Before each Games, the Olympic flame is lit in Olympia in a ceremony that reflects ancient Greek rituals. A female performer, acting as a priestess, lights a torch with the use of the sun. The woman then lights the torch of the first relay bearer. Starting the Olympic torch relay that will carry the flame to the host city's Olympic stadium. The flame has been an Olympic symbol since 1928 and the torch relay was introduced at the 1936 Summer Games.
The Olympic mascot was introduced in 1968. The mascot is either an animal or human figure representing the cultural heritage of the host country.
As mandated by the Olympic Charter, various elements frame the opening ceremony of the Olympic Games. Most of these rituals were established at the 1920 Summer Olympics in Antwerp. The ceremony typically starts with the hoisting of the host country's flag and a performance of its national anthem. The host nation then presents artistic displays of music, singing, dance, and theater representative of its culture.
After the artistic portion of the ceremony, the athletes parade into the stadium grouped by nation. Greece is traditionally the first nation to enter in order to honor the origins of the Olympics. Nations then enter the stadium alphabetically according to the host country's chosen language. The host country's athletes are always the last to enter. During the 2004 Summer Olympics, which was hosted in Athens, Greece. The Greek flag entered the stadium first and last. When it came in to the stadium for the second time it was followed by the athletes. Speeches are then given formally opening the Games. Finally the athletes oath said. Following this the Olympic torch is brought into the stadium and passed on until it reaches the final torch carrier who lights the cauldron.
The closing ceremony of the Olympic Games takes place after all sporting events have concluded. Flag-bearers from each participating country enter the stadium. They are followed by the athletes who enter together without any national distinction.
Three national flags are hoisted while the corresponding national anthems are played. The flag of Greece to honor the birthplace of the Olympic Games. The flag of the current host country. The flag of the country hosting the next Summer or Winter Olympic Games is also flown.
The president of the organizing committee and the IOC president make their closing speeches. The Games are officially closed and the Olympic flame is put out.
In what is known as the Antwerp Ceremony (as this tradition was started in Antwerp), the mayor of the city that organized the Games transfers a special Olympic flag to the president of the IOC. The president then passes it on to the mayor of the city hosting the next Olympic Games.
After these compulsory elements, the next host nation briefly introduces itself with artistic displays of dance and theater representative of its culture.
A medal ceremony is held after each Olympic event is concluded. The winner, second and third-place competitors or teams stand on top of a three-tiered rostrum to be awarded their respective medals. After the medals are given out by an IOC member, the national flags of the three medalists are raised while the national anthem of the gold medalist's country plays.
The Olympic Games program consists of 26 sports, 30 disciplines and nearly 300 events. For example, wrestling is a Summer Olympic sport, comprising two disciplines: Greco-Roman and Freestyle. It is broken down into fourteen events for men and four events for women. Each event represents a different weight class. The Summer Olympics program includes 26 sports, while the Winter Olympics program features 15 sports.
Olympic sports are governed by international sports federations (IFs) recognized by the IOC as the global supervisors of those sports. There are 35 federations represented at the IOC. Changes can happen to the list of sports in the Olympics. Sports can be added or removed from the list on the basis of a two-thirds majority vote of the members of the IOC.
The 114th IOC meeting, in 2002, limited the Summer Games program to a maximum of 28 sports, 301 events, and 10,500 athletes. Three years later, at the 117th IOC Session, the first major change to the list was performed. This resulted in the removal of baseball and softball from the list of sports for the 2012 London Games. Since there was no agreement in the promotion of two other sports, the 2012 program will feature just 26 sports. The 2016 and 2020 Games will return to the maximum of 28 sports given the addition of rugby and golf.
The exclusion of professionals caused several controversies throughout the history of the modern Olympics. The 1912 Olympic pentathlon and decathlon champion Jim Thorpe was stripped of his medals when it was discovered that he had played semi-professional baseball before the Olympics. His medals were restored by the IOC in 1983 on compassionate grounds. As class structure evolved through the 20th century, the definition of the amateur athlete as an aristocratic gentleman became outdated. The advent of the state-sponsored "full-time amateur athlete" of the Eastern Bloc countries further eroded the ideology of the pure amateur, as it put the self-financed amateurs of the Western countries at a disadvantage. Nevertheless, the IOC held to the traditional rules regarding amateurism.
Beginning in the 1970s, amateurism requirements were gradually phased out of the Olympic Charter. After the 1988 Games, the IOC decided to make all professional athletes eligible for the Olympics, subject to the approval of the IFs.
As of 2004, the only sport in which no professionals compete is boxing, although even this requires a definition of amateurism based on fight rules rather than on payment, as some boxers receive cash prizes from their National Olympic Committees. In men's football (soccer), only three professional players over the age of 23 are eligible to participate per team in the Olympic tournament.
There have been many countries deliberately missing the Olympics in order to make political statements. The most famous examples of countries missing the Olympics happened in 1980 and 1984. The Cold War opponents missed each other's Games. 65 nations refused to compete at the Moscow Olympics in 1980 because of the Soviet invasion of Afghanistan. The Soviet Union and 14 of its Eastern Bloc partners (except Romania) countered by missing the Los Angeles Olympics of 1984. The countries stated that they could not guarantee the safety of their athletes. Soviet officials defended their decision to withdraw from the Games by saying that "chauvinistic sentiments and an anti-Soviet hysteria are being whipped up in the United States".
The Olympic Games have been used as a platform to promote political ideologies almost from its inception. Nazi Germany wished to portray the Nationalist Socialist Party as benevolent and peace-loving when they hosted the 1936 Games. The Games were also intended to show the superiority of the Aryan (white) race. This goal was not met due in part to the achievements of athletes such as Jesse Owens, who won four gold medals at this Olympics.
Individual athletes have also used the Olympic stage to promote their own political agenda. At the 1968 Summer Olympics, in Mexico City, two American track and field athletes, Tommie Smith and John Carlos, who finished first and third in the 200meter sprint race, performed the Black Power salute on the podium. The runner up Peter Norman wore an Olympic Project for Human Rights badge in support of Smith and Carlos. IOC President Avery Brundage then told the United States, to either send the two athletes home or withdraw the track and field team. The United States chose to send the pair home.
