List of heavyweight boxing champions

Jump to: navigation, search

This is a chronological list of world heavyweight boxing champions since the introduction of the Marquess of Queensberry rules in about 1895. It does not include fights fought under Jack Broughton's rules or the London Prize Ring Rules.

Championship recognition[edit]

1885–1910[edit]

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.

List of champions[edit]

Reign began Reign ended Champion Recognition Nationality
August 29, 1885 September 7, 1892 John L. Sullivan Universal United States American
Sullivan defeated Paddy Ryan in 1882 for the bare knuckle championship of America. With the lack of legitimate challengers from outside America Sullivan gradually gained recognition as champion of the world. On August 29, 1885, he outpointed Dominick 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 United States American
James J. Corbett announced his retirement from boxing in 1895 and nominated his protégé 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.
The champions of this version of the title were:
November 11, 1895 to February 21, 1896 Peter Maher Ireland Ireland
February 21, 1896 to December 2, 1896 Bob Fitzsimmons United Kingdom Great Britain
December 2, 1896 to 1897 Tom Sharkey Ireland Ireland.
March 17, 1897 June 9, 1899 Bob Fitzsimmons Universal United Kingdom British
Fitzsimmons became an American citizen in 1898.
June 9, 1899 May 13, 19051 James J. Jeffries Universal United States 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 United States American
February 23, 1906 December 26, 1908 Tommy Burns Universal Canada Canadian
December 26, 1908 April 5, 1915 Jack Johnson Universal United States 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 United States American
July 4, 1919 September 23, 1926 Jack Dempsey Universal United States American
September 23, 1926 July 31, 19282 Gene Tunney Universal United States American
Tunney announced his retirement from professional boxing on July 31, 1928, relinquishing the championship.
June 12, 1930 January 7, 1931 Max Schmeling Universal Germany German
Schmeling defeated Jack Sharkey to earn universal recognition as champion but was stripped of the NYSAC version of the title in 1931 for refusing a rematch with Sharkey. The NYSAC title remained vacant until the two men eventually did fight in 1932.
January 7, 1931 June 21, 1932 Max Schmeling NBA & IBU Germany German
June 21, 1932 June 29, 1933 Jack Sharkey Universal United States American
June 29, 1933 June 14, 1934 Primo Carnera Universal Italy Italian
June 14, 1934 June 13, 1935 Max Baer Universal United States 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 United States American
June 22, 1937 March 1, 19492 Joe Louis Universal United States American
As of 2014, Louis still holds the record for holding the title longer than any man (11 years, 8 months and 8 days.)
June 22, 1949 September 27, 1950 Ezzard Charles NBA United States 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 United States 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 United States American
June 16, 1951 July 18, 1951 Ezzard Charles Universal United States 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.

Patterson, Tommy Jackson and reigning Light Heavyweight champion Archie Moore were matched in a three-man event to fill the title vacated by Rocky Marciano. Patterson defeated Jackson by controversial split decision on June 8, 1956, then defeated Moore to win the vacant title. After defeating Moore, Patterson would fight Jackson a second time so as to settle any perceived disputes about his legitimacy as champion, winning by TKO on July 29, 1957.
June 26, 1959 June 20, 1960 Ingemar Johansson Universal Sweden Swedish
June 20, 1960 September 25, 1962 Floyd Patterson Universal United States American

The WBA and the NYSAC withdrew their recognition of Clay (now known as Muhammad Ali) as champion for agreeing to an immediate rematch against former champion Sonny Liston, a violation of the organization's rules at the time.

Frazier and WBA champion Jimmy Ellis fought on February 16, 1970 to unify the Heavyweight championship. Frazier entered the ring recognized as the 'world champion' by several American state boxing commissions, Ellis entered as the champion recognized by the World Boxing Association, and the World Boxing Council, whose title had remained vacant following its withdrawal of recognition from Muhammad Ali, awarded championship recognition to the winner, Frazier. Frazier ultimately would defeat Ali on March 8, 1971 to assert unquestioned claim to the title. (see Fight of the Century)

March 18, 1978 September 15, 19783 Leon Spinks WBA United States American

March 18, 1978 June 9, 1978 Ken Norton WBC United States American
In an unprecedented move in the Heavyweight division, Norton was immediately recognized as the WBC's champion when Leon Spinks signed a contract to fight former champion Muhammad Ali. At the time, Norton had been designated the WBC's 'mandatory challenger' based on a victory over Jimmy Young. Upon being named champion Norton was required to defend the title against the organization's new mandatory challenger, Larry Holmes. Norton would lose that bout, and the title.
