Answer:
serfdom, condition in medieval Europe in which a tenant farmer was bound to a hereditary plot of land and to the will of his landlord. The vast majority of serfs in medieval Europe obtained their subsistence by cultivating a plot of land that was owned by a lord. This was the essential feature differentiating serfs from slaves, who were bought and sold without reference to a plot of land. The serf provided his own food and clothing from his own productive efforts. A substantial proportion of the grain the serf grew on his holding had to be given to his lord. The lord could also compel the serf to cultivate that portion of the lord’s land that was not held by other tenants (called demesne land). The serf also had to use his lord’s grain mills and no others.

When you ask a question and you get TWO answers, not one, you'll see a crown sign at the bottom of that person's answer. You click on that crown thing and it will give them the brainliest. You can't do this when only one person answers though.
Hope this helps :)
