A serf is an unfree medieval peasant who owes labor services on a manor. It is important to understand that serfs are NOT the same thing a slaves. Serfs had their own property, money, and directed much of their own time. A serf could not move way from the manor without permission, and theytypicallyowed about two days of labor each week, but otherwise where able manage their own affairs. A serf could not be sold to another manor, nor could they be deprived of their land holdings in the village fields (if they had such holdings).
