A peasant is a pre-industrial agricultural laborer or a farmer with limited land-ownership, especially one living in the Middle Ages under feudalism and paying rent, tax, fees, or services to a landlord. In Europe, three classes of peasants existed: non-free slaves, semi-free serfs, and free tenants. Peasants might hold title to land outright, or by any of several forms of land tenure, among them socage, quit-rent, leasehold, and copyhold.
