Serfdom is a legal and economic system. A serf is a worker who has to stay in one area. Serfs were the lowest social class of the feudal society. Serfs were different from slaves. Serfs could have property. In most serfdoms, serfs were legally part of the land, and if the land was sold, they were sold with it. Serfdom is the forced labour of serfs, on the fields of the land owners. Serfs got protection and the right to work on the leased fields. Serfs worked in fields, and other agricultural-related works, like forestry, transportation (both land and river-based), work in craft and even in manufacturing.
Serfs & Peasants in Mediveal Times. There are 3 types of peasants that may have lived on the manor, Slaves, who could be bought and sold, Serfs, who had no political rights, and Freemen, who owned small parts of the land. The name of our role is peasant/serfs. The Peasants and serfs were very important in the Middle ages, because they tended to the crops and mended the land. If there weren't any peasants or serfs, there would probably be no food.
