The document summarizes the Early Middle Ages in Europe following the fall of the Western Roman Empire. It describes how the decline of Roman influence left people vulnerable to invasion, leading them to enter feudal agreements with land-holding lords in exchange for protection. Society was organized into a hierarchy with nobles, clergy, and peasants. Peasants made up 95% of the population and spent their days farming the lands of nobles to fulfill their obligations under the feudal system. The Middle Ages saw invasions from Germanic tribes like the Angles, Saxons, and Vikings, influencing the development of Europe.
