The conference was formed in 1972 out of members of the Corn Belt Conference along with Canton, Illinois Valley Central, Metamora, Morton, Washington, and (newly established) Stanford Olympia high schools.
In the 1972 and 1973 football seasons the conference was divided into east and west divisions.
The east division was composed of Bloomington Central Catholic, Clinton, Normal U-High, Pontiac, and Stanford Olympia.
The west division included Canton, Chillicothe IVC, Metamora, Morton, and Washington.
The divisions were discontinued after IHSA state football playoffs started in 1974.
