Prison
In 640 B.C., Ancus Marcius established the Mamertine Prison beneath ancient Rome, a network of dungeons contaminated with human waste where prisoners were held in squalid conditions. Before this era, imprisonment served primarily as detention for those awaiting trial or punishment rather than as a penalty itself. Ancient Greek philosophers like Plato began developing ideas to use punishment for reform instead of simple retribution. The Romans utilized existing structures such as metal cages and basements of public buildings to house prisoners. Forced labor on public works projects became a common form of punishment alongside slavery within ergastula, primitive prisons where unruly slaves worked at benches. In Medieval Songhai, trials could result in imprisonment as a specific form of punishment since various prisons existed throughout the empire. During the Middle Ages in Europe, castles and fortresses often functioned as makeshift prisons to hold citizens. The capability to imprison citizens granted legitimacy to officials at all levels of government and signified power over others. Public execution and torture remained the primary forms of punishment until popular resistance grew widespread in the late 17th century.
John Howard published The State of the Prisons in 1777 after visiting hundreds of facilities across Great Britain and Europe as high sheriff of Bedfordshire. He discovered acquitted prisoners still confined because they could not pay jailer fees and proposed housing each prisoner in a separate cell with professional staff paid by the government. Elizabeth Fry documented conditions at Newgate prison where women and children slept on straw in overcrowded cells described as a den of wild beasts. She founded a prison school for imprisoned children in 1816 and required women to sew and read the Bible while establishing supervision systems. Jeremy Bentham's panopticon model introduced observation towers allowing guards to see into one-person cells arranged in circular patterns without prisoners seeing the guards. The Penitentiary Act 1799 introduced solitary confinement and religious instruction but these state penitentiaries were never built due to committee disagreements. By 1842, Pentonville Prison opened beginning a trend of increasing incarceration rates and using prisons as the primary form of crime punishment. Robert Peel's Gaols Act 1823 prohibited irons and manacles while providing regular chaplain visits and paying jailers instead of letting them charge inmates.
Modern prisons often feature perimeter walls topped with razor wire or barbed wire alongside motion sensors and guard towers to prevent escapes. Decentralized podular layouts replaced 19th-century large landings with smaller self-contained housing units holding 16 to 50 prisoners around exercise yards. Officers monitor pods from central control stations where they can control cell doors and communicate throughout the facility directly. Maximum security facilities hold dangerous or disruptive prisoners while supermax prisons like ADX Florence keep inmates in lockdown for more than 23 hours daily. Meals arrive through chuck-holes in cell doors and each inmate receives only one hour of outdoor exercise alone under constant surveillance via closed-circuit television cameras. Minimum security prisons house white-collar criminals who rarely commit violent crimes and may allow free movement during daytime work activities. Suomenlinna prison in Finland has been open since 1971 allowing its 95 male prisoners to leave grounds daily to work in the township or commute to mainland Helsinki. Prisoners there rent flat-screen televisions and mini-refrigerators using wages ranging between 4.10 and €7.30 per hour earned through prison labor. Male prisons typically feature tall walls, towers, and barbed wire whereas female prisons often lack these severe security measures due to lower rates of violent offenses.
The World Prison Brief reported at least 11.5 million people were imprisoned worldwide in 2021 with the United States holding over 2 million inmates. This figure rose from 744,000 in 1985 making one in every 200 American adults a prisoner according to data from that year. The nonprofit organization Prison Policy Initiative estimated the U.S. government spent US$80.7 billion maintaining prisons in 2017 while CNBC calculated annual costs at US$74 billion. More than 800,000 people are employed within the U.S. prison industry constructing facilities and providing equipment like security systems and furniture. Revenues increase for businesses supplying transportation, communications, healthcare, and food as the population grows since their prosperity depends directly on inmate numbers. People who spend time in prison suffer greatest losses with subsequent annual earnings reduced by an average of 52 percent compared to those never incarcerated. Those convicted of felonies but not imprisoned see earnings drop by 22 percent while misdemeanor convictions reduce income by 16 percent on average. Sweden closed four prisons in 2013 due to significant drops in inmate numbers falling around 1% annually since 2004.
Forty percent of people in U.S. state prisons have disabilities compared to only 15% of the general population according to Department of Justice reporting. People with disabilities account for 46.2 per 1,000 age 12 or older being victims of violent crime while those without disabilities face 12.3 per 1,000 rate. In federal women's correction facilities of the United States, 70% of guards are male despite female inmates facing higher risks of sexual abuse. Two studies from the late 2000s noted that 40-57% of female inmates experienced sexual abuse in the past making them particularly vulnerable to further victimization. On average, 5% of women entering state prisons are pregnant and 6% of women in jails are pregnant according to Bureau of Justice Statistics 2007 data. Mothers frequently separated from babies after giving birth while some countries allow restraint during childbirth despite poor standards of care before and after delivery. Research shows significant links between incarcerated females and brain injury supporting findings that they are overwhelmingly victims of domestic violence mainly from men against women. More than 95,000 juveniles were locked up in U.S. prisons and jails in 2011 representing the largest youth prisoner population globally.
Countries including Sweden, Germany, and the Netherlands have sought to actively reduce prison populations through alternative sentencing methods. Fines, community service, house arrest, and mandatory treatment for drug offenders serve as common alternatives to traditional incarceration periods. Suspended sentences require probation terms where only broken conditions trigger actual prison time similar to Canadian conditional sentence concepts. Restorative justice programs arrange mediation between offender and victim so individuals can take responsibility by apologizing or returning stolen money. The prison abolition movement seeks to eliminate prisons altogether rather than merely reforming existing systems since abolitionists view imprisonment as inherently ineffective and discriminatory. This movement associates with libertarian socialism, anarchism, and anti-authoritarianism arguing imprisoning people for state-designated crimes is inexpedient and immoral. Prison reform organizations like Howard League for Penal Reform argue most prisoners would be more likely rehabilitated if receiving punishments other than prison itself. National Institute of Justice suggests better policing reduces crime rates more effectively than fear of punishment while Lawrence W. Sherman argues deterrence works through catching criminals not experiencing harsh penalties.
