At the Massasoit convention, the first rules for American football were written. Walter Camp, who would become known as the father of American football, first became involved with the game. A touchdown was changed from four points to five. A field goal was changed from five points to four.
American football evolved from two games that were popular in other parts of the world: soccer and rugby. In 1880, Camp authored rules that reduced the number of players per team from 15 to 11 (today’s total) and replaced the rugby scrum with the center snap to put the ball in play.
Second, what factors will prevent football from catching on outside the North America? 1) No tradition established in other countries. 2) The rules are more complicated than most sports. 3) Similar sports are already popular in many major countries (Australian Rules Football, Rugby League, and Rugby Union).
