After the Yugoslav wars, Željezničar became one of the most important members of the Football Association of Bosnia and Herzegovina and of the Bosnian Premier League, of which they have been proclaimed champions on four occasions. Their greatest European achievement was reaching the semi-finals of the UEFA Cup in the 1984-85 season, when they lost to Videoton on the away goals rule, while their greatest achievement in Europe as a Bosnia and Herzegovina club was in the 2002-03 Champions League, reaching the third qualifying round, where they were eliminated by Newcastle United.
