The statement that accurately compares feudalism and manorialism is:
Both controlled relationships between those who owned land and those who did not.
Feudalism primarily deals with the hierarchy and relationships between lords, vassals, and knights regarding land ownership and military obligations, while manorialism focuses on the economic and social relationships between the landowners (lords) and the peasants (serfs) who worked the land. Both systems involve the dynamics of land ownership and subordination, but they emphasize different aspects of medieval society.
