The Netherlands first sent athletes to the Olympic Games in 1900, and has participated in almost all Games since then with the exception of 1904 Summer Olympics in St. Louis. The Netherlands boycotted the 1956 Summer Olympics in Melbourne as a protest against the Soviet invasion in Hungary just a few weeks before the beginning of the Games (One Dutch rider competed in the 1956 equestrian events, held in Stockholm a few months before the rest of the Games).
