What is the role of Knights and serfs?

Knights were mounted warriors who served a lord in exchange for land and protection, often participating in battles and upholding chivalric codes. They provided military service and maintained order within their domain. Serfs, on the other hand, were agricultural laborers bound to the land, working for the lord in exchange for protection and the right to cultivate certain plots for their own sustenance. Together, knights and serfs formed a vital part of the feudal system, with knights ensuring security and serfs providing the necessary labor for the economy.
