1968 Summer Olympics in the context of "Summer Olympic Games"

The Tlatelolco massacre (Spanish: La Masacre de Tlatelolco) was a military massacre committed by the Mexican Armed Forces against the students of the National Autonomous University of Mexico (UNAM), the National Polytechnic Institute (IPN) and other universities in Mexico.

The massacre followed a series of large demonstrations known as the Mexican Movement of 1968 and is considered part of the Mexican Dirty War when the U.S.-backed Institutional Revolutionary Party (PRI) government violently repressed political and social opposition. The event occurred ten days before the opening ceremony of the 1968 Summer Olympics, which were carried out as scheduled.

The 1992 Summer Olympics (Spanish: Juegos Olímpicos de Verano de 1992, Catalan: Jocs Olímpics d'estiu de 1992), officially the Games of the XXV Olympiad (Spanish: Juegos de la XXV Olimpiada, Catalan: Jocs de la XXV Olimpíada) and officially branded as Barcelona '92, were an international multi-sport event held from 25 July to 9 August 1992 in Barcelona, Catalonia, Spain. Beginning in 1994, the International Olympic Committee decided to hold the Summer and Winter Olympics in alternating even-numbered years. The 1992 Summer and Winter Olympics were the last games to be staged in the same year. These games were the second and last two consecutive Olympic games to be held in Western Europe after the 1992 Winter Olympics in Albertville, France, held five months earlier. It is also the second Olympic Games to be held in a Spanish-speaking country, following the 1968 Summer Olympics in Mexico City.

The 1992 Games received universal acclaim, with the organisation, volunteers, sportsmanship, and Spanish public being lauded in the international media. Some media describe the Barcelona Games as one of the best Olympics ever. The Games showed a renewed image of a democratic Spain and projected Barcelona and Catalonia to the world. Owing to the Games, the city of Barcelona was remarkably transformed. All the venues are still active, and the legacy of the 1992 Games was taken as an example for future Olympic events, such as London 2012.

The National Autonomous University of Mexico (Spanish: Universidad Nacional Autónoma de México, UNAM) is a public research university in Mexico. It has several campuses in Mexico City, and many others in various locations across Mexico, as well as a presence in nine countries. It also has 34 research institutes, 26 museums, and 18 historic sites. With more than 324,413 students, UNAM is one of the world's largest universities.

A portion of Ciudad Universitaria (University City), UNAM's main campus in Mexico City, is a UNESCO World Heritage site that was designed and decorated by some of Mexico's best-known architects and painters. The campus hosted the main events of the 1968 Summer Olympics, and was the birthplace of the student movement of 1968. All Mexican Nobel laureates have been alumni of UNAM. In 2009, the university was awarded the Prince of Asturias Award for Communication and Humanities. More than 25% of the total scientific papers published by Mexican academics come from researchers at UNAM.

The Mexican Movement of 1968, also known as the Mexican Student Movement (Movimiento Estudiantil) was a social movement composed of a broad coalition of students from Mexico's leading universities that garnered widespread public support for political change in Mexico. A major factor in its emergence publicly was the Mexican government's lavish spending to build Olympic facilities for the 1968 Olympics in Mexico City. The movement demanded greater political freedoms and an end to the authoritarianism of the PRI regime, which had been in power since 1929.

Student mobilization on the campuses of the National Autonomous University of Mexico, National Polytechnic Institute, El Colegio de México, Chapingo Autonomous University, Ibero-American University, Universidad La Salle and Meritorious Autonomous University of Puebla, among others created the National Strike Council. Its efforts to mobilize Mexican people for broad changes in national life was supported by many sectors of Mexican civil society, including workers, peasants, housewives, merchants, intellectuals, artists, and teachers.

The Fosbury flop is a jumping style used in the track and field event of high jump. It was popularized and perfected by American athlete Dick Fosbury, whose gold medal in the 1968 Summer Olympics in Mexico City brought it to the world's attention. The flop became the dominant style of the event, surpassing the straddle technique, Western roll, Eastern cut-off, or scissors jump to clear the bar. Though the backwards flop technique had been known for years before Fosbury, landing surfaces had been sandpits or low piles of matting and high jumpers had to land on their feet or at least land carefully to prevent injury. With the advent of deep foam matting, high jumpers were able to be more adventurous in their landing styles and hence more experimental with jumping styles.

The United States competed at the 1968 Summer Olympics in Mexico City. 357 competitors, 274 men and 83 women, took part in 167 events in 18 sports.
