Teams promoted from Division One may enter the Central Wales Football League if standards and facilities fall into line with the regulations and criteria of the FAW and Mid Wales Football League (Tier 4 of the Welsh Football Pyramid).

The league was founded in 1904 as the Montgomeryshire & District League, and the first ten seasons before the First World War saw the league dominated by Aberystwyth Town, who won the inaugural title and two other championships, and Llanidloes who won five titles.

The league returned in the 1930s as the Montgomeryshire Junior League[1] and ran until the outbreak of the Second World War, when football was again suspended.

The 1950s were notable for five successive titles for Rodney Rovers, a club from Four Crosses, who played behind the Golden Lion public house.

The 1967–68 saw the league expand to two divisions, a format that continued until the 2021–22 season.
