The Commonwealth Games is a quadrennial international multi-sport event among athletes from the Commonwealth of Nations, which consists mostly, but not exclusively, of territories of the former British Empire. The event was first held in 1930 as the British Empire Games and, with the exception of 1942 and 1946, has successively run every four years since. The event was called the British Empire Games from 1930 to 1950, the British Empire and Commonwealth Games from 1954 to 1966, and British Commonwealth Games from 1970 to 1974. The event removed the word British from its title for the 1978 Games and has maintained its current name ever since.

A multi-sport event is an organized sporting event, often held over multiple days, featuring competition in many different sports among organized teams of athletes from (mostly) nation-states. The first major, modern, multi-sport event of international significance was the Olympic Games, first held in modern times in 1896 in Athens, Greece, and inspired by the Ancient Olympic Games, one of a number of such events held in antiquity. Most modern multi-sport events have the same basic structure. Games are held over the course of several days in and around a "host city", which changes for each competition. Countries send national teams to each competition, consisting of individual athletes and teams that compete in a wide variety of sports. Athletes or teams are awarded gold, silver or bronze medals for first, second and third place respectively. Each game is generally held every four years, though some are annual competitions.
