A review is made of the anti-psychiatric movement through its major protagonists, Lacan, Laing, Cooper and Szasz. The ideology was set to challenge the concept of mental illness and question the authority of the psychiatrist and the need for mental health institutions. The anti-psychiatric movement received a lot of attention in the 1970s but is now considered to be of the past and of likely interest to the psychiatric historian. However, the impact of the movement on current psychiatric practice requires further re-examination and appraisal.
