During which dynasty did the system of feudalism emerge?

Feudalism emerged during the early Middle Ages, particularly during the Carolingian Dynasty in the 9th century. This system became more pronounced in Western Europe following the decline of centralized power after the fall of the Roman Empire. It was characterized by a hierarchy of lords and vassals, where land was granted in exchange for military service and loyalty. The fragmentation of authority during this period facilitated the rise of feudal relationships.
