The Anti-WAAhnsinns Festival was a series of political rock concerts which took place in Germany during the 1980s. Its purpose was to support protests against the planned nuclear reprocessing plant Wackersdorf in Wackersdorf. In 1986, the fifth festival marked the peak of the protest movement against the plant. With over 100,000 people attending on 26 and 27 July, it was the largest rock concert in the history of Germany. The line-up included some of Germany's most popular music acts of the time such as BAP, Die Toten Hosen, Udo Lindenberg, Rio Reiser, Herbert Grönemeyer. The festival remained completely peaceful, contrary to government expectations. As a result of the overwhelming protests, the festivals resulted in unexpected media coverage for the anti-nuclear movement in Germany.
