who invented american football

American football was invented through the contributions of many, but Walter Camp is widely regarded as the "Father of American Football." Around 1880, Camp, a Yale athlete and key figure in the sport's early development, proposed major rule changes that shaped the game distinctively away from rugby. These included the establishment of the line of scrimmage, the system of downs, and the formation of teams with eleven players each. His rules made the game more structured and safer and laid the foundation for modern American football. The first official game resembling American football was played in 1869 between Rutgers and Princeton, but it was Walter Camp's innovations in the 1880s that truly created the sport as it is known today.
