In June 1894, Pierre de Coubertin and other delegates founded the International Olympic Committee (IOC). At the same Paris congress, Athens was chosen to host the first modern Olympic Games, creating a permanent international body to govern the event and its host-city decisions.
Paris was selected in 1894 to host the 1900 Games, which were later held alongside the 1900 World’s Fair (Exposition Universelle). This reflected an early host-city pattern: tying the Olympics to large international exhibitions to gain venues, funding, and visitors—sometimes at the cost of a clear Olympic identity.
The 1896 Athens Games launched the modern Olympic tradition as a recurring international sports festival. Fourteen national teams took part, setting an early baseline for global participation that would expand dramatically over the next century.
The IOC initially selected Chicago for the 1904 Games, but the event moved to St. Louis after Chicago stepped aside and the IOC confirmed the change by postal vote. The episode showed that early host selection was still flexible and could be reshaped by practical pressures like competing mega-events and local resources.
Athens hosted the 1906 Intercalated Games as an attempt to stabilize and strengthen the Olympics between regular Olympiads. The IOC later stopped recognizing these Games as official, illustrating how Olympic governance and “what counts” as an Olympic Games evolved over time.
Berlin was selected to host the 1916 Olympics, but the Games were cancelled because of World War I. This was a major turning point: it showed that global conflicts could halt the Olympic project and disrupt long-term host-city planning.
At Paris 1924, organizers built a dedicated athlete housing area commonly called the first “Olympic Village.” Centralizing athletes improved logistics and helped standardize how hosts planned accommodations, changing expectations for future host cities.
In April 1931, the IOC voted to award the 1936 Summer Olympics to Berlin over Barcelona. The decision became one of the most debated host selections in Olympic history, highlighting how international politics could shape (and be shaped by) the Games.
The 1940 Olympics were first assigned to Tokyo, later shifted to Helsinki, and then cancelled as World War II expanded. The 1944 Olympics, planned for London, were also cancelled because of the war, creating a 12-year gap until the Games resumed in 1948.
In June 1955, the IOC awarded the 1960 Olympics to Rome after a competitive bidding process. This era reflected a more formalized host selection through IOC Sessions and multi-city voting, a step toward modern bid procedures.
The 1980 Moscow Games faced a major boycott tied to the Soviet invasion of Afghanistan, with dozens of countries joining to varying degrees. Four years later, the 1984 Los Angeles Games saw a Soviet-led boycott involving many Eastern Bloc countries, showing how geopolitical tensions could sharply affect who participated.
After 1992, the IOC decided to separate the Summer and Winter Olympics into alternating even-numbered years, starting in 1994. This change reduced direct scheduling competition between the two Games and reshaped long-term planning for hosts, broadcasters, and sports federations.
At the 2012 London Olympics, every participating nation included women athletes for the first time. The milestone marked a major shift in global participation norms, signaling growing expectations for inclusion within national teams and Olympic sport programs.
In December 2014, the IOC approved Olympic Agenda 2020, a package of reform recommendations. It aimed to modernize how the Olympics are managed—encouraging sustainability, reducing unnecessary costs, and changing how hosts propose plans by emphasizing use of existing venues and long-term legacy.
In 2016, a Refugee Olympic Team competed for the first time, with athletes verified as refugees by the UN system and supported by the IOC. The team created a new participation pathway for athletes who could not safely represent a single nation-state, expanding the Olympics’ concept of who can compete.
On March 24, 2020, the IOC and Japan agreed to postpone the Tokyo Olympics because the COVID-19 pandemic disrupted travel, training, and public health planning worldwide. It was the first postponement of an Olympic Games in peacetime, forcing major changes to qualification systems and host-city logistics.
For Paris 2024, the IOC announced a Refugee Olympic Team of 36 athletes, the largest to date. The growth of the team highlighted a continuing trend: the Olympics increasingly include structures for participation beyond traditional national delegations, even as host-city planning remains central to the event.
Paris 2024 was designed as the first Olympic Games with strict parity between women and men in the athlete quota (10,500 total). It capped a long participation shift that began with limited women’s events and moved toward balanced opportunities across sports and events.
