Read the excerpt from The Land.

This refers to a person who has property rights over a piece of land and this is his legal right to live there or engage in other activities.

With this in mind and from the given excerpt, we can see that the narration talks about post-Civil War America when land owners were very powerful but Paul's father does not abuse his power and privileges.

This is because he remains kind and fair to the people he had power over as a result of his status as a landowner.
