法羅群島乙級聯賽

The league was founded in 1943 and was named Meðaldeildin (The Middle Division): this was 1 year after the founding of the Meistaradeildin, the original top level Faroe Islands football league. There was no promotion and relegation system at the time, and the two leagues operated separately from each other. This was partly because Meðaldeildin was mostly made up of B teams from the clubs in the Meistaradeildin. One year after all leagues had to be suspended due to the British occupation of the Faroe Islands. The league then resumed in 1945. From 1943 to 1975 it was called Meðaldeildin, then the league structure changed in 1976.

The Meistaradeildin was renamed 1. deild and the Meðaldeildin was renamed 2. deild. Also from that season onwards, the top clubs in 2. deild were promoted to 1. deild. The first club to be promoted was Fram Tórshavn after they won the division for the first time in their history, though they finished bottom of 1. deild the following season and were relegated back into 2. deild. The latest change to the league was made in 2005, when 1. deild was renamed as Formuladeildin for sponsorship reasons; 2. Deild adopted the name of 1. Deild; the third tier was renamed 2. Deild and the fourth tier became 3. Deild.

It currently has 10 participating teams. At the end of each season, two teams are relegated and two promoted from what is now the fourth division, pending the fact that the winning team in any given division doesn't already have a senior team in the division it is being promoted to. In such cases the team that finished second will be promoted in its stead. If a team is relegated to a division where one of its teams are already playing, the second best team will move one division down, thereby saving another team from relegation.

At the end of the 2008 season, Fram, who were set to be renamed FC Hoyvík for the 2009 season and AB II finished in the promotion places. Fram (now FC Hoyvík) were promoted to 1. deild, while AB II would only be promoted if their 1st team finished in one of the promotion places in 1. deild. AB's first team eventually won promotion into the Vodafonedeildin, finishing runners-up in 1.Deild. However, AB II were denied promotion to 1.deild and MB Midvágur who finished 3rd in 2.Deild, were promoted instead. Because AB II who finished 2nd, had used illegal players. Though there is still an ongoing debate whether they finished 2nd or 3rd and which team should have been promoted. The following season in 2009 MB Midvágur finished bottom in 1.Deild, only picking up 8 points and were relegated back into 2.deild. Meanwhile AB Argir II won the 2.deild in 2009 and were promoted to 1.deild.
