A question for GROK - Dec. 24, 2025:
When and how widespread was the movement to house violent individuals in homes for the criminally insane?
--—
The movement to house violent individuals deemed criminally insane in specialized institutions emerged in the early 19th century, primarily as part of broader reforms in mental health care and criminal justice systems in Europe and the United States. It was driven by growing recognition that mentally ill offenders required separate treatment from both general prisoners and non-criminal mentally ill patients, influenced by humanitarian reformers and high-profile cases.In the United Kingdom, the catalyst was the 1800 case of James Hadfield, who attempted to assassinate King George III while experiencing delusions. His acquittal on grounds of insanity highlighted the need for secure detention, leading to the rapid passage of the Criminal Lunatics Act 1800 (formally "An Act for the Safe Custody of Insane Persons Charged with Offences").
This legislation allowed for the indefinite detention of those acquitted by reason of insanity for serious crimes, marking the formal beginning of distinguishing and housing "criminal lunatics" apart from ordinary criminals or the general insane.
Prior to this, such individuals were often confined in prisons, workhouses, or general madhouses without specialized care.
The County Asylums Act of 1808 further encouraged the building of public asylums, though initially slow in adoption, and the Lunacy Acts of 1845 made them compulsory, establishing centralized oversight via the Lunacy Commission.
Dedicated facilities followed, with Broadmoor Criminal Lunatic Asylum opening in 1863 as the first purpose-built high-security institution for violent or criminally insane individuals in England.
By the late 19th century, the system had become widespread in the UK, with criminal lunatics housed in county asylums, specialized institutions like Broadmoor, or wards within places like Bethlem Hospital; records from the era show quarterly returns tracking thousands across the country, with expansion continuing into the early 20th century under the 1890 Lunacy Act.
In the United States, the movement paralleled UK developments but was more decentralized, varying by state. Early 19th-century reforms, spearheaded by activists like Dorothea Dix in the 1840s, advocated for removing the mentally ill—including violent offenders—from prisons and jails into humane asylums, leading to a surge in state-funded institutions.
The first dedicated facilities for the criminally insane appeared in the mid-19th century, such as the Auburn State Asylum for Insane Convicts in New York (opened 1859) and later Matteawan State Hospital (1892).
Other examples include Ionia State Hospital for the Criminally Insane in Michigan (1885) and Bridgewater State Hospital in Massachusetts (1887). By the late 19th and early 20th centuries, the practice was widespread, with most states operating either separate hospitals or designated wards within general psychiatric institutions for violent or criminally insane individuals; at its peak in the 1950s, the U.S. had over 550,000 people in mental institutions overall, a significant portion including those from the criminal justice system.
In continental Europe, similar trends occurred around the same period. For instance, in Italy, criminal insane asylums were established post-unification in 1861, with forensic psychiatry developing dedicated facilities by the late 19th century.
The movement's spread was tied to moral treatment philosophies (e.g., Philippe Pinel in France, 1790s) and growing state involvement in public health, becoming commonplace in Western nations by the early 20th century before deinstitutionalization began in the 1950s-1960s due to new medications, civil rights concerns, and cost shifts to community care.
