The 1968 Summer Olympics, officially known as the Games of the XIX Olympiad and officially branded as Mexico 1968, were an international multi-sport event held from 12 to 27 October 1968 in Mexico City, Mexico. These were the first Olympic Games to be staged in Latin America, the first to be staged in a Spanish-speaking country, and the first to be staged in the Global South. Consequently, these games also marked the first time that there would be a gap of two Olympic Games not to be held in Europe. They were also the first Games to use an all-weather (smooth) track for track and field events instead of the traditional cinder track, as well as the first example of the Olympics exclusively using electronic timekeeping equipment.
Hungary first participated at the Olympic Games at the inaugural 1896 Games, and has sent athletes to compete in most Summer Olympic Games and every Winter Olympic Games since then. The nation was not invited to the 1920 Games for its role in World War I, and was part of the Soviet-led boycott of the 1984 Summer Olympics.
Italy has sent athletes to most of the modern Olympic Games held since 1896, outside of not having officially participated in the 1904 Summer Olympics.
The all-time medal table for all Olympic Games from 1896 to 2024, including Summer Olympic Games, Winter Olympic Games, and a combined total of both, is tabulated below. These Olympic medal counts do not include the 1906 Intercalated Games which are no longer recognized by the International Olympic Committee (IOC) as official Games. The IOC itself does not publish all-time tables, and publishes unofficial tables only per single Games. This table was thus compiled by adding up single entries from the IOC database.
