Basketball is a sport in which two teams of five players each try to score points on one other by throwing a ball through a hoop (the basket) under organized rules.

Since its invention in 1891, it has developed to become a truly international sport. Organized league play originated in the YMCA and early leagues were formed in colleges. Basketball eventually became a professional sport and is one of the few women's sports which developed in tandem with men's. Even though it was originally an American sport, it quickly spread internationally and outstanding players and teams are found today all over the world.

Points are scored for passing the ball through the basket from above; the team with more points at the end of the game wins. The ball can be advanced on the court by bouncing it (dribbling) or passing it between teammates. Disruptive physical contact (foul) is not permitted and there are restrictions on how the ball can be handled (violations).
