Migration was common in medieval England. Serfdom, however, in theory severely restricted the mobility of villeins. This article explores servile migration through a close study of the manorial court rolls of the manors of Great Waltham and High Easter (Essex). By doing so, it contributes to ongoing debates over the nature and decline of serfdom in medieval England and over the role of towns as destinations for migration, which has been seen as contributing to the ‘Little Divergence’. Firstly, the article establishes the extent of servile migration as recorded in the manorial court rolls. In keeping with recent studies, almost half of recorded servile migrants stayed within ten miles of their home manor and, significantly, a sizeable majority (around two thirds) opted for rural destinations. The article then explores some dynamics of servile migration in detail. It suggests that enforcement of restrictions on the movement of villeins was attempted in the 1350s but that, in practice, the lord's coercive capacity was distinctly limited and ineffective.
