The most accurate response regarding the impact of the Western Roman Empire on feudal societies in Europe is:
The fall of the Western Roman Empire led to an increasing dependence on feudal societies as regional powers vied for control of land.
After the collapse of centralized Roman authority, Europe experienced a fragmentation of power, leading to the rise of local lords and vassals who managed land and offered protection in exchange for service. This situation fostered the development of feudalism, as communities became increasingly reliant on local leaders for security and governance amidst the chaos and instability of the post-Roman period.
