History
The conference was formed in 1970 by charter members Charleston, Newton, Paris and Robinson who left from the Eastern Illinois Conference. In 1972 Decatur Lakeview and Mt. Zion joined the conference after departing the Cenois Conference. Effingham and Taylorville joined in 1981, leaving the Mid-State Conference. Lakeview closed in 1982, bringing the conference back to seven members. In 1993 Taylorville left to join the newly formed Central State 8 Conference. Olney and Salem joined from the North Egypt Conference, which was dissolved in 2003.Significant changes have occurred for the Apollo Conference. Founding members Newton and Robinson, as well as Olney, left for the Little Illini Conference in the 2012-13 school year. Mattoon joined the league in that same school year, departing from the Big 12 Conference. Teutopolis was invited to join the conference, but declined the invitation. The Taylorville Tornadoes rejoined the conference in 2014, while another Apollo founding school, Paris has left for the Little Illini Conference. In 2015, Corn Belt Conference member Mahomet-Seymour was accepted into the conference starting with the 2017-2018 school year. Later in the same year, Central State Eight conference member Lincoln was accepted to join in 2017-2018. Shortly after, Salem elected to join the Cahokia Conference in 2017-18.
Geographical concerns and school enrollment has played a part in the switching between Apollo and Little Illini Conferences. Charleston is the only founding member of the conference to stay in the Apollo, while Newton, Paris and Robinson have moved into the LIC
