The Rugby League Championships (known as the National Leagues between 2003-2008) are the two professional divisions below the Super League, consisting of 12 teams in the Championship and 14 teams in League 1. Promotion and relegation is in use between the Championship and League 1 as well as between the Championship and Super League but not between League 1 and the National Conference League and French Elite One Championship. The RFL can promote teams between the NCL, Elite One Championship and League 1.
A second division in rugby league was first formed in 1902 when the RFL Championship split. The RFL Second Division lasted for three seasons and was not played again until 1962 where it was played for just two seasons. It did not become a regular competition until the 1973-74 season.
Another division was added in 1991, the RFL Championship Third Division, which was played for two seasons until 1993. It was then reinstated during the 1995-96 season, the last winter season of rugby league and then played twice more during the summer era until 1997.
In 2003 the Third Division was reinstated again beneath the second division but under the names National League 1, National League 2 and a National League 3 was established Consisting of teams from the Conference. This three division structure lasted until 2008 and the National League 3 was scrapped.
In 2009 the National Leagues were changed to become the Championship and Championship 1. There would be no promotion to Super League and teams would have to apply for a licence every few years for entry to play in Super League. The Grand Final, previously to decide who was promoted now decided the champions. The number of teams in the Championships varied each year as the RFL expanded them and introduced new teams.
In 2015 the RFL reintroduced promotion to Super League and a new league structure, the Super 8s. The Championships were now called the Championship, consisting of 12 teams, and League 1, consisting of 14 teams.
