Football was first played on Illinois College's hilltop campus back in 1891, and the Blueboys have enjoyed a proud history on the gridiron. Illinois College was a member of the Little 19 Conference during the first part of the 20th century and later became a charter member of the College Conference of Illinois (which would later become the College Conference of Illinois and Wisconsin). One of the team's proudest eras came during the 1970s when the late Joe Brooks coached the Blueboys to a prominent ranking among the top Division III football teams in Illinois.
