ Larry Holmes and John Tate for the undisputed title. The bout never materialized, and Ali would return to the ring in 1980.

Chagaev's mandatory title defence against former champion Nicolay Valuev, scheduled for July 5, 2008, had to be cancelled for a second time after Chagaev suffered a complete tear of an Achilles tendon during his training for the fight. Because of the injury and necessary recovery time, the WBA elected to make Chagaev "Champion In Recess" and mandated that top-contenders Valuev and John Ruiz meet for the title of "Active Champion". They set a deadline of June 26, 2009, for Chagaev to fight Valuev to determine who they regard as the "Undisputed Champion".
