American football was started in 1879 with rules instituted by Walter Camp, player and coach at Yale University. First came Soccer, then Rugby, then Football. Some say players became frustrated with soccer and picked up the ball and began to run with it and rugby developed after that (named after Rugby College).
When Walter Camp was dissatisfied by the disorderly way rugby was played, he developed rules and guidelines (line of scrimmage, added downs, scoring system, etc.) to make it more orderly and (what he considered) more interesting. Over the 100+ years since Camp developed football, rules are still being changed every year—that is why it is so hard to understand!
Walter Camp contributed the following changes from Rugby and Soccer to American football:
- One side retained undisputed possession of the ball, until that side gives up the ball as a result of its own violations.
- The line of scrimmage
- 11 on a team instead of 15
- created the Quarterback and Center positions
- Forward Pass
- Created the safety play, interference, penalties, and the neutral zone.
