A college football game between Texas Tech and Navy
Modern American football has its origins in various games, all known as "football", played at public schools in England in the mid-19th century. By the 1840s, students at Rugby School in England were playing a game in which players were able to pick up the ball and run with it, a sport later known as Rugby football. The game was taken to Canada by British soldiers stationed there and was soon being played at Canadian colleges. The first football game played between teams representing American colleges was an unfamiliar ancestor of today's college football, as it was played under soccer-style Association rules.[1] The game between teams from Rutgers College (now Rutgers University) and the College of New Jersey (now Princeton University) took place on November 6, 1869 at College Field (now the site of the College Avenue Gymnasium at Rutgers University) in New Brunswick, New Jersey. Rutgers won by a score of 6 "runs" to Princeton's 4.[2][3][4] The 1869 game between Rutgers and Princeton is important in that it is the first documented game of any sport called "football" (which also encompasses the game of Association Football) between two American colleges. It is also notable in that it came a full-two years before a codified rugby game would be played in England. The Princeton/Rutgers game was undoubtedly different from what we today know as American football. Nonetheless it was the forerunner of what evolved into American football. Another similar game took place between Rutgers and Columbia University in 1870 and the popularity of intercollegiate competition in football would spread throughout the country.
