The history of Olympic volleyball can be traced back to the 1924 Summer Olympics in Paris, where volleyball was played as part of an American sports demonstration event. Its addition to the Olympic program, however, was given only after World War II, with the foundation of the FIVB and of some of the continental confederations. In 1957, a special tournament was held during the 53rd IOC session in Sofia, Bulgaria, to support such request. The competition was a success, and the sport was officially introduced in 1964.
