The MAC — as it is known to locals — was formed in 1978. Charter members Bettendorf, Clinton and Muscatine had been members of the Mississippi Valley Conference, while Davenport schools Assumption, Central and West were part of the Quad-City Metro Conference. North Scott, which was participating in its first "big school" conference, had been in the Big Bend Conference (along with several smaller schools), and Burlington was not affiliated with any conference. At the time, the conference was known as the "Mississippi Eight."
