The Spartan South Midlands Football League was formed in 1997 following the merger of the
Spartan League and the
South Midlands League. The inaugural 1997–98 season operated as a transitional structure and consisted of five divisions: Premier Division North, Premier Division South, Senior Division, Division One North and Division One South. These divisions were populated by clubs from the two predecessor competitions. At the end of the first season, the two Premier Divisions were merged to form a single Premier Division for the 1998–99 campaign. The two Division One sections were also discontinued after 1997–98, with the league operating a single Division One from 1998–99 onwards. ==Current Spartan South Midlands League members==
