The origins of the English Poor Law system can be traced back to late medieval statutes dealing with beggars and vagrancy, but it was only during the Tudor period that the Poor Law system was codified. Before the Dissolution of the Monasteries during the Tudor Reformation, monasteries had been the primary source of poor relief, but their dissolution resulted in poor relief moving from a largely voluntary basis to a compulsory tax that was collected at a parish level. Early legislation was concerned with vagrants and making the able-bodied work, especially while labour was in short supply following the Black Death.
