The Alliance was formed in 1994, taking its initial member clubs from the West Midlands (Regional) League and the Midland Football Combination, which had existed since before the Second World War, having originally been formed as the Birmingham & District League and the Worcestershire Combination respectively. Their catchment areas had gradually converged, and by the early 1990s the standard of play and geographical coverage of the two competitions were considered to be similar enough that a new competition was formed to cater for the best clubs previously split across the two leagues.
