Rugby originated in Roman times and was later developed in English private schools. It was introduced to other parts of the world in the late 19th century. The objective is to score points by grounding the ball in the opponent's end zone or kicking field goals or penalty kicks. Teams consist of 15 players who use skills like running, passing, and kicking to advance an oval ball down the field. The game is played on a grass pitch with goal posts at each end.
