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.
