How was a medieval peasant different from a slave in the ancient world?

A slave in the ancient world was a weak-willed creature who was forced to fulfill the will of his master. Slaves had no property, had no land, had no right to vote. They could be sold as a thing. The peasants in the Middle Ages were more free. They were mainly engaged in agriculture. They could have their own home and even their own land. They could start a family. Although the peasants were also forced to work for their owners.
