England Northern Premier League

The Northern Premier League (NPL) was founded in 1968, as the northern equivalent of the Southern League, decades after the other two leagues at what is now the seventh tier of the English football league system, the Isthmian League and the Southern League. At that time they were the highest level non-League division below the English Football League, the same level as the other league in Northern England, the Northern League.

Over the next two decades, the NPL successfully displaced its older rival to become the pre-eminent regional competition in Northern England, with the Northern League eventually forced to accept status as feeder league to the NPL. In 1979, upon the creation of the Alliance Premier League (which later became the Conference and is now the National League), the NPL became a feeder league and fell down one level in the English football league system, and with the then-Conference's addition of regional divisions in 2004 the NPL was demoted by a further tier and there are now two levels between it and the English Football League.

From 1992–93 to 1994–95 the league's Division One included two non-English clubs, Caernarfon Town from Wales and Gretna from Scotland, who later joined their countries' league systems. Colwyn Bay, Bangor City, Newtown, and Rhyl have also played in the league.

In 2018, the NPL's member clubs voted 37–27, with one abstention and three clubs' absence, to split Step 4 (level 8) divisions from east to west starting from the 2018–19 season, and one year later, the league published its successful bid to add another division at Step 4 initially in 2020, further altering Division One into northwest and southeast for travel reasons. After the Football Association (FA) deferred its implementation of changes to the NLS, the NPL's additional division was created in 2021 instead.

Owing to title sponsorship deals, the league has been billed under various names, including a sixteen-year spell as the Unibond League, the longest such deal in world football. When this deal ended in 2010, a new deal was announced which saw the competition billed as the Evo-Stik League until the 2017–18 season. The League announced on 8 July 2019 that a two-year deal for seasons 2019-20 and 2020-21 had been agreed with new sponsor BetVictor. This sponsorship agreement with BetVictor was subsequently terminated early in April 2020 with a replacement, Entain's Pitching In, announced as the next sponsor for 2020–21. At the time of announcement, Entain went by its former name GVC Holdings. Under this partnership, the NPL is marketed as one of the three Trident Leagues, alongside its Isthmian and Southern counterparts.
