The deterrent workhouse, with its strict rules for the behavior of inmates and boundaries of authority of the workhouse officers, was a central expression of the Poor Law Amendment Act of 1834, known widely as the New Poor Law. This article explores for the first time the day-to-day experience of the power and authority of workhouse masters, matrons, other officers of the workhouse, and its Board of Guardians, and the resistance and agency of resentful inmates. Despite new sets of regulations to guide workhouse officers in the uniform imposition of discipline on residents, there was a high degree of regional diversity not only in the types of offenses committed by paupers but also in welfare policy relating to the punishments inflicted for disorderly and refractory behavior. And while pauper agency was significant, it should not be overstated, given the disparity in power between inmates and workhouse officials.
