The [[World Chess Championship]] has taken various forms over time, including both [[Glossary of chess#match|match]] and [[tournament]] play. While the concept of a world champion of [[chess]] had already existed for decades, with several events considered by some to have established the world's foremost player, an event explicitly held to decide a world champion did not take place until 1886. World Championships were initially privately organized matches, with each requiring the consent of the incumbent champion to take place. After 1948, the [[International Chess Federation]] (FIDE) began organizing the Championship under its auspices. The championship was fixed to a three-year cycle, with each challenger decided by a [[Candidates Tournament]]. In 1993, the short-lived [[Professional Chess Association]] (PCA) split from FIDE, and as a result there were two competing World Championship titles between 1993 and 2006.

== Predecessor events (before 1886) ==
Chess was first introduced to Europe during the 9th century.{{sfn|Murray|1913|p=405}} In the early modern era, following the solidification of the modern [[rules of chess]], the game continued to carry consistent prestige and public interest.{{sfn|Murray|1913|pp=774–779}} While numerous players have been characterized as the game's strongest over the centuries, the idea of an international chess match or tournament did not occur until the 18th century,{{sfn|Murray|1913|p=845}} and did not materialize until the 19th century.{{sfn|Murray|1913|p=883}} While the following events did not have the title of World Champion at stake, they have been recognized—either at the time or in retrospect—as indicating the world's leading player.

== Privately organized matches (1886–1946) ==
With both [[Wilhelm Steinitz]] and [[Johannes Zukertort]] seen as plausible claimants, the two [[World Chess Championship 1886|played a match]] for the first World Championship in 1886. While Steinitz would later claim that he had been the World Champion since the 1860s, no match before 1886 was played for any formal title.{{sfn|Winter|2023a}} From then until after [[World War II]], championship matches were privately organized, and the champion was not formally obliged to face an opponent. An agreement had to be reached between the champion, the challenger, and the patrons sponsoring each match, which included providing the funds for the prize pool.{{sfn|Winter|1954|pp=9–10}} Lasker's 27-year reign as World Champion is the longest in the history of organized chess since 1886, but featured two separate 10-year spans during which he did not defend his title.

In 1946, [[Alexander Alekhine]] died while still holding the title of World Chess Champion. The [[International Chess Federation]] (FIDE), which had been founded in 1924, had been attempting to directly participate in organizing the World Championship since at least 1935. By the late 1940s, around half of the plausible contenders for the World Championship were [[Soviet]] citizens, and in 1947, the [[Soviet Chess Federation]] joined FIDE after decades of declining to do so. FIDE based the [[1948 World Chess Championship]] on the 1938 [[AVRO tournament]] that had been organized in part to select a challenger for Alekhine. The tournament ultimately featured five players, three of them Soviet citizens—including the winner, [[Mikhail Botvinnik]]. Botvinnik would go on to win or retain in four further championship matches. At the same time, FIDE established the rules for the championship going forward. It would be organized around a 3-year cycle, during which a series of [[Interzonal chess tournaments|Zonal and Interzonal tournaments]] would be held, with their highest-scoring performers invited to a [[Candidates Tournament]]. The winner of the this tournament would in turn play the champion in a match for the title. A defeated champion was entitled to a rematch the following year, after which the 3-year cycle would resume; Botvinnik benefited from this rule twice, in 1958 and 1961.<ref>{{Cite web |last=Winter |first=Edward |year=2004 |title=Interregnum |url=https://www.chesshistory.com/winter/extra/interregnum.html |archive-url=https://web.archive.org/web/20230528220053/https://www.chesshistory.com/winter/extra/interregnum.html |archive-date=28 May 2023 |access-date=15 January 2024 |website=chesshistory.com}}</ref>

With the exception of the American [[Bobby Fischer]] in 1972, Soviet citizens won every championship from 1948 until the [[dissolution of the Soviet Union]] in 1991. With the further exception of [[Viktor Korchnoi]], who had defected from the USSR in 1976, each challenger was also a Soviet citizen. Following [[World Chess Championship 1972|his victory]], Fischer never played another game organized by FIDE. Disagreements between the two parties—including Fischer insisting on a format requiring the victor to get a certain number of wins, as opposed to the number of games in a match being fixed—led to his forfeiting the title in 1975. In the absence of a match, FIDE declared [[Anatoly Karpov]], winner of the 1974 Candidates Tournament, to be the World Chess Champion by default.{{sfn|Plisetsky|Voronkov|1994|pp=363–366}}

While the issue had played a role in Fischer's forfeit, FIDE ultimately did change the match format going forward, such that the first to win 6 games would be champion.{{sfn|Plisetsky|Voronkov|1994|p=365}} Under these rules, Karpov twice defended his title against Korchnoi. The [[World Chess Championship 1984–1985|next match]]—which began in September 1984 and featured the 21-year-old [[Garry Kasparov]] as Karpov's challenger—ultimately saw 48 games played over the span of five months, with neither player able to get to 6 wins. In an unprecedented step, FIDE president [[Florencio Campomanes]] stepped in and declared the match to have ended with no result. A [[World Chess Championship 1985|new match]], which would revert to having a set number of games, was to be played later in 1985. After nearly being knocked out early in 1984, Kasparov defeated Karpov in their rematch. Over the following decade, the two would play three more championship matches, with Kasparov narrowly retaining the title in each.{{sfn|Winter|1988}}

In 1993, following [[Nigel Short]]'s victory in the Candidates Tournament, FIDE president Campomanes announced that [[1993 World Chess Championship|that year's Championship]] would take place in [[Manchester]], England. Both Kasparov and Short claimed that FIDE had made this decision without consulting either player, in violation of FIDE's regulations regarding the championship. Kasparov and Short responded by splitting from FIDE and forming the [[Professional Chess Association]] (PCA),<ref>{{Cite news |date=27 February 1993 |title=Kasparov Breaks With World Chess Body |url=https://www.nytimes.com/1993/02/27/arts/kasparov-breaks-with-world-chess-body.html |url-access=subscription |url-status=live |archive-url=https://web.archive.org/web/20180117232417/http://www.nytimes.com/1993/02/27/arts/kasparov-breaks-with-world-chess-body.html |archive-date=17 January 2018 |access-date=16 January 2024 |work=[[The New York Times]] |issn=0362-4331}}</ref> which organized a World Championship match between the two, played in London later that year. Meanwhile, FIDE stripped Kasparov of his title and organized a championship match between Karpov and [[Jan Timman]], who had finished second and third in the Candidates Tournament.<ref>{{Cite news |date=24 April 1993 |title=A Chess Title Match Is to Start on Sept. 7 |url=https://www.nytimes.com/1993/04/24/arts/a-chess-title-match-is-to-start-on-sept-7.html |url-access=subscription |url-status=live |archive-url=https://web.archive.org/web/20180117185640/http://www.nytimes.com/1993/04/24/arts/a-chess-title-match-is-to-start-on-sept-7.html |archive-date=17 January 2018 |access-date=16 January 2024 |work=The New York Times |issn=0362-4331}}</ref> For the 13 years between 1993 and 2006, there were two rival titles. While the PCA itself would fold after only a couple of years, Kasparov would retain what is referred to as "Classical" title, which would be inherited by [[Vladimir Kramnik]] upon defeating Kasparov in 2000.<ref>{{Cite news |last=McClain |first=Dylan Loeb |last2=Fleck |first2=Fiona |date=4 October 2004 |title=And They're Off, but Will Winner Be True Champion of Chess? |url=https://www.nytimes.com/2004/10/04/arts/and-theyre-off-but-will-winner-be-true-champion-of-chess.html |url-access=subscription |url-status=live |archive-url=https://web.archive.org/web/20180206121105/http://www.nytimes.com/2004/10/04/arts/and-theyre-off-but-will-winner-be-true-champion-of-chess.html |archive-date=6 February 2018 |access-date=16 January 2024 |work=The New York Times |issn=0362-4331}}</ref>

Meanwhile, FIDE once again began experimenting with the championship format. Beginning with the [[FIDE World Chess Championship 1998|1998 championship]], the system of Zonal, Interzonal, Candidates, and Championship stages was replaced with one single-elimination tournament featuring dozens of players competing for the championship. For the [[FIDE World Chess Championship 1999|next event in 1999]], the incumbent World Champion would not automatically qualify for the finals. Due to this additional change, Karpov—who had won three additional titles during the schism—declined to participate going forward. Each of the four Classical Championships retained a traditional match format.<ref>{{Cite news |last=McClain |first=Dylan Loeb |date=31 October 2000 |title=A Chess Match Is Waged for a World Title Whose Authenticity Is Challenged |url=https://www.nytimes.com/2000/10/31/world/a-chess-match-is-waged-for-a-world-title-whose-authenticity-is-challenged.html |url-access=subscription |url-status=live |archive-url=https://web.archive.org/web/20231119182159/https://www.nytimes.com/2000/10/31/world/a-chess-match-is-waged-for-a-world-title-whose-authenticity-is-challenged.html |archive-date=19 November 2023 |access-date=16 January 2024 |work=The New York Times |issn=0362-4331}}</ref>

Following a period of negotiation, in 2006 the Classical Champion [[Vladimir Kramnik]] played a match against the FIDE Champion [[Veselin Topalov]] to reunify the World Championship.{{sfn|Bareev|Levitov|2007|pp=176,324–327}} Since then, the championship has remained under the auspices of FIDE. The Candidates Tournament returned, and with the exception of the [[World Chess Championship 2007|2007 tournament]], FIDE would return to a match format for the World Championship. Instead of the previous system of Zonals and Interzonals to provide candidates, the system was redesigned around the [[Chess World Cup]].<ref>{{Cite news |date=18 December 2005 |title=Levon Aronian wins FIDE World Cup |url=https://en.chessbase.com/post/levon-aronian-wins-fide-world-cup |url-status=live |archive-url=https://web.archive.org/web/20200612102354/https://en.chessbase.com/post/levon-aronian-wins-fide-world-cup |archive-date=12 June 2020 |access-date=16 January 2024 |work=Chessbase}}</ref> Later, means for selecting candidates would variously include the [[FIDE Grand Prix]], the [[FIDE Grand Swiss Tournament]], selection by rating, and wild cards selected by the venue hosting the event.<ref>{{multiref2| {{Cite web |year=2016 |title=Rules & regulations for the Candidates Tournament of the FIDE World Championship cycle 2014–2016 |url=https://www.fide.com/FIDE/handbook/regscandidates2016.pdf |url-status=live |archive-url=https://web.archive.org/web/20200510082451/https://www.fide.com/FIDE/handbook/regscandidates2016.pdf |archive-date=10 May 2020 |access-date=16 January 2024 |publisher=International Chess Federation (FIDE)}} | {{Cite press release |date=7 January 2023 |title=FIDE reforms the qualifications paths to the Candidates Tournament |url=https://www.fide.com/news/2138 |access-date=16 January 2024 |publisher=International Chess Federation (FIDE) |archive-date=28 March 2023 |archive-url=https://web.archive.org/web/20230328122358/https://www.fide.com/news/2138 |url-status=live}} }}</ref>

While shorter matches had taken place at various points, the block of 12 classical games was much shorter than matches had been for much of the 20th century.
