The Aktionsanalytische Organisation (AAO), commonly known as the Friedrichshof Commune, was an Austrian far-left commune in Friedrichshof outside Vienna and authoritarian sect (described as a "psycho sect" by authors Nordhausen and Billerbeck)[1] that was founded by Otto Muehl in 1972 and dissolved in 1990. Muehl was subsequently convicted of widespread sexual abuse of minors who lived in the commune and sentenced to 7 years in prison.
