How did the system of feudalism restore order to western Europe?

Feudalism restored order to Western Europe following the collapse of the Roman Empire by establishing a hierarchical system of land ownership and reciprocal obligations. Lords granted land (fiefs) to vassals in exchange for military service and loyalty, creating a network of allegiances that provided stability. This structure allowed for localized governance and protection, as vassals managed the land and ensured security against invasions. Overall, feudalism facilitated social organization and economic productivity during a time of widespread chaos.
