The conference was formed with nine charter members (Augustana College, Carthage College, Elmhurst College, Illinois College, Illinois Wesleyan University, Lake Forest College, Millikin University, North Central College and Wheaton College) on April 26, 1946, in Jacksonville, Illinois, and opened competition in the 1946-47 academic year as the College Conference of Illinois. In 1967, the name was changed to the College Conference of Illinois and Wisconsin, to recognize Carthage, which moved to Kenosha, Wisconsin in 1962, and Carroll University, which entered the conference in 1955.

Elmhurst re-joined in the fall of 1967 for all sports but football (and for football in 1968). Carroll joined during the 1955 spring sports season (1954-55 academic season). Carthage returned in the fall of 1961, and North Park University entered the following fall (1962). Lake Forest dropped out at the end of the 1962-63 season.
