The Auburn system (also known as the New York system and Congregate system) is a penal method of the 19th century in which persons worked during the day in groups and were kept in solitary confinement at night, with enforced silence at all times. The silent system evolved during the 1820s at Auburn Prison in Auburn, New York, as an alternative to and modification of the Pennsylvania system of solitary confinement, which it gradually replaced in the United States. Whigs favored this system because it promised to rehabilitate criminals by teaching them personal discipline and respect for work, property, and other people.
