Two centuries ago, Pennsylvania became the center of prison reform due to Quaker influences which abolished harsh punishments established by English rule. However, conservative factions reintroduced cruel penalties like public hangings. Philadelphia prisons in the late 1700s were overcrowded and unsanitary, housing both men and women together, and jailers profited by charging inmates inflated prices. A Quaker formed an organization to provide food to starving prisoners, but it disbanded with the British occupation. A new Walnut Street jail had little improvement, with inmates trading clothes and suffering in the cold. By the end of the 20th century, the U.S. had over two million incarcerated, far surpassing other nations.
