Manorialism
Manorialism, also known as seigneurialism, the manor system or manorial system, was the method of land ownership (or "tenure") in parts of Europe, notably France and later England, during the Middle Ages. Its defining features included a large, sometimes fortified manor house or castle in which the lord of the manor and his dependents lived and administered a rural estate, and a population of labourers or serfs who worked the surrounding land to support themselves and the lord.
