A new psychiatric institution emerged in the late nineteenth and early twentieth centuries: the psychopathic hospital. This institution represented a significant development in the history of psychiatry, as it marked the profession's reorientation from asylum-based to hospital-based care, and in this way presaged the deinstitutionalization movement that would begin half a century later. Psychopathic hospitals were also an important marker of psychiatry's efforts to redefine its professional boundaries and respond to its vociferous critics. This entailed both a rapprochement with general medicine in an effort to assert its scientific bona fides and a redefinition of its scope of practice to absorb non-certifiable 'borderland' cases in order both to emphasize non-coercive treatment and to enlarge the profession's boundaries.
