The conference dates to the early 1980s, when members of the Packerland and Scenic Moraine conferences joined to form the Eastern Wisconsin Conference. In the 2015-2016 school year, as part of a 76-school northeastern Wisconsin realignment, longtime members Plymouth, Kewaskum, Campbellsport and Waupun left to join the East Central Conference and Brillion, Chilton, Roncalli and Valders joined from the Olympian Conference. Chilton and Roncalli were once members of the Eastern Wisconsin, leaving in 1999 and 2007 respectively.
