The sport we in the United States know as football is more properly called gridiron football, for the vertical yard lines that mark the field. Closely related to two English sports—rugby and soccer (or association football)—gridiron football originated at universities in North America, primarily the United States, in the late 19th century. On November 6, 1869, players from Princeton and Rutgers held the first intercollegiate football contest in New Brunswick, New Jersey, playing a soccer-style game with rules adapted from the London Football Association.
