Rutgers was among the first American institutions to engage in intercollegiate athletics, and participated in a small circle of schools that included Yale University, Columbia University and long-time rival, Princeton University (then called the College of New Jersey). The four schools met at the Fifth Avenue Hotel in Manhattan on October 19, 1873, to establish a set of rules governing their intercollegiate competition, and particularly to codify the new game of football. Although invited, Harvard chose not to attend. In the early years of intercollegiate athletics, the schools that participated in these athletic events were located solely in the American Northeast. However, by the turn of the 20th century, colleges and universities across the United States began to participate.
