Answer:
Correct answer is serfdom.
Step-by-step explanation:
During the Middle Ages most of the European states were feudal states. It meant that the ruler (senior) distributed land to his lord (vassals) who had certain obligations towards the senior. Still, most of the hard work was done by peasant. Life of peasant was harsh, but there was a great difference between serfs and freeman.
Serf practically had no rights. They could not live property, and they could not own property. Without the permission of the landowner they could not even get married.
