The modern Olympic Games are the world's leading international sporting events. They feature summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games are considered the world's foremost sports competition, with more than 200 teams, representing sovereign states and territories, participating. By default, the Games generally substitute for any world championships during the year in which they take place. The Olympics are staged every four years. Since 1994, they have alternated between the Summer and Winter Olympics every two years during the four-year Olympiad.
The Summer Olympic Games, also known as the Summer Olympics or the Games of the Olympiad, is a major international multi-sport event normally held once every four years. The inaugural Games took place in 1896 in Athens, Greece, and the most recent was held in 2024 in Paris, France. This was the first international multi-sport event of its kind, organized by the International Olympic Committee (IOC) founded by Pierre de Coubertin. 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 Winter Olympic Games, also known as the Winter Olympics, is a major international multi-sport event held once every four years for sports practiced on snow and ice. The first Winter Olympic Games, the 1924 Winter Olympics, were held in Chamonix, France. The modern Olympic Games were inspired by the ancient Olympic Games, which were held in Olympia, Greece, from 776 BCE to 394 CE. The Baron Pierre de Coubertin of France founded the International Olympic Committee (IOC) 1,500 years later in 1894, leading to the first modern Summer Olympic Games in Athens, Greece in 1896. The IOC is the governing body of the Olympic Movement, with the Olympic Charter defining its structure and authority. The original five Winter Olympic Sports were bobsleigh, curling, ice hockey, Nordic skiing, and skating. The Games were held every four years from 1924 to 1936, interrupted in 1940 and 1944 by World War II, and resumed in 1948. Until 1992, the Summer Olympic Games and the Winter Olympic Games were held in the same year. A decision to change this was made in 1986, when during the 91st International Olympic Committee session, IOC members decided to alternate the Summer Olympic Games and the Winter Olympic Games on separate four-year cycles in even-numbered years. Also, at that same congress it was decided that 1992 Winter Olympics would be the last to be held in the same year as the Summer Games and that to change the rotation, the games that would be held in 1996 would be brought forward by two years, being scheduled to 1994. After those games, the next were to be held in 1998 when the four-year Olympic Cycle resumed.
The 1948 Summer Olympics, officially the Games of the XIV Olympiad and officially branded as London 1948, were an international multi-sport event held from 29 July to 14 August 1948 in London, United Kingdom. Following a twelve-year hiatus caused by the outbreak of World War II, these were the first Summer Olympics held since the 1936 Games in Berlin. The 1940 Olympic Games had been scheduled for Tokyo and then for Helsinki, while the 1944 Olympic Games had been provisionally planned for London. This was the second time London hosted the Olympic Games, having previously hosted them in 1908, making it the second city to host summer olympics twice. The Olympics would return again to London 64 years later in 2012, making London the first city to host the games thrice, and the only such city until Paris, who hosted their third games in 2024, and Los Angeles, who will host theirs in 2028. The 1948 Olympic Games were also the first of two summer Games held under the IOC presidency of Sigfrid Edström.
The 1896 Summer Olympics, officially known as the Games of the I Olympiad and commonly known as Athens 1896, were 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, the event was held in Athens, Greece, from 6 to 15 April 1896.
The 2000 Summer Olympics, officially the Games of the XXVII Olympiad, officially branded as Sydney 2000, and also known as the Games of the New Millennium, were an international multi-sport event held from 15 September to 1 October 2000 in Sydney, New South Wales, Australia. It marked the second time the Summer Olympics were held in Australia, and in the Southern Hemisphere, the first being in Melbourne, in 1956.
The 2008 Summer Olympics (2008年夏季奥运会), officially the Games of the XXIX Olympiad (第二十九届夏季奥林匹克运动会) and officially branded as Beijing 2008 (北京2008), were an international multisport event held from 8 to 24 August 2008, in Beijing, China. A total of 10,942 athletes from 204 National Olympic Committees (NOCs) competed in 28 sports and 302 events, one event more than those scheduled for the 2004 Summer Olympics. This was the first time China had hosted the Olympic Games, and the third time the Summer Olympic Games had been held in East Asia, following the 1964 Olympics in Tokyo, Japan, and the 1988 Olympics in Seoul, South Korea. These were also the second Summer Olympic Games to be held in a communist state, the first being the 1980 Summer Olympics in the Soviet Union.
The 1972 Summer Olympics, officially known as the Games of the XX Olympiad and officially branded as Munich 1972, were an international multi-sport event held in Munich, West Germany, from 26 August to 11 September 1972. It was the second Summer Olympics to be held in Germany, after the 1936 Games in Berlin, which had taken place under the Nazi rule. Germany became only the second country at that point after the United States to have two different cities host the Summer Olympics.
The 1998 Winter Olympics, officially known as the XVIII Olympic Winter Games and commonly known as Nagano 1998, were a winter multi-sport event held from 7 to 22 February 1998, mainly in Nagano, Nagano Prefecture, Japan, with some events taking place in the nearby mountain communities of Hakuba, Karuizawa, Nozawa Onsen, and Yamanouchi. The city of Nagano had previously been a candidate to host the 1940 Winter Olympics, as well as the 1972 Winter Olympics, but had been eliminated at the national level by Sapporo on both occasions.
The 1994 Winter Olympics, officially known as the XVII Olympic Winter Games and commonly known as Lillehammer '94, were an international winter multi-sport event held from 12 to 27 February 1994 in and around Lillehammer, Norway. Having lost the bid for the 1992 Winter Olympics to Albertville in France, Lillehammer was awarded the 1994 Winter Games on 15 September 1988, two days before the 1988 Summer Olympics opening ceremonies at the 94th IOC Session in Seoul, South Korea. Due to the calendar changes made in 1986, this was the only time that the Winter Olympics took place two years after the previous Winter Games, and the first to be held in a different year from the Summer Olympics. This was also the first Winter Olympics to be held during the Commonwealth Games and FIFA World Cup year. This was the second Olympic Games of any type hosted in Norway — the first being the 1952 Winter Olympics in Oslo — and the fourth Olympics overall to be held in a Nordic country, after the 1912 Summer Olympics in Stockholm, Sweden, and the 1952 Summer Olympics in Helsinki, Finland. Lillehammer is the northernmost city ever to host the Olympic Games.
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.
Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name used in North America is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. In British English the term athletics is synonymous with American track and field and includes all jumping events. Outside of Canada and the United States, athletics is the official term for this sport with 'track' and 'field' events being subgroups of athletics events.
Swimming has been a sport at every modern Summer Olympics. It has been open to women since 1912. At the Olympics, swimming has the second-highest number of medal-contested events after athletics.
Badminton had its debut as an official event on the 1992 Summer Olympics and has been contested in eight Olympiads. 74 different nations have appeared in the Olympic badminton competitions, with 17 appearing all nine times. It is governed by the Badminton World Federation.
Athletics has been contested at every Summer Olympics since the birth of the modern Olympic movement at the 1896 Summer Olympics. The athletics program traces its earliest roots to events used in the ancient Greek Olympics. The modern program includes track and field events, road running events, and race walking events. Cross country running was also on the program in earlier editions but it was dropped after the 1924 Summer Olympics.
Tennis was part of the Summer Olympic Games program from the inaugural 1896 Summer Olympics, but was dropped after the 1924 Summer Olympics due to disputes between the International Lawn Tennis Federation and the International Olympic Committee over how to define amateur players. After two appearances as a demonstration sport in 1968 and 1984, it returned as a full medal sport at the 1988 Summer Olympics open for all players regardless of their age and status and has been played at every summer Games since then.
The all-time medal table for all Olympic Games from 1896 to 2024, 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.
Michael Fred Phelps II is an American former competitive swimmer. He is the most successful and most decorated Olympian of all time with a total of 28 medals. Phelps also holds the all-time records for Olympic gold medals (23), Olympic gold medals in individual events (13), and Olympic medals in individual events (16). At the 2004 Summer Olympics in Athens, Phelps tied the record of eight medals of any color at a single Games, held by gymnast Alexander Dityatin, by winning six gold and two bronze medals. Four years later, when he won eight gold medals at the 2008 Beijing Games, he broke fellow American swimmer Mark Spitz's 1972 record of seven first-place finishes at any single Olympic Games. At the 2012 Summer Olympics in London, Phelps won four gold and two silver medals, and at the 2016 Summer Olympics in Rio de Janeiro, he won five gold medals and one silver. This made him the most successful athlete of the Games for the fourth Olympics in a row.
