Željezničar always had great support from fans all over Bosnia and Herzegovina and Yugoslavia (when Bosnia was a part of Yugoslavia ). When Željeznicar won Yugoslav First League in 1971–72 season, fans followed their club across Yugoslavia.
In 1976–77 season Željeznicar was relegated from Yugoslav First League, but that didn't stop fans to follow Željo in second league, so the average attendance at Grbavica Stadium was 10 000 which wasn't often in Yugoslav Second League, and after one season in second league Željeznicar won promotion and was again in first league.
During that time the most passionate Željeznicar fans were located on the south stand of Grbavica Stadium . Željeznicar was a club supported mainly by working class citizens,and their city rivals FK Sarajevo by upper class.
In 1981 Zeljeznicar played in Yugoslav Cup finals against FK Velez Mostar. Match was played at Marakana stadium, and attendance was 40 000. The Željeznicar fans were on the east side of stadium. Despite the great support Željo lost the finals.
The best moments oh their history Željeznicar had when they played the semi-finals of UEFA Cup in 1984–85 soason. That year except in Sarajevo Željo had a support in other cities such as Konjic, Travnik, Lukavac and there was a group of Željo fans in Novi Sad.
In 1987 the most passionate fans of Željeznicar formed an ultras group called The Maniacs. The Maniacs are located on south stand of Grbavica. There was also formed subgroups Blue Tigers and Joint Union.
After the breakeup of Yugoslavia and when Bosnian War start, Grbavica a quarter of the city of Sarajevo where Grbavica Stadium is located was on front lines of battle between Bosnian army and Bosnian Serbs forces. Many members of The Maniacs joined Army of the Republic of Bosnia and Herzegovina and Zelene beretke. One of them was Dževad Begić-Đilda. He was one of the founders and leader of The Maniacs. Dževad Begić was killed 1992 by sniper shot when he was trying to save wounded civilians.
The most important day of every Maniac is 2 May 1996 when Željezničar played their first match on Grbavica Stadium after war, the stadium was rebuilt because of heavy structural damage (west stand was completely demolished and burned in war). That day in front of 20 000 Sarajevans FK Željezničar Sarajevo played against FK Sarajevo. The game end in a draw 1:1.
