All-Ireland League (rugby union)
The All-Ireland League, known for sponsorship reasons as the Energia All-Ireland League, is the national league system for the 50 senior rugby union clubs in Ireland, covering both the Republic of Ireland and Northern Ireland. The league was inaugurated in the 1990–91 season.
The league is the second highest level of rugby union in Ireland, as professional teams representing the four provinces of Ireland play in the Pro14.
Division 1 sides may field no more than two professional players in their matchday sides, and only one may be a forward. Division 2 sides may not field professional players. Foreign professional players may not play in the League.
Competition format
The league is divided into five divisions of ten teams each. Teams play each other team in the division twice per season, for a total of 18 regular-season matches.The season runs from mid-September until mid-April, with an approximately four-week break in matches from mid-December to early-January. At the end of the season, the top four teams in division 1A enter a play off semi-finals and a final for the championship.
Promotion and relegation
At the end of each season the bottom team in division 1A is replaced by the top team in division 1B, with the second-bottom team entering a promotion/relegation play-off with the second-placed team in 1B. The bottom two teams in 1B, 2A and 2B are relegated and replaced by the top two teams from divisions 2A, 2B and 2C respectively.The two teams finishing bottom of division 2C are relegated to the relevant provincial league, and replaced by the two teams finishing top of a "round robin" tournament between the four provincial league winners. The four provincial junior leagues are the Connacht Junior League, the Leinster League, the Munster Junior League and the Ulster Championship League.
History
Prior to 1990, there was no national league in Ireland. Each of the four provincial unions had its own cup and league tournament. In 1991, after almost five years of discussion and consultation with clubs, the All-Ireland League was introduced with two divisions, division 1 with 9 clubs and division 2 with 10 clubs. The AIL was expanded to four divisions in 1993–94, with small variations in the numbers of teams per division in subsequent seasons.In 2000–01 the league was restructured to three divisions, each with 16 teams. After the 1995 introduction of professionalism in rugby union, the IRFU increased the importance of the provinces, which from 2002 participated in the Celtic League as full-time teams rather than ad hoc selections of club players. Therefore, the best Irish players no longer played in the AIL. In 2004 the IRFU proposed scrapping the All-Ireland League and reintroducing a provincial league system in 2005–06 which would act as qualifiers for a curtailed three division AIL structure in the second half of the season, but this model did not receive the support of clubs or rugby pundits. In 2007 the IRFU agreed that the structure of the All-Ireland League would remain as three divisions with 16 clubs each for seasons 2008–09 and 2009–10. In 2009–10, division 1 was split into 1A and 1B with eight teams in each as a trial and then continued in season 2010–11. In 2011–12 division 1A and 1B had 10 clubs each and divisions 2 and 3 were reformatted as divisions 2A and 2B with 16 clubs in each division.
