Chaos Days (German: Chaostage) was an annual punk gathering, often violent, held in Hanover, Germany starting in 1982 and revived in the mid-1990s.
[1] The gathering was intended to protest a police plan to create a reference library of photographs of German punks.
[5][4] These "chaos days" were the main topic of TV debates and newspapers for several weeks.
Terrorgruppe wrote a now-classic song about the Chaostage titled "Wochenendticket" (released as a single in 1996), which is named after the train ticket that most punks used in order to get to Hanover from all across the country.
The band Church Of Independent Assholes (CIA) rewrote the classic Rio Reiser song "König Von Deutschland" and included a reference to the Chaostage in it.
