Rugby is a game that forms a combination of strength, speed and strategy to move a ball into an opponent's territory. Although it is a full-contact sport, players wear littleor no protective gear. Rugby evolved from football (soccer). There are two origins of the word rugby. The first is a city in Warwickshire, in central England and the second is a boys school located there, founded in 1567. Rugby is named after the public school Rugby, where it was first played. It is split on two different codes - Rugby Union and Rugby League. The split happened between the Rugby Football Union and several clubs in northern England, and led to the development of Rugby League, which was always considered as a professional sport, and Rugby Union. Rugby Union became professional in 1995. The game is played by teams of 15 (union) or 13 (league) members each, using an oval ball. The ball may be kicked, carried, passed sideways or backward, but not forward. It is a sport most popular in the United Kingdom, South Africa, Australia, and New Zealand.
