In "A Distant Mirror: The Calamitous 14th Century," Barbara W. Tuchman explores the roles assigned to different social classes during medieval times. The clergy had the duty of praying for the well-being of all individuals, acting as spiritual leaders and intermediaries with the divine. Their prayers were seen as vital for the protection and guidance of society. In contrast, knights were tasked with defending the realm through warfare. They represented the military strength of the society, using their skills to protect the people from external threats. On the other hand, commoners carried the responsibility of working the land and producing food, ensuring that everyone had the sustenance necessary for life. This division of labor highlights the interdependence of social roles in that era.

The clergy were to pray for all men, the knight to fight for them, and the commoner to work that all might eat.
