Now, another term or sometimes a subcategorization of serf in the Middle Ages is the term villain. And I know what you're thinking. You have heard that term before. The villain today means a bad guy. But the term originally comes from the Roman Empire when Diocletian, the famous emperor who persecuted Christians, he also, because they were having trouble getting labor in rural villas, he began to decree that certain people had to work in the villas. And so someone who was compelled to work at a villa was called a villain. And so they were bonded to the land.
