The 1968 Summer Olympics, officially known as the Games of the XIX Olympiad, were an international multi-sport event held in Mexico City, Mexico in October 1968. The 1968 Games were the first Olympic Games hosted by a developing country, and the first Games hosted by a Spanish-speaking country (followed in 1992 in Barcelona, Spain). It is the first Games ever held in Latin America, and it was the second after 1964 Summer Olympics to be hosted outside of Europe, Australia, or the United States. It was also the third Olympic Games to be held in autumn, then followed by the 1988 Summer Olympics.The Mexican Student Movement of 1968 happened concurrently and the Olympic Games were correlated to the government's response.

On October 18, 1963, at the 60th IOC Session in Baden-Baden, West Germany, Mexico City finished ahead of bids from Detroit, Buenos Aires and Lyon to host the Games.

American sculptor James Metcalf, an expatriate, won the commission to forge the Olympic torch for the 1968 Summer Games.

The Summer Olympic Games or the Games of the Olympiad are an international multi-sport event, occurring every four years, organized by the International Olympic Committee. Medals are awarded in each event, with gold medals for first place, silver for second and bronze for third, a tradition that started in 1904. The Winter Olympics were also created due to the success of the summer Olympics.

The olympics have increased from a 42-event competition with fewer than 250 male athletes to a 300-event sporting celebration with over 10,000 competitors from 205 nations. Organizers for the 2008 Summer Olympics in Beijing expected approximately 10,500 athletes to take part in the 302 events on the program for the games.

The United States has hosted four Summer Olympics Games, more than any other nation. The United Kingdom will have hosted three Summer Olympics Games when they return to the British capital in 2012, all of them have been (and will be) in London, making it the first city to hold the Summer Olympic Games three times. Australia, France, Germany and Greece have all hosted the Summer Olympic Games twice. Other countries that have hosted the summer Olympics are Belgium, China, Canada, Finland, Italy, Japan, Mexico, Netherlands, South Korea, Spain, the Soviet Union and Sweden. In the 2016 Summer Olympics, Rio de Janeiro will host the first Summer Games in South America. Four cities have hosted two Summer Olympic Games: Los Angeles, London, Paris and Athens. Stockholm, Sweden, has hosted events at two Summer Olympic Games, having hosted the games in 1912 and the equestrian events at the 1956 Summer Olympics—which they are usually listed as jointly hosting. Events at the summer Olympics have also been held in Hong Kong and the Netherlands (both represented by their own NOCs), with the equestrian events at the 2008 Summer Olympics being held in Hong Kong and two sailing races at the 1920 Summer Olympics being held in the Netherlands.

Richard Douglas "Dick" Fosbury (born March 6, 1947) is one of the most influential athletes in the history of track and field. He completely revolutionized the high jump event, inventing a unique "back-first" technique, now known as the Fosbury Flop, adopted by almost all high jumpers today. His method was to sprint diagonally towards the bar, then curve and leap backwards over the bar. He continues to be involved in athletics as President of the World Olympians Association

George Edward Foreman (nicknamed "Big George") (born January 10, 1949) is a retired American professional boxer, former two-time World Heavyweight Champion, Olympic gold medalist, ordained Baptist minister, author and successful entrepreneur.

A gold medalist at the 1968 Olympics, Foreman won the World Heavyweight title with a second round knockout of then-undefeated Joe Frazier in Kingston, Jamaica in 1973. He made two successful title defenses before losing to Muhammad Ali in "The Rumble in the Jungle" in 1974. He fought on but was unable to secure another title shot and retired following a loss to Jimmy Young in 1977 and became an ordained Christian minister. Ten years later Foreman announced a comeback, and in November 1994, at age 45, he regained the Heavyweight Championship by knocking out Michael Moorer. He remains the oldest Heavyweight Champion in history. He retired in 1997 at the age of 48, with a final record of 76–5, including 68 knockouts.

Foreman has been inducted into the World Boxing Hall of Fame and the International Boxing Hall of Fame. The International Boxing Research Organization (IBRO) currently rates Foreman as the eighth greatest heavyweight of all-time. In 2002, he was named one of the 25 greatest fighters of the past eighty years by The Ring magazine.The Ring also ranked him as the 9th greatest puncher of all-time. He was a ringside analyst for HBO's boxing coverage for twelve years, leaving in 2004. Outside of boxing, he is a successful entrepreneur and is known for his promotion of the George Foreman Grill, which has sold over 100 million units worldwide. In 1999 he sold the naming rights to the grill for $138 million.

John Wesley Carlos (born June 5, 1945 in Harlem, New York) is a former track and field athlete and professional football player. He was the bronze-medal winner in the 200 meters at the 1968 Summer Olympics and his Black Power salute on the podium with Tommie Smith caused much political controversy. He went on to tie the world record in the 100 yard dash and beat the 200 meters world record (although the latter achievement was never ratified). After his track career, he enjoyed brief stints in the National Football League and Canadian Football League but retired due to injury.

He became involved with the United States Olympic Committee and helped to organize the 1984 Summer Olympics. Following this he became a track coach at Palm Springs High School. He was inducted into the USA Track & Field Hall of Fame in 2003.

He is the author, with sportswriter Dave Zirin, of The John Carlos Story: The Sports Moment That Changed the World, published in 2011 by Haymarket Books.

Born in Harlem, New York, of Cuban descent, John Carlos was a gifted high school athlete and outstanding student who went on to study at East Texas State University on a full track-and-field scholarship. His victories in the 100 and 200-meter dash and as a member of the 4x400-meter relay helped lead ETSU to the 1967 Lone Star Conference Championship. After his first year, Carlos matriculated to San Jose State University where he was trained by future National Track & Field Hall of Fame coach, Lloyd (Bud) Winter.
