The league was formed in 1994, drawing its initial membership from the strongest clubs in the Midland Football Combination and the West Midlands (Regional) League, both of which became feeder leagues to the new competition. Each season, the champion club of each feeder league was eligible for promotion to the Alliance, and Alliance clubs could in turn be relegated to the feeder leagues. Successful teams in the Alliance were eligible for promotion to a Step 4 league, either the Southern League or Northern Premier League depending on geographical considerations. The league merged with the Midland Combination in 2014 to form the new Midland Football League.
