The development of the poor law has formed a key element of recent discussions of ‘state formation’ in early modern England. There are, however, still few local studies of how formal poor relief, stipulated in the great Tudor statutes, was implemented on the ground. This article offers such a study, focusing on Lancashire, an economically marginal county, far from Westminster. It argues that the poor law developed in Lancashire surprisingly quickly in the early seventeenth century, despite the fact that there is almost no evidence of implementation of statutory relief before 1598, and formal relief mechanisms were essentially in place before the Civil War even if the numbers on relief remained small. After a brief hiatus during the conflict, the poor law was quickly revived in the 1650s. The role of the magistracy is emphasized as a crucial driving force, not just in the enforcement of the statutes, but also in setting relief policy. The thousands of petitions to JPs by paupers, parishes, and townships that survive in the county archives suggests that magistrates were crucial players in the ‘politics of the parish’.
