Cumbria (1993–1996) The Cumbria league was formed from teams from the old
North-West North 1 division when it was disbanded at the end of the 1991–92 season. Promotion was to
Cumbria/Lancs North and as the basement division for clubs in the region there was no relegation. Initially a tier 10 league, the creation of
National 5 North for the 1993–94 season meant that Cumbria/Lancs North dropped to become a tier 11 league.
Cumbria (1996–2000) The league system was restructured from top to bottom by the
Rugby Football Union for the start of the 1996–97 season. The cancellation of
National 5 North and creation of
North West 3 meant that Cumbria remained a tier 11 league, with promotion into
North Lancs/Cumbria (formerly Cumbria/Lancs North).
Cumbria (2000–2018) Northern league restructuring by the
RFU at the end of the 1999–00 season saw the cancellation of
North West 1,
North West 2 and
North West 3 (tiers 7 to 9). This meant that Cumbria became a tier 8 league, with promotion continuing to
North Lancs/Cumbria. As the lowest ranked league for clubs in the region there was no relegation until the introduction of
Cumbria 2 at the end of the 2017–18 season.
Cumbria 1 (2018–2019) Restructuring of the north-west leagues at the end of the 2017–18 season, including the cancellation of
North Lancs/Cumbria and the introduction of
Cumbria 2, meant that Cumbria was renamed to Cumbria and became a tier 7 league. Promotion was now up to
North West 1 while relegation was to the new Cumbria 2.
Cumbria (2019–2022) After just one season
Cumbria 2 was cancelled and Cumbria 1 reverted to being a single division named Cumbria, while the introduction of
North 2 West for the 2019–20 season meant that Cumbria dropped back to being a tier 8 league with promotion into this new division and no relegation. Adult community leagues were cancelled for the 2020–21 season. In 2021–22 the league was contested by nine teams and the league restructure meant that no teams were promoted at the end of the season.
Counties 1 Cumbria (2022–present) Following the RFU Adult Competition Review, Counties 1 Cumbria reverted to a level 7 league, with promotion to
Regional 2 North. There is no relegation. ! style="background:#efefef; width:40px;"|No of teams ==Promotion play-offs==
