The Spartan South Midlands Football League is an English football league covering Hertfordshire, northwest Greater London, central Buckinghamshire and southern Bedfordshire. It is a feeder to the Southern Football League or the Isthmian League, and consists of five divisions – three for first teams (Premier Division, Division One and Division Two), and two for reserve teams (Reserve Division One and Reserve Division Two).
The Premier Division is at step 5 (or level 9) and Division One at step 6 (level 10) of the National League System (NLS) respectively. Division Two, at level 11, and the reserve divisions are not part of the NLS.
The league was formed in 1997 by the merger of the Spartan League and the South Midlands League. It is also known as the Molten Spartan South Midlands Football League after its sponsors.
For the league's first "transitional" season, the members of the amalgamating leagues were split into three tiers, "Premier", "Senior" and "Division One". The top and bottom tier were split geographically into North and South Sections.
In 1998, the geographic sections were abolished, and a simple three-tier structure with promotion and relegation between the divisions was introduced.
| Season | Premier | Senior | Division One | |
|---|---|---|---|---|
| 1998–99 | Barkingside | Holmer Green | Bridger Packaging | |
| 1999–00 | Arlesey Town | Tring Athletic | Dunstable Town | |
| 2000–01 | Beaconsfield SYCOB | Letchworth | Pitstone & Ivinghoe |
In 2001, the Senior Division and Division One were renamed Divisions One and Two respectively.
