The league was formed in 1951 with 14 clubs and was effectively a level below the Corinthian League. Due to the severe winter during the 1962–63 season the league was abandoned and an emergency competition played, in which the clubs were split into two groups, played each other only once. The two champions, Edmonton and Hertford Town, met in a two-legged final, with Edmonton winning 5–2.
