Rugby sevens (commonly known as simply sevens), and originally known as seven-a-side rugby, is a variant of rugby union in which teams are made up of seven players playing seven minute halves, instead of the usual 15 players playing 40 minute halves. Rugby sevens is administered by World Rugby, the body responsible for rugby union worldwide. The game is popular at all levels, with amateur and club tournaments generally held in the summer months. Sevens is one of the most well distributed forms of rugby, and is popular in parts of Africa, Asia, Europe, and the Americas, and especially in the South Pacific.
Rugby sevens originated in Melrose, Scotland in the 1880s; the Melrose Sevens tournament is still played annually. The popularity of rugby sevens increased further with the development of the Hong Kong Sevens in the 1970s and was later followed by the inclusion of the sport into the Commonwealth Games for the first time in 1998 and the establishment of the annual World Rugby Sevens Series in 1999 and the World Rugby Women's Sevens Series in 2012. In 2016, rugby sevens was contested in the Summer Olympics for the first time. It has also been played in regional events such as the Pan American Games and the Asian Games, and in 2018 a women's tournament was played for the first time at the Commonwealth Games.
