. Men and women of any age are eligible to contest this title.

The official world championship is generally regarded to have begun in 1886, when the two leading players in Europe, Wilhelm Steinitz and Johann Zukertort, played a match. From 1886 to 1946, the champion set the terms, requiring any challenger to raise a sizable stake and defeat the champion in a match in order to become the new world champion. From 1948 to 1993, the championship was administered by FIDE, the world chess federation. In 1993, the reigning champion (Garry Kasparov

History

The concept of a world chess champion started to emerge in the first half of the nineteenth century, and the phrase "world champion" appeared in 1845. From this time onwards various players were acclaimed as world champions, but the first contest that was defined in advance as being for the world championship was the match between Steinitz

 in 1886. Until 1948 world championship contests were matches arranged privately between the players. As a result the players also had to arrange the funding, in the form of stakes provided by enthusiasts who wished to bet on one of the players. In the early twentieth century this was sometimes a barrier that prevented or delayed challenges for the title.

Between 1888 and 1948 various difficulties that arose in match negotiations led players to try to define agreed rules for matches, including the frequency of matches, how much or how little say the champion had in the conditions for a title match and what the stakes and division of the purse should be. However these attempts were unsuccessful in practise, as the same issues continued to delay or prevent challenges.

The first attempt by an external organization to manage the world championship was in 1887–1889, but this experiment was not repeated. A system for managing regular contests for the title went into operation in 1948, under the control of FIDE, and functioned quite smoothly until 1993. However in that year reigning champion Kasparov

Official champions before FIDE (1886–1946)

The championship was conducted on a fairly informal basis through the remainder of the nineteenth century and in the first half of the twentieth: if a player thought he was strong enough, he (or his friends) would find financial backing for a match purse and challenge the reigning world champion. If he won, he would become the new champion. There was no formal system of qualification.

(6 March 1879) argued that Steinitz had forfeited the title by prolonged absence from competitive chess and therefore Zukertort should be regarded as champion. The Chess Player's Chronicle (18 July 1883) made a more complex argument: other commentators had suggested that Zukertort should be regarded as champion because he had won a major tournament (London 1883, 3 points ahead of Steinitz); the Chronicle thought tournaments were an unreliable way of deciding the championship and Steinitz' victories in matches gave him the better claim; but, if Zukertort were the champion, he should forfeit the title if he declined a challenge, especially from a challenger with Steinitz' credentials, and in that case the title should revert to Steinitz.

The third prize-winner Isidore Gunsberg was prepared to play Steinitz for the title in New York, and Steinitz won their match in 1890–1891. This experiment was not repeated and the 1894 match in which Steinitz lost his title was a private arrangement between the players.

Lasker (1894–1920)

Lasker was the first champion after Steinitz; although he did not defend his title in 1897–1906 or 1911–1920, he did string together an impressive run of tournament victories and dominated his opponents. His success was largely due to the fact that he was an excellent practical player. In difficult or objectively lost positions he would complicate matters and use his extraordinary tactical abilities to save the game. He held the title from 1894 to 1921, the longest reign (27 years) of any champion. In that period he defended the title successfully in one-sided matches against Steinitz, Frank Marshall, Siegbert Tarrasch

 and, in addition to making severe financial demands, proposed some novel conditions: the match should be considered drawn if neither player finished with a 2-game lead; and it should have a maximum of 30 games, but finish if either player won 6 games and had a 2-game lead (previous matches had been won by the first to win a certain number of games, usually 10; in theory such a match might go on for ever). Capablanca objected to the 2-game lead clause; Lasker took offence at the terms in which Capablanca criticized the 2-game lead condition and broke off negotiations.

Further controversy arose when, in 1912, Lasker's terms for a proposed match with Akiba Rubinstein

On 27 June 1920 Lasker abdicated in favor of Capablanca because of public criticisms of the terms for the match, naming Capablanca as his successor (American Chess Bulletin, July August 1920).

Capablanca, Alekhine and Euwe (1921–46)

Capablanca was the last and greatest of the "natural" players: he prepared little for his games, but won them brilliantly. He possessed an astonishing insight into positions simply by glancing at them. Renowned for his ability to gradually convert the tiniest advantages into victory as well as his famous endgame skill, Capablanca was one of the most feared players in history, and once went undefeated for eight years (1916 to 1924).

After the breakdown of his first attempt to negotiate a title match against Lasker (1911), Capablanca drafted rules for the conduct of future challenges, which were agreed by the other top players at the 1914 Saint Petersburg tournament, including Lasker, and approved at the Mannheim Congress later that year. The main points were: the champion must be prepared to defend his title once a year; the match should be won by whichever player first won six or eight games (the champion had the right to choose); and the stake should be at least £1,000 (worth about £347,000 or $700,000 in 2006 terms).

Following the controversies surrounding his 1921 match against Lasker, in 1922 world champion Capablanca proposed the "London Rules": the first player to win six games would win the match; playing sessions would be limited to 5 hours; the time limit would be 40 moves in 2½ hours; the champion must defend his title within one year of receiving a challenge from a recognized master; the champion would decide the date of the match; the champion was not obliged to accept a challenge for a purse of less than US $10,000 (worth about $349,000 in 2006 terms); 20% of the purse was to be paid to the title holder, and the remainder being divided, 60% going to the winner of the match, and 40% to the loser; the highest purse bid must be accepted.

n, but Alekhine overcame Capablanca's natural skill with his unmatched drive and extensive preparation (especially deep opening analysis, which became a hallmark of all future grandmasters). The aggressive Alekhine was helped by his fearsome tactical skill, which complicated the game.

Immediately after winning, Alekhine announced that he was willing to grant Capablanca a return match provided Capablanca met the requirements of the "London Rules". Negotiations dragged on for several years, often breaking down when agreement seemed in sight. Alekhine easily won two title matches against Efim Bogoljubov in 1929

 agreed to place future matches for the world title under the auspices of FIDE, except that he would only play Capablanca under the same conditions that governed their match in 1927. Although FIDE wished to set up a "unification" match between Alekhine and Bogoljubow, it made little progress and the title "Champion of FIDE" quietly vanished after Alekhine won the 1929 world championship match that he and Bogoljubow themselves arranged.

While negotiating his 1937 World Championship re-match with Alekhine, Euwe proposed that if he retained the title FIDE should manage the nomination of future challengers and the conduct of championship matches. FIDE had been trying since 1935 to introduce rules on how to select challengers, and its various proposals favored selection by some sort of committee. While they were debating procedures in 1937 and Alekhine and Euwe were preparing for their re-match later that year, the Dutch Chess Federation proposed that a super-tournament (AVRO) of ex-champions and rising stars should be held to select the next challenger. FIDE rejected this proposal and at their second attempt nominated Salo Flohr

, who had lost the title to Alekhine in 1927; if Euwe lost his title to Capablanca then FIDE's decision should be followed and Capablanca would have to play Flohr in 1940.

While this confusion went unresolved: Euwe lost his title to Alekhine; the AVRO tournament

 that made the normal procedure impossible. The situation was very confused, with many respected players and commentators offering different solutions. FIDE found it very difficult to organize the early discussions on how to resolve the interregnum because problems with money and travel so soon after the end of World War II prevented many countries from sending representatives. The shortage of clear information resulted in otherwise responsible magazines publishing rumors and speculation, which only made the situation more confused.
It did not help that the Soviet Union had long refused to join FIDE, and by this time it was clear that about half the credible contenders were Soviet citizens. But the Soviet Union realized it could not afford to be left out of the discussions about the vacant world championship, and in 1947 sent a telegram apologizing for the absence of Soviet representatives and requesting that the USSR be represented in future FIDE Committees.
The eventual solution was very similar to FIDE's initial proposal and to a proposal put forward by the Soviet Union (authored by Mikhail Botvinnik

, so only five players competed. Botvinnik won convincingly and thus became world champion, ending the interregnum.

Since Keres lost his first four games against Botvinnik in the 1948 World Championship Tournament, suspicions are sometimes raised that Keres was forced to "throw" games to allow Botvinnik to win the Championship. Chess historian Taylor Kingston investigated all the available evidence and arguments, and concluded that: Soviet chess officials gave Keres strong hints that he should not hinder Botvinnik's attempt to win the World Championship; Botvinnik only discovered this about half-way through the tournament and protested so strongly that he angered Soviet officials; Keres probably did not deliberately lose games to Botvinnik or anyone else in the tournament.

The proposals which led to the 1948 Championship Tournament also specified the procedure by which challengers for the World Championship would be selected in a 3-year cycle: countries affiliated to FIDE would send players to Zonal Tournaments (the number varied depending on how many good enough players each country had); the players who gained the top places in these would compete in an Interzonal Tournament (later split into two and then three tournaments as the number of countries and eligible players increased); the highest-placed players from the Interzonal would compete in the Candidates Tournament

Soviet dominance (1948–1972)

Alekhine's death threw the chess world into chaos. The previous informal system could not deal with this unlikely eventuality. Though Euwe had some claim to the title, he allowed FIDE to step in. Though FIDE had existed since 1924, it lacked power because the strongest chess-playing nation, the Soviet Union, refused to participate. However, upon Alekhine's death, the Soviet Union joined FIDE in order to be a part of the process to select the next champion. FIDE organised a match tournament in 1948

It is said he perfected the game as a science, not a sport, through his emphasis on technique over tactics. This longevity is even more impressive considering he had hit his peak during World War II, during which international chess was suspended, and he was the first champion who was forced to play all his challengers. Perhaps most remarkably, he was not a professional chess player, but a decorated engineer by trade.

, and Tigran Petrosian (the first two by the previously unheard-of scores of 6–0), Fischer easily qualified to challenge Spassky. The so-called Match of the Century, possibly the most famous in chess history, had a shaky start: having lost the first game, Fischer defaulted the second after he failed to turn up, complaining about playing conditions. There was concern he would default the whole match rather than play, but he duly turned up for the third game and won it brilliantly. Spassky won only one more game in the rest of the match and was eventually well beaten by Fischer by a score of 12.5 – 8.5.

 in the final candidates match, winning by a score of 12.5–11.5. Fischer objected to the "best of 24 games" championship match format that had been used from 1951 onwards, claiming that it would encourage whoever got an early lead to play for draws. Instead he demanded that the match should be won by whoever first won 10 games, except that if the score reached 9–9 he should remain champion. He argued that this was more advantageous to the challenger than the champion's advantage under the existing system, where the champion retained the title if the match was tied at 12–12 including draws. Eventually FIDE deposed Fischer and crowned Karpov as the new champion.

By 2002, not only were there two rival champions, but Kasparov's strong results – he had the top Elo rating in the world and had won a string of major tournaments after losing his title in 2000 – ensured even more confusion over who was World Champion. So in May 2002, American grandmaster Yasser Seirawan led the organisation of the so-called "Prague Agreement" to reunite the world championship. Kramnik had organised a candidates tournament (won later in 2002 by Peter Leko

However, the matches proved difficult to finance and organise. The Kramnik-Leko match

Meanwhile, FIDE never managed to organise a Kasparov match, either with 2002 FIDE champion Ponomariov, or 2004 FIDE champion Kasimdzhanov. Partly due to his frustration at the situation, Kasparov retired from chess in 2005, still ranked #1 in the world.
