Moral treatment was an approach to mental disorder based on humane psychosocial care or moral discipline that emerged in the 18th century and came to the fore for much of the 19th century, deriving partly from psychiatry or psychology and partly from religious or moral concerns. The movement is particularly associated with reform and development of the asylum system in Western Europe at that time. It fell into decline as a distinct method by the 20th century, however, due to overcrowding and misuse of asylums and the predominance of biomedical methods. The movement is widely seen as influencing certain areas of psychiatric practice up to the present day. The approach has been praised for freeing sufferers from shackles and barbaric physical treatments, instead considering such things as emotions and social interactions, but has also been criticised for blaming or oppressing individuals according to the standards of a particular social class or religion.
