The Azadegan League (Persian: ليگ آزادگان) (also called 1st Division) is the second-highest division league in the Iranian football league system after the Persian Gulf Pro League. Each year the top teams from each group are directly promoted to the Iran Pro League, while the two second placed teams play each other in a home and away play-off to get the chance to play in the Iran Pro League play-off. The two last placed teams in each group are directly relegated to the 2nd Division.
In 1991 the league was founded as Iran's top division. But, after the creation of the Persian Gulf Pro League in 2001, the Azadegan League was declared as the second highest football league in the county.
In 1991, the national league was named to Azadegan League in honor of the Iranian prisoners of war who were released.[clarification needed] The number of teams, playing in the league, varied from year to year. Pas and Saipa dominated the league in the first four years. Pas and Esteghlal both were also able to capture Asian Club Championships in the early 1990s. By the mid-90s Persepolis and Esteghlal regained their dominant form and the league champions in the period of 1995-2001 was either Esteghlal or Persepolis.
Until 2001 the league was the highest division football league in Iran, but that changed when the Iranian Football Federation decided to start a professional league. The Persian Gulf Pro League was created and since then, the Azadegan League became the second-highest division in the Iranian football league system.
All teams in the Azadegan League are entered in the Hazfi Cup, if any club from the Azadegan League wins the cup, they participate in the AFC Champions League. Since 2001, when Azadegan League became the second-highest division league, no team from Azadegan League has became Hazfi Cup champion. Gostaresh Foolad is the only club from the Azadegan League that has reached the final of the Hazfi Cup.
The Azadegan League consists of two subdivisions, each having 12 teams. The top teams in each group are automatically promoted to the Persian Gulf Pro League, while the second place teams play each other in a home and away play-off to decide the third and last promotion spot. The eleventh and twelfth placed teams in the groups are automatically relegated to the 2nd division. Sometimes the playoff match format is not used and one match takes place between the teams on a neutral ground instead.
