Separate system

The separate system is a form of prison management based on the principle of keeping prisoners in solitary confinement. When first introduced in the early 19th century, the objective of such a prison or "penitentiary" was that of penance by the prisoners through silent reflection upon their crimes and behavior, as much as that of prison security. More commonly however, the term "separate system" is used to refer to a specific type of prison architecture built to support such a system.
