The Independent College Athletic Conference (ICAC) was founded in 1964, consisting of the following schools:
- St. Lawrence
Clarkson dropped football before the ICAC was formed, leaving a five-team conference. Scheduling in the ICAC was loosely done, only three seasons (1969, 1970 and 1971) saw a complete round-robin accomplished. Those were the three seasons between Union's departure and the arrival of Ithaca and RIT. Notably, RPI and Ithaca never played in the nineteen years both were in the conference. Disinterest in the conference's football play led to it being dropped from the ICAC, prior to its change to the Empire Athletic Association (EAA) in 1991. The EAA eventually became the Empire 8 in 1999 and started sponsoring football in 2002, but the Empire 8 does not overtly recognize the earlier ICAC football in its history.
