What can be the definition of feudalism?

Feudalism is a social and economic system that dominated medieval Europe, in which land was owned by kings and lords and leased to vassals in exchange for loyalty and military service. This system created a hierarchical society with a rigid class structure, where power and wealth were concentrated in the hands of a few noble families.

Feudalism is a medieval system of government in which the land was divided into fiefs, and each fief was ruled by a lord, or feudal lord. The lord had certain rights and privileges, including the right to collect taxes from his peasants, and the right to demand military service from them. In return, the lord was supposed to protect his peasants from outside attack and provide them with justice.
