The origins of social psychiatry can be traced to the age of enlightenment and to the effects of the industrial revolution. Social psychiatry deals with social factors associated with psychiatric morbidity, social effects of mental illness, psycho-social disorders and social approaches to psychiatric care. Since the end of World War II up to the early seventies it has been claimed that social psychiatry should concentrate on the fight against war, poverty, racial discrimination, urban decay and all other social ills affecting people's mental health, and that the psychiatrist should be responsible for the mental health of the society. In contrast, sociology of mental health questioned the expertise of the psychiatrist and the very existence of mental illness, claiming that it covers deviant behaviour rejected by the society.
