With feudalism, the king or monarch was the highest person in feudal society. The king was in charge of taxation and the affairs of the kingdom. The king gave the lords land(manor), and the lords provided the king with protection and loyalty. The king gave large pieces of land, or fiefs, to warriors and vassals who swore their oath of fealty. That was the role of the king in feudalism.
The lords were the second most important persons in the feudal society. The lord’s day consisted of hunting, defending manors, and overseeing the serfs or peasants. They also settled legal disputes. They were important because they were powerful and worked in the clergy. The lords gave the knights food and land. In return, they received protection and loyalty. That was the job of the lords in the feudal society.
The knights were the third rank in feudal society. They used most of their days practicing for battle, jousting, and entertaining people. They also had to study a code of conduct which was called chivalry. Their importance to European feudalism was to be in battle and to fight in wars. The knights have protection and loyalty to the lords, and in exchange, they received food and land. That was the role of the knights in feudal society.
The serfs are the lowest ranking group in feudal society. The serf had to do their own cooking and cleaning. They also worked for land. They have the lords food and the lords gave then land to live on along with protection. Serfs made up 80% of the opoulation. That the role of the serf in feudal society.
Since feudalism is in place, its affects everyone - kings, lords, knights, and serfs. The king's provide the lords with land and received protection and loyalty. The lords gave the knights food and received protection. The serfs gave the lords food and got land to live on. That is what Eurpoean feudalism was like.
