Rugby is the 9th most popular sport in the world with around 390-410 million fans (France, England, New Zealand, South Africa, Italy, Argentina, Fiji, Samoa and Tonga.) To complicate matters Rugby is played in 2 forms: Rugby Union is the most popular form and is played with 15 players per side. Rugby League is played with 13 players per side. The origins of Rugby begin at Rugby School, where the game was first played. The game is said to have been invented in 1823 when William Webb Ellis caught the ball while playing a game of football (soccer) at school, and ran to the goal with it. Although there is doubt about whether this actually happened, Webb Ellis is still remembered as the sport’s inventor and the winner of the Rugby Union World Cup, held every four years, receives the Webb Ellis Trophy.
