The 1948 World Chess Championship was a quintuple round-robin tournament played to determine the new World Chess Champion following the death of the previous champion Alexander Alekhine in 1946. The tournament marked the passing of control of the championship title to FIDE, the International Chess Federation which had been formed in 1924. The tournament was played partly in The Hague (from March 2–25), and partly in Moscow (from April 11 to May 17). 

Botvinnik (36 years old) became the sixth World Chess Champion by winning the tournament convincingly with 14 points out of 20. He also had a plus score against all the other players. Smyslov came second with 11 points, just ahead of Keres and Reshevsky on 10½. Former champion Euwe was in bad form, and finished last with 4 out of 20.
