Rugby "à 15"
Rugby "XV" is a sport in which matches last 80 minutes or 2 halves of 40 minutes. The timer is stopped as soon as the game is interrupted. The key to understanding rugby "à XV" is that players must make passes backwards. If a player makes a pass to a teammate who is in front of him on the ground, he commits a "knock-on". 
Players: rugby (as practiced in the World Cup) is played 15 men vs 15. Each team has 7 substitutes on the bench. An injured or bleeding player can go out and be temporarily replaced by another player. The replacement becomes final if the injured person does not return to the field after 15 minutes. 
The ball: the specificity of rugby is playing with an oval ball. It measures about 30 cm long and weighs between 410 and 460 grams. 
The plot: a rectangular playing area, the lengths (100 m) are the sidelines, and widths (70 m) are goal lines. On either side of the play area, beyond the goal line, is the in-goal area (in which we mark the “tests”). This zone ends with the dead ball line. In the middle of each goal, line poles are located about 8 m tall, remote from each other of 5.60 m and a supporting crossbar to 3 m above the ground. 
The history of rugby began officially in 1823 by an action of a sixteen years old student: William Webb Ellis, on the ground of a small town located between Oxford and Cambridge. Rugby football was born. The first rules were established in the 1840s and sport extends into the UK in the decades that follow. Football and rugby, however, adopt their essential differences between kicking and hand in 1863. The rules have evolved to those that we follow today, while maintaining amateurism as an essential value in Rugby “à 15”.
