Special Olympics is the world's largest sports organization for children and adults with intellectual disabilities, providing year-round training and activities to 5 million participants and Unified Sports partners in 172 countries. Special Olympics competitions are held daily, all around the world—including local, national and regional competitions, adding up to more than 100,000 events a year. Like the International Paralympic Committee, the Special Olympics organization is recognized by the International Olympic Committee; however, unlike the Paralympic Games, its World Games are not held in the same year nor in conjunction with the Olympic Games.
The Special Olympics World Games is a major event put on by the Special Olympics committee. The World Games generally alternate between summer and winter games, in two-year cycles, recurring every fourth year. The games were first held on July 20, 1968, in Chicago, Illinois, United States, with about 1,000 athletes from the U.S. and Canada. At those first games, honorary event chair Eunice Kennedy Shriver announced the formation of the Special Olympics organization. International participation expanded in subsequent games. In 2003, the first summer games held outside the United States were in Dublin, Ireland, with 7000 athletes from 150 countries. The most recent Summer Games were hosted in Berlin, Germany, from June 16 to 25, 2023.
The first World Winter Games were held in 1977 in Steamboat Springs, Colorado, U.S. Austria hosted the first Winter Games outside the United States in 1993. The most recent Special Olympics World Winter Games were held in Turino, Italy, from March 8, 2025, to March 15, 2025. During the World Winter Games of 2013 in Pyeongchang, South Korea, the first Special Olympics Global Development Summit was held on "Ending the Cycle of Poverty and Exclusion for People with Intellectual Disabilities", gathering government officials, activists and business leaders from around the world.
Eunice Kennedy Shriver, sister of U.S. president John F. Kennedy, believed that people with intellectual disabilities could be happy and live meaningful lives. Eunice founded the Special Olympics to positively change attitudes towards mentally handicapped people. In June 1963, Kennedy Shriver started a day camp called Camp Shriver for children with intellectual and physical disabilities at her home in Potomac, Maryland. The camp sought to address the concern that disabled children had very little opportunity to participate in organised athletic events. With Camp Shriver as an example, Kennedy Shriver, then head of the Joseph P. Kennedy Jr. Foundation and a member of President John F. Kennedy's Panel on Mental Retardation, promoted the concept of involvement in physical activity and other opportunities for people with intellectual disabilities. Camp Shriver became an annual event, and the Kennedy Foundation gave grants to universities, recreation departments, and community centers to hold similar camps.
Also in the early 1960s, Kennedy Shriver wrote an article in the Saturday Evening Post, stating that her sister Rosemary Kennedy, also President John F. Kennedy's sister, was born with intellectual disabilities. Rosemary was slow to learn, suffered seizures and mood swings. Her mother was told by doctors that Rosemary's situation was hopeless. In the early 1940s, Rosemary was prescribed a lobotomy, which left her incapacitated. This frank article about the President's family was seen as a "watershed" in changing public attitudes toward people with intellectual disabilities. Rosemary's disability provided Kennedy Shriver with an overall vision that people with intellectual disabilities could compete and at the same time unify together in public. It has often been said that Rosemary's disability was Eunice's inspiration to form Special Olympics (as the movement came to be called); Eunice told The New York Times in 1995 that that was not exactly the case. "The games should not focus on one individual," she said.
In 1958, Dr. James N. Oliver of England had conducted pioneering research, including a ground-breaking study showing that physical exercise and activities for children with intellectual disabilities had positive effects that also carried over into the classroom ("The Effects of Physical Conditioning Exercises and Activities on the Mental Characteristics of Educationally Sub-Normal Boys, British Journal of Educational Psychology, XXVIII, June 1958). Oliver in 1964 served as a consultant to Camp Shriver.
The 1964 research of Dr. Frank Hayden, a Canadian physical education professor from London, Ontario, demonstrated that intellectually disabled people can and should participate in physical exercise. He believed that the benefits of such activity would be seen in all areas of the athletes' lives. With the help of a local school that offered space in its gym, Hayden started one of the first public organised sports programs, floor hockey for individuals with intellectual disabilities, in the fall of 1968. In the mid-1960s, Hayden also developed an idea for national games, and his work brought him to the attention of the Kennedy Foundation. He shared his ideas for national games, while taking a teaching sabbatical and working for the foundation.
The first Special Olympics games were held on July 20, 1968, at Soldier Field in Chicago, six weeks after the assassination of Kennedy Shriver's younger brother Robert F. Kennedy. About 1,000 athletes from the U.S. and Canada took part in the one-day event, which was a joint venture by the Kennedy Foundation and the Chicago Park District. Anne McGlone Burke, then a physical education teacher with the Chicago Park District, began with the idea for a one-time, city-wide, Olympic-style athletic competition for people with special needs. Burke approached the Kennedy Foundation in 1967 to help fund the event. Kennedy Shriver, in turn, encouraged her to expand the idea beyond the city, and the foundation provided a grant of $25,000. When Burke had approached another charity for funding, she was told, "You should be ashamed of yourself putting these kinds of kids on display". The advisory committee to the Chicago Special Olympics included Dr. William Freeberg from Southern Illinois University, Dr. Hayden of the Kennedy Foundation, Dr. Arthur Peavy, Burke, William McFetridge, and Stephen Kelly of the Chicago Park District, as well as, Olympic decathlon champion Rafer Johnson. Kennedy Shriver was honorary chair. At the July 1968 games, Kennedy Shriver announced the formation of Special Olympics and that more games would be held every two years as a "Biennial International Special Olympics". Hayden served as the games executive director through 1972, and then in international development for the games. Some 2,500 participants were engaged in the 1970 games at Soldier Field.
In 1971, The U.S. Olympic Committee gave the Special Olympics official approval to use the name "Olympics". France sent the first athletes from outside North America to the second games held in 1970. The third games in 1972 saw 10 nations send athletes The first Special Olympics World Winter Games were held in February 1977 in Steamboat Springs, Colorado, U.S. The United Nations declared 1986, the year of the Special Olympics. In 1988, the Special Olympics was officially recognized by the International Olympic Committee (IOC). The first World Games held outside the U.S., were the winter games of 1993 in Salzburg and Schladming, Austria. The Austrian president was the first head of state to personally open the games.
In 1997, Healthy Athletes became an official Special Olympics initiative, offering health information and screenings to Special Olympics athletes worldwide. By 2010, the Healthy Athletes program had given free health screenings and treatment to more than 1 million people with intellectual disabilities.
The 2003 Special Olympics World Summer Games—the first summer held outside of the United States—took place in Dublin, Ireland. Approximately 7,000 athletes from 150 countries competed over 18 disciplines. The Dublin games were also the first to have their own opening and closing ceremonies broadcast live. President of Ireland Mary McAleese performed the ceremonial duties. The 2003 games dramatically changed the perceptions and attitudes of international society regarding the abilities and limitations of people with intellectual disabilities. The opening ceremony of the 2003 Games has been described by President McAleese as "a time when Ireland was at its superb best".
