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) 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.
