Division 1 is the third level in the league system of Swedish football and comprises 28 Swedishfootball teams. Division 1 had status as the official second level from 1987 to 1999, but was replaced by Superettan in 2000; however, it was recreated for the 2006 season as the third tier below Superettan.
The old Division 1 replaced Division 2 as the second highest level in 1987 and consisted of two separate leagues with 14 teams each, Norra (Northern) and Södra (Southern), except for the 1991 and 1992 seasons which comprised 32 teams in four leagues, adding Östra (Eastern) and Västra (Western).
There are 28 clubs in Division 1, divided in two groups of 14 teams each representing Northern and Southern Sweden. During the course of a season (starting in April and ending in October) each club plays the others twice, once at their home stadium and once at that of their opponents, for a total of 26 games. At the end of each season the three lowest placed teams of each group are relegated to Division 2 and the six winning teams from the six Division 2 leagues are promoted in their place. The top team in each Division 1 group is promoted to Superettan and the two lowest placed teams from Superettan are relegated in their place. The second placed teams in each Division 1 group plays a promotion/relegation play-off against the third and fourth lowest teams in Superettan.
