How did the feudal system divide up the people?

The feudal system divided people into distinct social classes based on land ownership and obligations. At the top were the monarchs, who granted land to nobles (lords) in exchange for military service. Below the lords were vassals and knights, who served the lords in return for protection and land. At the bottom were the peasants and serfs, who worked the land and provided food and labor, often with limited rights and freedom.
