1957 Ice Hockey World Championships

The 1957 Ice Hockey World Championships were held between 24 February and 5 March 1957 at the Palace of Sports of the Central Lenin Stadium in Moscow, USSR. This was the last World Championships played on natural ice; and were the first World Championships held in the Soviet Union and they are remembered for the political circumstances surrounding the games. Hungary had been recently occupied by the Soviet Army (to suppress a revolution in October and November 1956), and as a result, the United States and Canada boycotted the World Championships in protest.
