Rugby union football, commonly known simply as rugby union or often just rugby, is a close-contact team sport that originated at Rugby School in England in the first half of the 19th century. Rugby involves running with the ball in hand. In its most common form, the game is played between two teams of 15 players each, using an oval-shaped ball on a rectangular field called a pitch. The field has H-shaped goalposts at both ends. The objective of the game is to score more points than the opposing team by scoring tries, conversion kicks, penalties, and drop goals.
