Serfs were mostly peasant farmers who provided labor in their masters land. Peasants would pay the lord by working for them in exchange to use their lords land to generate their own food. Serfs did not have money. they were basically slaves. They would work at least three times a week. The serf was bound to work in a single manor. The status of serf was passed down to their children.
