The first use of prisons in England was to detain an accused until trial or to keep a convicted criminal until execution. Under the Anglo-Saxons and the Normans, and throughout the Middle Ages, criminals were punished by fines and, for serious crime, death or mutilation. The first prisons were therefore the local lock-up or the castle keep.
In the sphere of civil law, each central court of common law had its prison (such as the Marshalsea for the Court of King's Bench). Imprisonment for contempt of court was and still is possible and the Court of Chancery became notorious for imprisoning those who were deemed to be in contempt. Imprisonment for debt was also common and was not abolished until late in the 19th cent.
During the 19th cent. prison became an important penal sanction though it was not until the 1850s that it became the prevailing form of punishment, especially after the end of transportation. Overcrowding, dirt, and low hygiene as well as a miserable diet made the prisons breeding places for disease such as typhoid—indeed an illness known as ‘gaol fever’ was common, and many inmates died in prison.
In the 18th cent. certain reformers became aware of the appalling conditions in English prisons—two of the most famous being John Howard, the great prison reformer who gave his name to the Howard League for penal reform, and Elizabeth Fry who worked for the improvement of the lot of women in prison.
In 1865 the principle was introduced of work for prisoners. In 1895 the Gladstone Committee was set up to review the prisons and reform followed. Gradually during the 20th cent. corporal punishment, penal servitude, and hard labour were abolished for prisoners and the rehabilitative aspect of prison re-emphasized.
