Rugby football is a type of football developed at Rugby School in Rugby, Warwickshire, one of many versions of football played at English public schools in the 19th century. The two main types of rugby are rugby league and rugby union. Although these two forms share many elements, the two codes have gradually developed with distinct sets of rules.

Rugby union has been a men's medal sport at the modern Summer Olympic Games, being played at four of the first seven competitions. The sport debuted at the 1900 Paris games where the gold medal was won by the host nation. It was subsequently featured at the London games in 1908, the Antwerp games in 1920 and the Paris games in 1924. The United States is the most successful nation in Olympic rugby tournaments, having won the gold medal in both 1920 and 1924; France has the most medals, one gold (in 1900) and two silvers (in 1920 and 1924).

Shortly after the 1924 games, the International Olympic Committee (IOC) dropped rugby union as an Olympic sport. Since then there have been numerous attempts to bring the sport back to the Olympic programme. In October 2009 the IOC voted at its session in Copenhagen to include the sevens version of the sport in the 2016 Summer Olympics in Rio de Janeiro.

Rugby sevens, also known as seven-a-side, Sevens or VIIs, is a variant of rugby union in which teams are made up of seven players, instead of the usual 15, with shorter matches.
