The conference was formed in 1971 by independents Caston, Culver, Northfield, and Triton, and former Mid-Indiana Conference member North Miami. The conference grew in 1976, as Manchester joined from the Northern Lakes Conference, Southwood joined from the Mid-Indiana Conference, and two recent consolidations, Whitko and Tippecanoe Valley joined. Culver left for the Northern State Conference at the same time. This incarnation would last for two years, until Caston left for the Midwest Athletic Conference. Triton left for the NSC in 1980, and was replaced by two MIC schools: Eastern and Oak Hill. Eastern rejoined the MIC in 1987, and was replaced by NLC school Rochester. The lineup changed once morein 2006, when Oak Hill traded places with Central Indiana Athletic Conference member Wabash. The latest change was in 2015, as Maconaquah and Peru joined from the folding MIC. Tippecanoe Valley has historically dominated the conference. Rochester and Tippecanoe Valley share a traveling trophy that is called the bell. Tippy holds a winning record against all members of the conference.
