The early medieval cultivators were mainly unfree, forced to work on the lord's demesne in return for their strips in the open fields. From the 14th century wage labour replaced the feudal labour system. By the 16th century, most landowners were renting or leasing most of their land and paying cash for labour to cultivate what remained. In 1535, for example, the manor of Drayton was worth £9 4s. 8d. annually, and the lion's share, £5 18s. 2d., came from money rents.
