The Summer Olympic Games or the Games of the Olympiad are an international multi-sport event, occurring every four years, organized by the International Olympic Committee. Medals are awarded in each event, with gold medals for first place, silver for second and bronze for third, a tradition that started in 1904. The Winter Olympics were also created due to the success of the summer Olympics.

The olympics have increased from a 42-event competition with fewer than 250 male athletes to a 300-event sporting celebration with over 10,000 competitors from 205 nations. Organizers for the 2008 Summer Olympics in Beijing expected approximately 10,500 athletes to take part in the 302 events on the program for the games.

The United States has hosted four Summer Olympics Games, more than any other nation. The United Kingdom will have hosted three Summer Olympics Games when they return to the British capital in 2012, all of them have been (and will be) in London, making it the first city to hold the Summer Olympic Games three times. Australia, France, Germany and Greece have all hosted the Summer Olympic Games twice. Other countries that have hosted the summer Olympics are Belgium, China, Canada, Finland, Italy, Japan, Mexico, Netherlands, South Korea, Spain, the Soviet Union and Sweden. In the 2016 Summer Olympics, Rio de Janeiro will host the first Summer Games in South America. Four cities have hosted two Summer Olympic Games: Los Angeles, London, Paris and Athens. Stockholm, Sweden, has hosted events at two Summer Olympic Games, having hosted the games in 1912 and the equestrian events at the 1956 Summer Olympics—which they are usually listed as jointly hosting. Events at the summer Olympics have also been held in Hong Kong and the Netherlands (both represented by their own NOCs), with the equestrian events at the 2008 Summer Olympics being held in Hong Kong and two sailing races at the 1920 Summer Olympics being held in the Netherlands.

The 1992 Summer Olympic Games, officially known as the Games of the XXV Olympiad, were an international multi-sport event celebrated in Barcelona, Spain, in 1992. The International Olympic Committee voted in 1986 to separate the Summer and Winter Games, which had been held in the same year since 1924, and place them in alternating even-numbered years, beginning in 1994. The 1992 Summer Games were the last to be staged in the same year as the Winter Games. Due to the end of the Cold War, these games were the first without boycotts since 1972.

Barcelona, the birthplace of then-IOC president Juan Antonio Samaranch, was selected over Amsterdam, Belgrade, Birmingham, Brisbane and Paris in Lausanne, Switzerland, on October 17, 1986, during the 91st IOC Session. It had bid for the 1936 Summer Olympics, losing out to Berlin.

169 nations sent athletes to compete in these Games (the number of competitors for each country below is given in brackets). With the dissolution of the Soviet Union, twelve states formed a Unified Team, while the Baltic States of Estonia, Latvia and Lithuania had their own teams. For the first time, Croatia, Slovenia and Bosnia-Herzegovina competed as independent nations after separation from Socialist Yugoslavia. Federal Republic of Yugoslavia was banned due to UN sanctions, but individual Yugoslav athletes were allowed to take part as Independent Olympic Participants. It was also the first Olympics since 1964 that a unified Germany competed at the Olympics. This was the Olympic debut for Namibia and the unified team of Yemen, after several separate participations of North and South Yemen. South Africa returned to the Games after 32 years. Four National Olympic Committees didn't send their athletes to compete: Afghanistan, Brunei, Liberia and Somalia.
