What is feudilism?

Feudalism is a political and military system between a feudal aristocrat (a lord or liege), and his vassals. Feudalism flourished from the ninth century to the fifteenth century. In its most classic sense, feudalism refers to the Middle_AgesEuropean political system composed of a set of reciprocal legal and military obligations among the warrior nobility, revolving around the three key concepts of lords, vassals, and Fief. Although derived from the Latin Word feodum (fief), then in use, the term feudalism and the system it describes were not conceived of as a formal political system by the people living in the Medieval Period.
