Switzerland has sent athletes to compete in every Olympic Games since it first participated in the inaugural 1896 Summer Olympics in Athens. Switzerland boycotted the main events of the 1956 Summer Olympics held in Melbourne, joining several other nations in protest of the Soviet Union's invasion of Hungary, due the Hungarian Uprising. However, Swiss athletes did take part in the equestrian events, which were held earlier that year in Stockholm, Sweden, due to Australian quarantine laws. Notably, the Swiss dressage team earned a bronze medal in those competitions.
