The Summer Olympic Games, also known as the Games of the Olympiad, and often referred to as the Summer Olympics, is a major international multi-sport event normally held once every four years on leap years. The inaugural Games took place in 1896 in Athens, Greece, and the most recent Games were held in 2021 in Tokyo, Japan. The International Olympic Committee (IOC) is responsible for organising the Games and for overseeing the host city's preparations. The tradition of awarding medals began in 1904; in each Olympic event, gold medals are awarded for first place, silver medals for second place, and bronze medals for third place.
The Winter Olympic Games were created out of the success of the Summer Olympic Games, which are regarded as the largest and most prestigious multi-sport international event in the world.
The 1896 Summer Olympics, officially known as the Games of the I Olympiad and commonly known as Athens 1896, was the first international Olympic Games held in modern history. Organised by the International Olympic Committee (IOC), which had been created by French aristocrat Pierre de Coubertin, it was held in Athens, Greece, from 6 to 15 April 1896.
At the 1896 Summer Olympics, two tennis events were contested, both for men. They began on 8 April and continued on 9 April, 10 April, and 11 April. 13 or 15 competitors from six nations, including seven Greeks, took part in the tennis competition. Many of the doubles teams were of mixed nationality, including all three medalist pairs. None of the leading players of the time such as Wimbledon champion Harold Mahony, U.S champion Robert Wrenn, William Larned or Wilfred Baddeley participated. To strengthen the field, the organization added sportsmen from other Olympic events, including weightlifter Momčilo Tapavica, hammer thrower George S. Robertson and 800-metres runners Edwin Flack and Friedrich Traun.
At the 1896 Summer Olympics, the first modern Olympiad, twelve athletics events were contested. A total of 25 medals were awarded. The medals were later denoted as 37 modern medals. All of the events except the marathon were held in the Panathinaiko Stadium, which was also the finish for the marathon. Events were held on 6 April, 7 April, 9 April, and 10 April 1896. Altogether, 63 athletes, all men, from nine nations competed. This made athletics the most international of the nine sports at the 1896 Games.
The 1906 Intercalated Games or 1906 Olympic Games was an international multi-sport event that was celebrated in Athens, Greece. They were at the time considered to be Olympic Games and were referred to as the "Second International Olympic Games in Athens" by the International Olympic Committee. However, the medals that were distributed to the participants during these games are not officially recognised by the Olympic Committee and are not displayed with the collection of Olympic medals at the Olympic Museum in Lausanne, Switzerland.
The 1900 Summer Olympics, today officially known as the Games of the II Olympiad and also known as Paris 1900, were an international multi-sport event that took place in Paris, France, from 14 May to 28 October 1900. No opening or closing ceremonies were held. They were the very first Summer Olympics ever held in a non-leap year until the 2020 Summer Olympics, which were delayed to 2021 due to the COVID-19 Pandemic.
The 2004 Summer Paralympics, the 12th Summer Paralympic Games, were a major international multi-sport event for athletes with disabilities governed by the International Paralympic Committee, held in Athens, Greece from 17 to 28 September 2004. 3,808 athletes from 136 countries participated. During these games 304 World Records were broken with 448 Paralympic Games Records being broken across 19 different sports. 8,863 volunteers worked along the Organizing Committee.
An Olympic medal is awarded to successful competitors at one of the Olympic Games. There are three classes of medal to be won: gold, silver, and bronze, awarded to first, second, and third place, respectively. The granting of awards is laid out in detail in the Olympic protocols.
The 2004 Summer Olympics, officially known as the Games of the XXVIII Olympiad, were a summer multi-sport event held in Athens, the capital city of Greece, from 13 to 29 August 2004. A total of 10,625 athletes from 201 countries represented by National Olympic Committees participated in these games, competing in 301 events in 28 sports. Kiribati and Timor Leste competed for the first time in these Olympic Games.
Belarus competed at the 2004 Summer Olympics in Athens, Greece, from 13 to 29 August 2004. This was the nation's fifth appearance at the Summer Olympics in the post-Soviet era. The Belarus Olympic Committee sent a total of 151 athletes to the Games, 82 men and 69 women, to compete in 22 sports.
The 1908 Summer Olympics was an international multi-sport event held from 27 April to 31 October 1908, in London, United Kingdom, coinciding with the Franco-British Exhibition.

Australia competed at the 1896 Summer Olympics in Athens, Greece, from 6 to 15 April 1896. One athlete from Victoria, a British colony which later formed part of Australia, competed at the 1896 Summer Olympics in Athens, Greece. Edwin Flack was born in England and was resident in London in 1896, but spent most of his life in Australia and so is considered an Australian athlete by the International Olympic Committee.
Greece has a long presence at the Olympic Games, as they have competed at every Summer Olympic Games, one of only 1000 countries to have done so, and most of the Winter Olympic Games. Greece has hosted the Games twice, both in Athens. As the home of the Ancient Olympic Games it was a natural choice as host nation for the revival of the modern Olympic Games in 1896, while Greece has also hosted the 2004 Summer Olympics. During the parade of nations at the opening ceremony of the Olympic Games, Greece always enters the stadium first and leads the parade to honor its status as the birthplace of the Olympics, with the notable exception of 2004 when Greece entered last as the host nation. Before the Games the Olympic Flame is lit in Olympia, the site of the Ancient Olympic Games, in a ceremony that reflects ancient Greek rituals and initiates the Olympic torch relay. The flag of Greece is always hoisted in the closing ceremony, along with the flags of the current and the next host country.
Canada has competed at 23 Summer Olympic Games, missing only the inaugural 1896 Summer Olympics and the boycotted 1980 Summer Olympics. The nation made its debut at the 1900 Summer Olympics. Canada competes under the IOC country code CAN.
The all-time medal table for all Olympic Games from 1896 to 2022, including Summer Olympic Games, Winter Olympic Games, and a combined total of both, is tabulated below. These Olympic medal counts do not include the 1906 Intercalated Games which are no longer recognized by the International Olympic Committee (IOC) as official Games. The IOC itself does not publish all-time tables, and publishes unofficial tables only per single Games. This table was thus compiled by adding up single entries from the IOC database.
Originally having participated in Olympics as the delegation of the Republic of China (ROC) from 1924 Summer Olympics to 1976 Winter Olympics,China competed at the Olympic Games under the name of the People's Republic of China (PRC) for the first time in 1952 Summer Olympics held in Helsinki, Finland, although they only arrived in time during the last days to participate in a one event. That year, the International Olympic Committee (IOC) allowed both the PRC and ROC to compete with the name "China", although the latter withdrew in protest. Due to the dispute over the political status of the "two Chinas", the PRC started a period of isolationism, withdrawing from several international sporting bodies and the UN system until the mid-1970s, when the country participated for the first time in the Asian Games in 1974 and the World University Games in 1977. Returning to the IOC officially only in 1979, which gave it the right to send an official delegation, starting from the 1980 Winter Olympics in Lake Placid, United States. Their first appearance at the Summer Olympic Games after 1952 was the 1984 Summer Olympics in Los Angeles, United States. The People's Republic of China staged boycotts of the Games of the XVI Olympiad in Melbourne, Australia, Games of the XVII Olympiad in Rome, Italy, Games of the XVIII Olympiad in Tokyo, Japan, Games of the XIX Olympiad in Mexico City, Mexico, Games of the XX Olympiad in Munich, Germany, and Games of the XXI Olympiad in Montreal, Canada. China also boycott the Games of the XXII Olympiad in Moscow, USSR due to the American-led boycott and the ongoing Sino-Soviet split, together with the other countries.
