In England, during the 18th and 19th centuries, 10,000 people were imprisoned for debt each year. A prison term did not alleviate a person's debt, however; an inmate was typically required to repay the creditor in-full before being released. In England and Wales, debtors' prisons varied in the amount of freedom they allowed the debtor. With a little money, a debtor could pay for some freedoms; some prisons allowed inmates to conduct business and to receive visitors; others (including the Fleet and King's Bench Prisons) even allowed inmates to live a short distance outside the prison—a practice known as the 'Liberty of the Rules'—and the Fleet even tolerated clandestine 'Fleet Marriages'.
