Rock am Ring was originally planned as a one-time festival on the Nürburgring motorsports complex, celebrating the inauguration of a newer, shorter version of the race track in 1985, but due to its commercial success (with 75,000 audience members), it was decided to make the concert an annual event. However, after a dip in attendance for the 1988 event, the festival was put on hiatus for two years. In 1991, the festival returned with a new concept: as well as featuring well-known artists, event organizers present lesser known up-and-coming bands to the public. In 1993, Rock im Park took place for the first time in Vienna. For the 1994 event, Rock im Park moved to the disused Munich-Riem airport, and the following year to Munich's Olympiastadion, where it found a home for the 1995 and 1996 event. In 1997 Rock im Park moved to Nuremberg's Frankenstadion where it was held until the venue was unavailable in 2004 because the stadium was being renovated for the 2006 Football World Cup. Since 2004 the venue moved again to the current Zeppellinfeld, where Rock im Park was since held with the exception of the 2006 festival, which was moved to the Luitpoldhain.
On the evening of 2 June 2017, the first day of the festival, the sold-out event with about 85,000 visitors was interrupted at 9:00 pm during a performance by the Düsseldorf band Broilers and the festival grounds cleared. The reason given was a terrorist situation. Other scheduled performances for Friday evening, including those of the headliner Rammstein and the rapper Marteria, were cancelled. Three men were arrested and checked in Hesse that same evening. Two of the men assigned to the Salafist scene in Hesse had access rights in the form of bracelets, which gave them direct access to many festival areas. One of the men was also suspected of having links to the terrorist scene. However, on the morning of 3 June, after a search of the grounds and a raid of the suspect's homes, the police announced that the suspicion of a threatening attack had not been substantiated, so that the festival could continue on Saturday noon. The access rights to the festival site had been received by the two main suspects due to a short-term staffing request from an external security service provider. 2b1af7f3a8
