How did the system of feudalism restore order to Western Europe after the fall of the Roman Empire?

Feudalism restored order to Western Europe after the fall of the Roman Empire by creating a structured hierarchy of loyalty and land ownership. Lords granted land to vassals in exchange for military service and protection, while peasants worked the land in return for security and sustenance. This system established localized governance and social stability during a time of chaos, allowing communities to function and defend themselves against external threats. Thus, feudalism provided a framework that helped to maintain order in a fragmented and tumultuous landscape.
