Below is a list of all the countries that are currently recognized by the International Olympic Committee as National Olympic Committees. Five countries have been represented at all Summer Olympic Games — Greece, Great Britain, France, Switzerland, and Australia, though not always as part of official teams. Switzerland is on this list even though they boycotted the Olympics - they had competed in the equestrian events several months earlier in Stockholm. France did not send a team to the Games but a lone Frenchman did compete for the USA and a mixed team. Therefore, out of these five nations only Greece has participated under its own flag in all modern summer Olympic Games.
