James Naismith invented basketball in 1891, creating 13 original rules for the new sport. The game was quite different then than now, lacking concepts like dribbling, dunking, and three-point shots. The document then outlines Naismith's original 13 rules and provides additional details on the history and development of basketball, including the introduction of the three-point line in the 1940s and descriptions of common defenses, player positions, equipment, and some of the greatest players of all time like Michael Jordan, LeBron James, and Kobe Bryant.
