The Summit Series was a series of eight ice hockey games between the Soviet Union and Canada in 1972 and 1974. The series was notable for being the first ever competition between the two countries, and for its intense rivalry. The term 'Summit Series' is derived from the talks that took place between the two sides prior to the games. The talks were held in order to discuss the rules and regulations of the series, as well as to ensure that both sides would be able to compete fairly. The talks were successful, and the series went on to become one of the most memorable sporting events of the 20th century.
