The term 'Bond Servant' is a general term used to describe a person who is bound to serve another person or entity. The two most common types of Bond Servants are Serfs and Slaves. A SERF is a person who is bound to the land they work on and is subject to the will of their lord or master. A SLAVE is a person who is owned by another person and is forced to work without pay or freedom. Both Serfs and Slaves are considered Bond Servants, as they are both bound to serve another person or entity.
